Rootstock stout, 5 to 8 mm in diameter. Stems solitary, erect, un- 
branched, stout, glabrous. Leaves 4 to 8 on the upper half of the stem, 
oblong-elliptic to oblong-ovate, membranaceous, 8 to 11 cm long, 3 to 
4.5 cm wide, base rounded or acute, apex prominently acuminate, acumen 
blunt; primary nerves 5 to 9, distinct, the secondary ones' also often

This species, previously confused with Disporum pullum Salisb., is represented 
by the following specimens, all from northern Luzon : District of Lepanto, Mount 
Data, Bur. Sci. 59 1$ Ramos, Merrill J/857 : Province of Benguet, Mount Pulog, 
For. Bur. 16193 Curran, Merritt, & Zschokke; Pauai, Merrill 6619 (type), For.

. It is confined to the region of the mossy forest, above an altitude of 2,000 m, 
and at Pauai it flowers in May and June. It is allied to Disporum pullum 
Salisb., and apparently also to D. utiiflorum Baker, but is distinct from both. 
It is well characterized by its unbranched stems, solitary, axillary, nodding 
flowers which are white, marked with dull-purple inside, and its stamens much 
shorter than the perianth.
