Dacrycarpus expansus De Laub.

Species

Gymnosperms > Cupressales > Podocarpaceae > Dacrycarpus

Characteristics

Tree 9-25(-30) m tall, 22-58 cm diam. Leaves of primary shoots on young plants nearly imbricate but on older plants spreading and then curved forwards. Leaves of juvenile foliage shoots distichous, nearly linear, soon losing the distichous habit as the tree matures. Leaves on older trees eventually becoming wider than thick but distinctly keeled on the upper and lower surfaces, spreading but the upper half curving forwards, uniform in size along the shoot, tapering slightly, 1.5-3 by 0.4-0.8 mm or a little larger on younger trees. Involucral leaves loosely surrounding the young fertile structure but covering only the receptacle of the mature seed with its covering, which is c. 3-3.5 mm long.

Environment

More
Locally common or even in pure stands (e.g. at Wabag), or co-dominant, sometimes emergent, often in disturbed situations, e.g. on edges of treefern grassland, 1300-2750 m.
