Agathis kinabaluensis is a plant of the family (Araucariaceae ). It is endemic to Mount Kinabalu and possibly on Mount Murud on the island of Borneo.
Agathis kinabaluensis grows as a evergreen tree that can reach heights of growth of up to 36 meters. The numerous lenticels having Stammborke is dark brown and stained the inner bark reddish. Young trees have smooth bark that is grainy with age and peeling off in irregular-shaped plates. The resin is white.
Young leaves are at a short petiole and a length of up to 9 centimeters and a width of about 4.4 centimeters spherical shaped. They have a pointed tip. Older leaves are also available on a short petiole and are at a length of 4 to 7 centimeters and a width of 1.8 to 3.2 centimeters also spherical shaped. They have a pointed or blunt tip. The lower leaf surface is not colored blue-green.
The male cones are on an approximately 0.4 -centimeter-long stem and are at a length of 2-3 cm and a thickness of about 0.9 centimeters cylindrically shaped. The female cones are up to 11 inches long and about 8 inches thick. They consist of triangular shaped cone scales. The seeds have a about 2 millimeters long, pointed projection, which opposes the two wings.
Distribution and location
The natural range of Agathis kinabaluensis located in Malaysia. There she came only on Mount Kinabalu in Sabah on Borneo before the province. A second possible occurrence on Mount Murud in Sarawak was identified in 1988 by David John de Laubenfels in the flora Malesiana as a population of Agathis orbicula.
Agathis kinabaluensis thrives at altitudes from 1500 to 2400 meters. It grows in higher mountainous forests, lower elevation forests with moss, and in subalpine bushes especially on nutrient- poor soils that developed on granite, sandstone or ultramafitite.
Agathis kinabaluensis is classified as " critically endangered " in the IUCN Red List. The main risk is why the low stock size is named along with the limited area of distribution. Likewise, place between the two populations, provided that the population is attributed to the mountain Murud of the way that the separate geographical location no genetic exchange takes place. The total herd is declining.
Agathis kinabaluensis is allocated within the genus of kauri trees ( Agathis ) of section Agathis.
