338 MERRILL AND MERRITT. 
DISPORUM Salisb. 
l. Disporum luzoniense Merrill sp. nov. 
D. pullum Merr. in Philip. Journ, Sci. 1 (1906) Suppl. 182, non Salisb. 
Caulis glaber, usque ad 40 cm altus, strictus; foliis oblongo-ellipticis 
vel oblongo-ovatis, membranaceis, acuminatis, petiolatis, nervis usque ad 
9, transversalibus vix distinctis; floribus axillaribus, solitariis, cernuis, 
albis, intus purpureo-maculatis, perianthii segmentis circiter 1.5 cm 
longis, basi saccatis; staminibus quam perianthium multo brevioribus. 
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 em 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 
3 somewhat prominent, the transverse veinlets obscure; petioles 3 to 12 
ce mm long. Flowers axillary, solitary, nodding, the peduncles 1.5 to 2 
em long. Perianth 1.5 cm long, campanulate, white, marked with dull- 
P purple within, the segments 3 mm wide, 3-nerved, saccate at the base. 
Anthers 1.5 mm long. Ovary ovoid. Fruit dark-blue or black when 
mature, globose, fleshy, about 1 cm in diameter ; seeds obovoid, 4 mm long. 
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. 5942 Ramos, Merrill 4857: Province of Benguet, Mount Pulog, 
For. Bur. 16193 Curran, Merritt, & Zschokke; Pauai, Merrill 6619 (type), For. 
Bur. 14442 Darling, Bur. Sei. 8483 McGregor, Bur. Sci. 4816 Mearns. 
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. uniflorum 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.
