Everything about Nageia totally explained
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. Six
species are recognized, with
N. formosensis recently split out from
N. nagi. The podocarp genera have been reshuffled by various botanists; most recently, several species formerly classed as
Nageia were moved to the new genus
Retrophyllum, and
N. falcata was 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 (
Araucariaceae). The leaves vary from 5-20 cm long and 2-6 cm broad. The
cones have several sterile and one (rarely two) fertile scales, each fertile scale with one
seed. Unlike
Podocarpus, the scales don't become fleshy, but the seed coat develops into a
drupe-like fleshy covering 1-2 cm diameter, which attracts
birds, which then disperse the seeds in their droppings.
Nageia can be found in the
tropical and subtropical moist broadleaf forests of
Asia and
Australasia, from
Assam in eastern
India across
Southeast Asia to southern
China and southern
Japan, and across
Malesia, from the
Malay peninsula across
Indonesia to
New Guinea and
New Britain. An outpost of
N. wallichiana is found in the
South Western Ghats montane rain forests of southern India, where it's thought to be a relatively recent colonist in biogeographical terms.
Nageia, like many podocarps, can usually be found scattered throughout the forest mixed with other trees, and is rarely if ever found growing in pure stands. The wood is yellowish, typical of podocarps, and a few species are locally important for timber.
