Afrocarpus
''Afrocarpus'' is a genus of conifers of the family Podocarpaceae. Two to six species are recognized. They are evergreen trees native to Africa. ''Afrocarpus'' was designated a genus in 1989, when several species formerly classified in '' Podocarpus'' and '' Nageia'' were reclassified.Christopher N. Page. 1989. "New and maintained genera in the conifer families Podocarpaceae and Pinaceae". ''Notes of the Royal Botanical Garden Edinburgh'' 45(2): 377-395. Taxonomy ''Afrocarpus gaussenii'' was based on a single specimen of a cultivated individual of ''Afrocarpus falcatus'' in Madagascar. Its distinctive features might have resulted from the conditions of its cultivation. No species of ''Afrocarpus'' is known to be native to Madagascar.James E. Eckenwalder. 2009. ''Conifers of the World''. Timber Press: Portland, OR, USA. . In a recent treatment of ''Afrocarpus'', only two species were recognized; ''A. dawei'', ''A. gracilior'', and ''A. usambarensis'' were sunk into ''A. falcatu ...

Afrocarpus Gracilior
''Afrocarpus gracilior'' (syn. ''Podocarpus gracilior'') is a species of coniferous tree in the family Podocarpaceae known as benet in Marakwet and East African yellowwood, African fern tree, or bastard yellowwood in English It is native to eastern Africa, in Ethiopia, Kenya, Tanzania, and Uganda, in Afromontane habitats. This is a common species found in many types of tropical mountain forest habitat. It is a dominant species in some areas. Nevertheless, it may be in slow decline due to deforestation and logging. Description ''Afrocarpus gracilior'' is a medium-sized tree, growing 20–40 m tall, rarely to 50 m, with a trunk diameter of 50–80 cm. The leaves are spirally arranged, lanceolate, 2–6 cm long and 3–5 mm broad on mature trees, larger, to long and 6 mm broad on vigorous young trees. The seed cones are highly modified, with a single diameter seed with a thin fleshy coating borne on a short peduncle. The mature seed is purple, and is di ...

Nageia
''Nageia'' is a genus of conifers belonging to the podocarp family Podocarpaceae.Christopher N. Page. 1990. "Podocarpaceae" pages 332-346. In: Klaus Kubitzki (general editor); Karl U. Kramer and Peter S. Green (volume editors) ''The Families and Genera of Vascular Plants'' volume I. Springer-Verlag: Berlin;Heidelberg, Germany. ''Nageia'' includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species.James E. Eckenwalder. 2009. ''Conifers of the World''. Timber Press: Portland, OR, USA. . Some authors consider ''Nageia formosensis'' to be a separate species from ''Nageia nagi'', thus recognizing six species. The podocarp genera have been reshuffled by various botanists. Most recently, several species formerly classed as ''Nageia'' were moved to the new genus ''Retrophyllum'', while ''Nageia falcata'' and ''Nageia mannii'' were moved to the new genus ''Afrocarpus''.

Afrocarpus Dawei
''Afrocarpus dawei'' is a species of conifer in the family Podocarpaceae. It is native to Africa, where it occurs in the Democratic Republic of the Congo, Tanzania, and Uganda. This species is a tree that grows in swampy forest habitat that is flooded in the rainy season. It is associated with ''Baikiaea insignis'' and '' Mimusops'' species. ''A. dawei'' is found in the Minziro Forest of Tanzania and the adjacent Sango Bay forests of Uganda, located west of Lake Victoria. The Kagera River sustains swamp forests and a high groundwater table that supports evergreen lowland forests.Kamukala, G. L., and S. A. Crafter, eds. (1993). "Wetlands of Tanzania: Proceedings of a Seminar on the Wetlands of Tanzania, Morogoro, Tanzania, 27–29 November 1991". Volume 10 of The IUCN Wetlands Programme. IUCN, 1993. This tree is valuable as timber because it grows a long trunk without many branches. It is likely overharvested, one reason that it is considered to be a near-threatened speci ...

Afrocarpus Mannii
''Afrocarpus mannii'' is an evergreen coniferous tree native to the Afromontane forests of São Tomé Island in the Gulf of Guinea, growing at altitudes of 1,300 m up to the summit at 2,024 m. It was formerly classified as ''Podocarpus mannii''. It is a small tree, growing 10–15 m tall. The leaves are spirally arranged, lanceolate, 6–8 cm long on mature trees, larger, to 15 cm long and 2 cm broad, on vigorous young trees. The seed cones are highly modified, with a single 2 cm diameter seed with a thin fleshy coating borne on a short peduncle. The pollen Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametop ... cones are 1.5-2.5 cm long, solitary or in pairs on a short stem.

Podocarpaceae
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 19 genera if '' Phyllocladus'' is included and '' Manoao'' and '' Sundacarpus'' are recognized. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and '' Nageia'' into southern China and southern India. Two genera also occur in sub-Saharan Africa, the widespread ''Podocarpus'' and the endemic ''Afrocarpus''. '' Parasitaxus usta'' is ...

Podocarpus
''Podocarpus'' () is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. The name comes from Greek πούς (poús, “foot”) + καρπός (karpós, “fruit”). ''Podocarpus'' species are evergreen shrubs or trees, usually from tall, known to reach at times. The cones have two to five fused cone scales, which form a fleshy, berry-like, brightly coloured receptacle at maturity. The fleshy cones attract birds, which then eat the cones and disperse the seeds in their droppings. About 97 to 107 species are placed in the genus depending on the circumscription of the species.Earle, Chris J.''Podocarpus''.The Gymnosperm Database. 2013. Species are cultivated as ornamental plants for parks and large gardens. The cultivar 'County Park Fire' has won the Royal Horticultural Society's Award of Garden Merit. Names and etymology Common names for various species include "yellowwood" and "pine", as in the plum pine ('' Podoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
