Nageia, genus Nageia(noun)
small genus of Asian evergreen trees having columnar crowns and distinguished by leaves lacking a midrib; eastern Asia including India and Philippines and New Guinea
Nageia is a genus of conifers belonging to the podocarp family Podocarpaceae. Nageia includes evergreen shrubs and trees, from one to 54 meters in height. A 2009 treatment of the genus recognized five species. 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. The species of Nageia are distinguished from other genera in the Podocarpaceae by their broad, flat sub-opposite leaves with no midrib, superficially similar to those of the unrelated Agathis. Nageia is the only genus in Podocarpaceae with multi-veined leaves. The leaves vary from 5–20 cm long and 2–6 cm broad. The cones have several sterile and one fertile scales, each fertile scale with one seed. Unlike Podocarpus, the scales do not become fleshy, but the seed coat develops into a drupe-like fleshy covering 1–2 cm in diameter, which attracts birds, which then disperse the seeds in their droppings.
