Dacrydium leptophyllum

(Wasscher) de Laub. 1988

Common names

Taxonomic notes

Syn: Podocarpus leptophylla Wasscher 1941; Dacrycarpus leptophylla (Wasscher) Gaussen 1974. "The original description expressed uncertainty between Dacrydium and Podocarpus sect. Dacrycarpus for this unique taxon, but unfortunately settled for the latter. The tiny leaves are typical for Dacrydium and the primary branches show no sign of the dimorphism which characterizes Dacrycarpus (de Laubenfels 1988).

Description

"Leaves diverging widely from the stem but sharply bent forward parallel to the stem or even directed inward, lanceolate, pungent, 1-1.5 mm long, 0.2-0.3 mm wide, 0.1 mm thick, strongly keeled on the dorsal side, flat or slightly concave on the axial side. Leaves on vigorous branches larger, up to 3 mm long and 0.6 mm wide. Fertile material unknown" (de Laubenfels 1988).

Distribution and Ecology

West New Guinea, known only from the top of Mt Goliath (4°32' S, 139°51' E), at 3000-3600 m elevation (de Laubenfels 1988).

The IUCN reports that this taxon is "vulnerable." The population is estimated to number fewer than 1000 mature individuals and suffers from a very restricted area of occupancy (typically less than 20 km2 or number of locations (typically five or fewer) such that it is prone to the effects of human activities or stochastic events within a very short time period in an uncertain future, and is thus capable of becoming Critically Endangered or even Extinct in a very short time period.
