Even in the 1920's and 1930's conflicts occurred between those who sought to exploit these stands and those who sought to protect them. Both of these must be studied in their mature stage. Kauri Pine contributed much of the folklore of North Queensland but not to the same extent as in New Zealand. the male cones are cylindrical (4-10 cm long and 7-15 mm wide) and made up of hundreds of tiny spore-bearing structures. The male (pollen) cones are narrow reddish brown and cylindrical, 2 to 3 inches in length and erect when held on the tree but curled slightly when dropped to the ground. Fruit and seed description Fruit: mature seed cones oval, 9-10.5 cm x 7.5-9.5 cm, seed bracts roughly obtriangular with a small projection near the base on one side. Cycas siamensis Miq: It is found in Myanmar, Thailand, China and Laos. Cones about 8-10.5 cm diameter each with about 340-440 scales per cone. The Kauri (Agathis Australis) is a native tree of New Zealand from the Jurassic period. The Forestry Department of the day imposed girth limits to protect the growing stock from industry. Female (seed) cones are globular, 8–13 cm across, and are borne on short woody stalks. Bark smooth and light grey to reddish, peeling with large thin irregular flakes that thicken on larger trees, leaving a pitted somewhat rough reddish brown surface, emits a milky sap when punctured. Male cones cylindrical, 3-6 cm long by 1 cm wide, on a stout peduncle 1 mm wide; sporophylls imbricate, margin weakly erose. robusta, syn. Seeds of some species are attacked by the caterpillars of Agathiphaga, some of the most primitive of all living moths. Agathis australis cone and leaves - Buy this stock photo and explore similar images at Adobe Stock The male pollen cones appear usually only on larger trees after seed cones have appeared. nesophila has mature pollen cones 9-13 mm wide and microsporophyll heads rhombic, not raised, 1.5-2 mm wide (Farjon 2010). Male cone is shortly stalked and ellipsoidal to oblong in shape. Stairs carved into an ancient kauri trunk (Ancient Kauri Museum, Awanui, near Kaitaia, Northland, New Zealand) Gum from a kauri tree, sold in Kauri Museum, New Zealand Male cones cylindrical, on a peduncle to 15 mm long, 25 to 38 mm long, 13 mm wide, base subtended by 2 large bracts, surface of cone loose. Each male cone contains several microsporophyll’s and each microsporophyll bears many microsporangia (Fig. Cotyledons lanceolate with a number of veins arising at the same point at the base and continuing +/- parallel to the apex. Male cones less than 3 cm long, distinctly pedunculate. Agathis robusta is a slow-growing but long-lived large evergreen conifer that can reach a height of 25 - 30 metres, exceptionally to 43 metres. nesophila occurs in New Guinea. Female cone subglobose, on a short peduncle, 6 cm long by 6-8 cm wide, glaucous-green, scales 1.8 cm long with a short mucronate umbo (1). Male cones 20-50 mm long, stout, cylindrical, female cones globose 50-75 mm diam., cone-scales (carpidia) deciduous, at first broad but then gradually narrowing toward base, bearing one ovule per scale. the larger female cones (9-15 cm long and 8-10.5 cm wide) contain numerous densely packed seed-bearing scales. Leaf blades about 5-13 x 1-4 cm. A. robusta subsp. Seeds ovoid, compressed, margins winged. Every spring, the pollen from the male pine cones are released into the air where they may eventually land on a scale on the female cone. – Agathis robusta subsp. ~ Male Kauri Cone pendant ~ 48mm tall (1.9 inches). Male cones elongate, the microsporophylls with 5–15 abaxial pollen-sacs in Agathis, 8–15 in Araucaria. Female cone globose, 63 mm long by 45 mm wide, purplish, maturing in 2 years; scales 32 mm long by 25 mm wide. Male cones change from light green to brown when they are mature and pollen is released. These efforts were not always successful and accounts of ring barking episodes on moonlight nights abound. apex. Scales slightly rounded at the apex and tending to overlap. Male cones never get woody, they are not persistent, and their growth is limited [3] . each with about 150-220 scales. ... Once hardened it can be harvested and, similar to other Agathis … Malecones cylindrical, 3-6 cm long by 1 cm wide, on a stout peduncle 1 mm wide;sporophylls imbricate, margin weakly erose. This pendant is a stylised design inspired by a male Kauri cone from the famous New Zealand Kauri tree (Agathis australis) - an ancient species which grows to huge proportions & whose timber is prized for it's exquisite aesthetic grain patterning & rich golden honey colour. The position of the male cone in the fossil record is needed to interpret more about the evolutionary trend. It is among the most ancient trees in the world. Themain definingfeature of A. silbae is the male cone: male strobili are cylindrical, oblong, somewhat broadened on the upper half, coppery­brown to red­brown, with a pe­ duncle 3.5–4 mm (0.14–0.16 in) long. About the Architect Denny Gondo. Agathis, commonly known as kauri or dammara, is a genus of 22 species of evergreen tree.The genus is part of the ancient conifer family Araucariaceae, a group once widespread during the Jurassic and Cretaceous periods, but now largely restricted to the Southern Hemisphere except for a number of extant Malesian Agathis. Pollen cones 37–55 In contrast, young trees are normally conical in shape, forming a more rounded or irregularly shaped crown as they achieve maturity. The Agathis Golf Residence The embodiment of vast landscapes with classical elegance in one harmony. Usually it is the builder, not the wood that makes a poor guitar. (1823) is an evergreen monoecious tree with erect trunk, cylindrical, up to about 50 m tall and of 1,8 m of diameter in the old specimens in nature, with initially smooth bark, then scaly, of reddish grey colour, exuding a whitish resin. The pollen cone is stiff, dense, cylindrical, and solitary; usually being found in the leaf axils. A fallen bisexual cone of Queensland kauri (Agathis broumii [Lemaire] 1. Type: Hyland 5776, Bellenden Ker Range, Jan. 1972, Holotypus BRI. Photo about Closeup of Agathis australis cone and leaves. The male cone is shown to have most of the taxonomically useful variation, and this confirms the findings of two partial revisions centred on … They mature around sixteen months … Plant usually monoecious, male and female cones on a single plant. Leaflets are narrow, linear with mucronate or acuminate apex. Cotyledons lanceolate, a number of +/- parallel veins run from base to apex. Plant usually monoecious, male and female cones on a single plant. The female cones are also round and ovoid, but they are compact and symmetrical. The genus is part of the ancient conifer family Araucariaceae, a group once widespread during the Jurassic and Cretaceous periods, but now largely restricted to the Southern Hemisphere except for a number of extant Malesian Agathis. Male pine cones are … Agathis, commonly known as kauri or dammar, is a relatively small genus of 21 species of evergreen tree. Distribution and Ecology. Male pine cones are usually yellowish because of the pollen dust. 1988. Themain definingfeature of A. silbae is the male cone: male strobili are cylindrical, oblong, somewhat broadened on the upper half, coppery­brown to red­brown, with a pe­ duncle 3.5–4 mm (0.14–0.16 in) long. The male pine cone, or microsporangiate strobilus, do not last as long as their female counterparts. The fruit are a round to egg-shaped cone, comparable in size to an orange and are either female or male on the same tree. Male strobili cylindrical, to 4 cm long by 10 mm wide, on a peduncle to 6 mm long; scale apices round. The leaves reach about 1 metre in length. The female cone is larger, more spherical in shape & is … Fruit and seed description Fruit: mature seed cones oval, 9-10.5 cm x 7.5-9.5 cm, seed bracts roughly obtriangular with a small projection near the base on one side. Similar species: The smooth bark, large male strobili with 600-1300 scales, and large cones with 340-440 scales distinguish this species from others of Agathis (Boland et al. By then the Forestry Department had taken a harder line and refused to allow logging of trees suspected of being victims of poisoning. Has separate male and female reproductive parts on the same tree (monoecious). CC-BY Australian Tropical Herbarium unless otherwise indicated in the images. nesophila Whitmore (1980) – Synonym: Agathis spathulata de Laub. The stands in the Danbulla State Forest area were particularly sought after because of their timber potential. Araucaria rulei). The leaves have parallel veins, not branching veins like those of angiosperms. A. robusta subsp. Various species of kauri give diverse resins such as kauri gum. Seedlings. The wood is commonly used in the manufacture of guitars and ukuleles due to its low density and relatively low price of production. Male cones and microsporophylls Whitmore (1980) stated that for A. flavescens, the size of the male cone is c. 4 by 1 cm while that for A. borneensis is 5–9 by 2–4 cm.

Male cones of 0,9-1,3 cm of diameter with rhombic microsporophylls. De Laubenfels (1988) gave the size of the male cones of A. flavescens as 2–3.5 by 8–9 cm and A. borneensis as 4–7 by 2–2.5 cm. Only female cones produce seed, which are winged and get carried on the wind after they are released. Branches horizontal or (when large) turning irregularly upward, leaving circular scars on the trunk after they fall. (1988). Moore ex F. Muell. The Agathis dammara (Lamb.) Coniferales. Endemic to Queensland, widespread in NEQ with another occurrence in the south-eastern corner of Queensland but absent from coastal central Queensland. The seed-cone scales 1 ovuled. The seed of Agathis is free from the scale, usually having only one well-developed wing. Bark Dark Brown or Light Green, Scaly or Smooth. Bark brown to grey, smooth, except for scattered flakes. In spring, male and female cones appear in the same tree (although young trees tend to be one-gendered at first). Cones usually less than 6 cm diam. The female seed cones usually develop on short lateral branchlets, maturing after two years. A. spathulata de Laubenfels 1988, type Papua New Guinea, Morobe, Wau, Middle Creek. The crown is dense, but often small in forest-grown trees, becoming more elongate when trees grow in the open. Agathis is monoecious. Stomata of Agathis are obliquely and/or perpendicularly oriented to the long axis of the leaf (Stockey and Atkinson, 1993) and those of Wollemia have not been Agathis is monoecious.

Male cones of up to 0,9 cm of diameter and almost triangular microsporophylls. The presence of the species triggered the construction of access roads to a number of North Queensland localities, e.g. Many Agathis species produce seed cones well before pollen cones appear, promoting cross-fertilization. It was female at the base and male at the tip (Fig. The timber is generally straight-grained and of fine quality with an exceptional strength-to-weight ratio and rot resistance, making it ideal for yacht hull construction. Seed germination time 5 to 7 days. AGATHIS robusta. Stem completely lacking buttresses. The branch structure is often horizontal or, when larger, ascending. Poir. The male and female cones are usually found on the same tree. It is a palm­ like tree. Male cones 20-50 mm long, stout, cylindrical, female cones globose 50-75 mm diam., cone-scales (carpidia) deciduous, at first broad but then gradually narrowing toward base, bearing one ovule per scale. 11.55D) or pollen sacs , varying from 8-15 in Araucaria and 5-15 in Agathis. Evergreen trees, usually monoecious, very large, with clear straight boles beneath a globular crown (young trees conical). P. 337–453 in Flora Malesiana, Series I, Vol. Fruit. Figure 4 shows the evolutionary trend in stomatal orientation. Usually monoecious. The male and female cones are usually found on the same tree. Seeds ellipsoid, 13 mm long by 6 mm wide, wing to 12 mm long on one side . The short pollen cones help distinguish this species from related Agathis species. Male cones less than 3 cm long, +/- sessile. each with about 90-150 scales. The last significant stand of Agathis robusta to be logged was on the Windsor Tableland and this was exploited in the 1970's and 1980's. Scales somewhat flattened at the apex and fitting together in the cone like honeycomb. Scales about 3.4-3.9-4.1-4.6 cm. Examination of several thousand other fallen male cones from 25 trees failed to turn up another that was in any way anomalous. There are 87- 152 scales in one cone, and, in a good season, 88-90 filled seeds per cone. nesophila Whitmore 1980, syn. Male cone size varies greatly from 2 mm in Juniperus communis up to 24 cm in Araucaria rulei [10] . 2.

There are two subspecies, distinguished by distribution and by pollen cone morphology: 1. The 4 to 6 inch tall rounded seed cones, held erect in the high branches, are initially green and mature to brown when they begin falling apart while they are still held on the tree. Wood specific gravity 0.48. 1860; type location Australia, Cairns, Wide Bay. The female cones are globe shaped, whilst male cones are more cylindrical measuring up to 5cm in length; and each brown, winged seed is attached to a triangular cone scale on the cone. In contrast, young trees are normally conical in shape, forming a more rounded or irregularly shaped crown as they achieve maturity.[3]. The seed cones usually shatter on the tree at maturity. Agathis, commonly known as kauri or dammara, is a genus of 22 species of evergreen tree. Altitudinal range in NEQ from near sea level to 1100 m. A characteristic tree of drier rain forest where other tree species experience difficulty in attaining large dimensions. the larger female cones (9-15 cm long and 8-10.5 cm wide) contain numerous densely packed seed-bearing scales. 1985). Adult leaves are opposite, elliptical to linear, very leathery and quite thick. Cones more than 6 cm diam. Many low priced poorly constructed guitars use Agathis wood as it is inexpensive, easy to attain, and easy to work with. Dordrecht: Kluwer Academic. Male (pollen) cones are cylindrical, 2-5 cm long and female (seed) cones are woody, globose, 8-10 cm thick. These accounts appear to be based on fact and as a result the Forestry Department was forced to allow the logging of trees which would otherwise die and rot in the forest. I sometimes receive questions about the cone and seed of kauri Agathis australis.There seems to be confusion about exactly what are the seeds. Male cones consist of a central axis with several sporangiophores (microsporophylls), each with one or multiple microsporangia releasing pollen at maturity. Male cones of A. macrophylla are elliptical and measure roughly 2-5 cm long at pollen shed. 9.6% of total fossils collected to date at PL‐2. these cones disintegrate when fully mature to release their winged seeds. Female (seed) cones are globular, 8-13 cm across, and are borne on short woody stalks. the male cones are cylindrical (4-10 cm long and 7-15 mm wide) and made up of hundreds of tiny spore-bearing structures. Stairs carved into an ancient kauri trunk (Ancient Kauri Museum, Awanui, near Kaitaia, Northland, New Zealand) Gum from a kauri tree, sold in Kauri Museum, New Zealand 6. This was the most common species of the Kauri Pine in North Queensland and one of the first stands to be exploited was in the Barron River catchment. Cause et al. Agathis can be a fine tone wood. The short pollen cones help distinguish this species from related Agathis species. Stomata of Agathis are &liquely and/or perpendicularly oriented to the long axis of the leaf (Stockey and Atkinson, 1993) and those of Wollemia have not been observed. The Pacific kauri (Agathis macrophylla) is a gymnosperm, and can become a tall tree, growing up to 40 m in height, with a trunk up to 3 m in diameter. Exudate slow and meagre. Seeds ovoid, compressed, margins winged. The male cone produces pollen and the female bears seeds. Cotyledons lanceolate with a number of veins arising at the same point at the base and continuing +/- parallel to the apex.

The juvenile leaves in all species are larger than the adult, more or less acute, varying among the species from ovate to lanceolate. The bark is smooth and light grey to grey-brown, usually peeling into irregular flakes that become thicker on more mature trees. Flowers colors: White Pot Size: 100lt, 200lt, 400lt The total collection of the new Agathis species comprises more than 150 leaf specimens, 29 male cones, 17 ovuliferous complexes, and 9 winged seeds, such that Agathis fossils represent ca. Young leaves are often a coppery-red, contrasting markedly with the usually green or glaucous-green foliage of the previous season. apex.

Accounts of poisoning persisted right up to until the 1950's but are harder to substantiate. Cataphylls are produced above the cotyledons and after lateral shoots are produced. [1][2], Mature kauri trees have characteristically large trunks, forming a trunk with little or no branching below the crown. The bract-scales extensively fused to the seed-cone scales in mature cones (though in Araucaria the tip is conspicuously free, constituting a “ligule”). They are normally oval or globe shaped. The male (pollen) cones are cylindrical, 5–10 cm long and 1-1.5 cm thick." Female cone subglobose, on a shortpeduncle, 6 cm long by 6-8 cm wide, glaucous-green, scales 1.8 cm long with ashort mucronate umbo (1). Description. Male cone is ovoid oblong. The male pine cone, or microsporangiate strobilus, do not last as long as their female counterparts. Fruit. Every spring, the pollen from the male pine cones are released into the air where they may eventually land on a scale on the female cone. There are 87- 152 scales in one cone, and, in a good season, 88-90 filled seeds per cone. The position of the male cone in the fossil record is needed to intemret more about the evolutionary trend. Cycas circinalis, a species endemic to India was the first cycad species to be described and was the type of the generic name, Cycas category. The male (pollen) cones are narrow reddish brown and cylindrical, 2 to 3 inches in length and erect when held on the tree but curled slightly when dropped to the ground. Copyright CSIRO. The genus is part of the ancient conifer family Araucariaceae, a group once widespread during the Jurassic and Cretaceous periods, but now largely restricted to the Southern Hemisphere except for a number of extant Malesian Agathis. (1978) Brunonia1(3): 109. The male cones are well-developed and reach up to 25cm or even more in some species (e.g. H.
