Taxonomic notes

Description

"A tree up to [21 m] high, resembling L. plumosa, from which it differs chiefly in its smaller size, smaller leaves and cones, and in the four-sided character of the ultimate branchlets. In the juvenile phase, the facial leaves are about [1 mm] long and the lateral leaves about [3 mm] long; adult leaves are suhequal, in size about [2 mm] long, in shape triangular, acute and appressed. Male strobili about [2.5 mm] long, with 7-9 sporophylls. Cones ovoid, about [10 mm] long, the 4 scales each bearing a curved dorsal mucro. Seeds 2 (one to each fertile scale)" (4).

It is reduced to a bush at higher elevations, or in wet ground (4).
