ASCLEPIADACEAE. — DREGEA 353 
m., May 24, 1908 (No. 2245; climber 1.25-1.50 m. tall). Yunnan: 
between Yung-peh-ting and Tai-nao-ko, climbing on shrubs and 
creeping on the ground, alt. about 2400 m., July 3, 1914, C. Schneider 
(No. 1730; flowers white with violet markings, semiscandent shrub up 
to 2 m.). 
The plant collected by me in Yunnan (No. 1730) is very similar to Wilson's No. 
2245, both having small leaves from 2.5 to 3.5 cm. in length and 2 to 3.5 cm. in width, 
but there is scarcely any other difference on which a variety could be based. Pos- 
sibly, however, the fruits are somewhat different. The ripe follicles before me of 
Wilson's No. 282* are up to 7 cm. long and 1.8 cm. broad at the base and are long- 
acuminate at the apex. The seeds are about 11 mm. long and bear a coma of about 
the same length (12-13 mm.). The shape of the calyx-lobes, the amount of the pu- 
bescence on the leaves and inflorescence and other details seem to be rather variable. 
I also collected specimens in southern Szech'uan in the district of Kuapie, of 
which I have only a small flowering piece béfore me which is very similar to the fol- 
lowing species, but as far as I can see from my notes the color of the flowers is the 
Same as that given for No. 1730.
