It is endemic ecology endemic to southern China , occurring in northern Guangdong , northern Guangxi , Hunan , Southwest Jiangxi and southern Zhejiang . Like other yews, it is a small Pinophyta coniferous shrub or small tree , reaching 2 5 m tall with reddish bark . The leaf leaves are lanceolate, flat, 1 2.6 cm long and 2 3 mm broad, dark green above, with two white stomata l bands below they are arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem. The conspicuous white stomatal bands on the harder, stiffer less soft leaves readily distinguish it from the yews in the genus Taxus . It is plant sexuality dioecious , with the male and female conifer cone cones on different trees. The female seed cones are very similar to those of Taxus species, but the aril is white when mature, not red they are 5 7 mm long and wide. The male pollen cones are globose, 3 4 mm diameter. It is grown as an ornamental plant in southern China and occasionally elsewhere.

Its classification has been disputed in the past, with some suggestions that it may be best placed in its own family the Austrotaxaceae or be related to the Podocarpaceae , but recent genetic evidence places it firmly in the Taxaceae , related to the other yews in the genera Taxus and Pseudotaxus . It is endemic ecology endemic to New Caledonia , occurring in the central and northern parts of the island on serpentine soil s at 300 1,350 m altitude. It is a Pinophyta coniferous shrub or small tree , reaching 5 20 m rarely 25 m tall with reddish bark . The leaf leaves are lanceolate, flat, 8 12 cm long up to 17 cm on young plants and 4 mm broad, dark green above, with two paler green stomata l bands below they are arranged spirally on the stem. The conifer cone seed cones are drupe like, 20 25 mm long, with a fleshy aril almost completely surrounding the single seed , but with the tip of the seed exposed. The male pollen cones are 10 15 mm long, slender. The markedly longer leaves and large seeds readily distinguish it from the yews in the genus Taxus .

File LocationZambia.svg thumb The Zambezian Cryptosepalum dry forests consists of two areas of thick forest in Southern Africa and is one of the largest areas of tropical evergreen forest in the world apart from those right on the equator. Location The forest are found on rolling hills of sandy soil drained by the Kabompo River of northern Barotseland in Western Zambia , with one area across the border in Angola . The climate is tropical savanna, with average annual temperature around 21 C. http www.nationalgeographic.com wildworld profiles terrestrial at at0203.html 1& 93 Flora Mainly the tall mukwe trees Crypotsepalum exfoliatum pseudotaxus and the dense undergrowth of creepers and mosses that lie underneath them. Fauna The forests are home to a variety of wildlife including ungulates such Yellow backed Duiker , Blue Duiker and their predator s, as well as other species such as bushpigs . The only two endemic species are a mammal Rosevear s Striped Grass Mouse , and a bird White chested Tinkerbird Pogoniulus makawai . However the latter has not been actually spotted since 1964 and may in fact be a variant of the common and widespread Yellow rumped Tinkerbird Pogoniulus bilineatus . The forests are particularly rich in birdlife with nearly 400 species found here including the Guttera edouardi kathleenae subspecies of the Crested Guineafowl , Olive Long tailed Cuckoo Cercococcyx olivinus , Ross s Turaco Musophaga rossae , Cabanis s Greenbul Phyllastrephus cabanisi , Purple throated Cuckoo shrike Campephaga quiscalina , Boulton s Batis Batis margaritae , African Crested flycatcher Trochocercus cyanomelas , Square tailed Drongo Dicrurus ludwigii , Black fronted Bushshrike Telophorus nigrifrons , Perrin s Bushshrike T. viridis , Olive Sunbird Nectarinia olivacea , Forest Weaver Ploceus bicolor and Black tailed Waxbill Estrilda perreini .

The male conifer cone cones are 2 5 mm long, and shed pollen in the early spring. The female cones are highly reduced, with just one ovuliferous scale and one seed. As the seed matures, the ovuliferous scale develops into a fleshy aril partly enclosing the seed. The mature aril is brightly coloured, soft, juicy and sweet, and is eaten by bird s which then disperse the hard seed undamaged in their droppings. However, the seeds are deadly poisonous to humans, containing the poisons Taxine and Taxol ref http www.nlm.nih.gov medlineplus ency article 002877.htm Yew Poisoning MedLine Plus Medical Encyclopedia ref .

It has been recognized as a natural floristic area since 1872 August Grisebach s volume Die Vegetation der Erde and later delineated by such geobotanists as Ludwig Diels , Adolf Engler as Temperate Eastern region , Ronald Good as Sino Japanese Region and Armen Takhtajan . The Eastern Asiatic Region is dominated by very old lineages of gymnosperm s and woody plant families and is thought to be the cradle of the Holarctic Kingdom Holarctic flora. Moreover, this floristic region wasn t significantly glaciated in the Pleistocene , and many relict Tertiary genera such as Metasequoia glyptostroboides , ancestors of which were once common throughout the Northern Hemisphere up to subpolar latitudes found refuge here.
