rosissimis; petiolo 26 ad 32 cm longo, circiter 1 cm diametro, 
fere ad apicem vaginato; spatha coriacea, lanceolata, acuminata, 
circiter 18 cm longa; spadix sessilis, cylindricus, circiter 2 cm 
crassus. 
Ng Chi Leng, McClure 8714, December, 1921. Growing over 
large bowlders in ravines, altitude 600 meters. 
A species probably most closely allied to the Philippine R. 
monticola Engl. and Krause, but with smaller leaves, much 
slenderer petioles, and much shorter spathes. It differs from 
the Javan R. montana Schott in its larger leaves, which are 
distinctly cordate at the base, and larger spathes. 
LILIACEAE 
DISPORUM HAINANENSE sp nov. 
Circiter 70 cm alta, haud ramosa; foliis membranaceis, ellip- 
ticis, abrupte et tenuiter acute acuminatis, 7 ad 10 cm longis, 
3.5 ad 4.5 cm latis, nervis primariis 5; umbellis in axillis super- 
ioribus, brevissime (2 mm) pedunculatis, circiter 5-floris, pedi- 
cellis tenuibus, circiter 1.5 cm longis; floribus circiter 1 cm 
longis, perianthii segmentis oblongo-obovatis, abrupte breviter 
acuminatis, deorsum angustatis, basi leviter ventricosis, haud 
saccatis, margine ciliatis; filamentis 8 mm longis. 
Ng Chi Leng, McClure 8585, December, 1921. On cliffs, al- 
titude 800 meters, December 21, 1921, flowers yellow and maroon, 
fragrant. 
Although my specimen is unbranched, I do not hesitate in 
placing it in the genus Disporum. It is characterized otherwise 
by its small flowers, not exceeding 1 cm in length, and by its 
perianth-segments being narrowed below and slightly ventricose 
but not saccate or spurred. To be compared with the material 
from Lofaushan, Kwangtung Province, referred with doubt by 
Dunn and Tutcher, after Hemsley, to Disporwm leschenaultianum 
D. Don; it is certainly not Don’s species, whatever else it 
may be.
