94 141. proscOREACEJE.— 142. ROXBURGHIACEE. 
This differs from D. japonica, Thunb., in its alternate leaves, 
and from D. doryophora, Hance, in its solitary male spikes. 
" Creeper, with dark red flowers and green fruit, growing many 
feet in length. The root is eaten in winter. The local name is 
‘ Hjang Chiang,’ i. e. yellow ginger.”—A. Henry. 
16. Dioscorea sp. 
Corea: Chemulpo (Carles, 178!). Herb. Kew. 
This is probably a new species, but the material is insufficient 
for specific description. The lower leaves are verticillate, with 
slender petioles as long as the cordate acute laminz. The male 
spikes are solitary in the axils of the alternate upper leaves. 
17. Dioscorea sp. 
Huren: Tunghu (A4. Henry, 6419!), Changyang (A. Henry, 
7501!) Nanto (A. Henry, 2666! 4486!); SzkcHvEN: North 
Wushan (4. Henry, 7103!). Herb. Kew. 
Resembling D. pentaphylla, Linn., and D. tomentosa, Linn., 
but not determinable, the specimens bearing leaves and very 
young fruit only.

1. Stemona acuta, C. H. Wright, in Journ. Linn. Soc., Bot. 
xxxii. (1896) p. 493. 
Kwanetrune (Ford, 283!). Herb. Kew. 
Differs from Stemona japonica, Franch. & Savat., in baving 
very acute leaves with cordate bases, and in the peduncles not 
being adnate to the petiole. 
2. Stemona erecta, C. H. Wright, in Kew Bulletin (1895), 
p. 117; Hook. Je, Pl. t. 2389; Journ. Linn. Soc., Bot. xxxii. 
(1896) p. 493. 
Anwuet: Nanking (Faber, 1541!). Herb. Kew. 
A species with erect stems and verticillate leaves, somewhat 
resembling Stemona sessilifolia, Miq., figured in the ‘Somoku 
Zusetsu,’ vol. ii. t. 55, but with more flowers on shorter pedicels. 
The anthers are appendiculate and the ovules erect, as in the 
other species of Stemona,
