354 WILSON EXPEDITION TO CHINA 
curvatis retinaculo subaequilongis; ovaria minute pilosa, stigmatibus 
capitatis antheras vix v. paulo superantibus. Folliculi (an satis ma- 
turi?) angulo 180? divergentes, 6.5 em. longi et basim versus circiter 
1.3 em. crassi, versus apicem valde attenuati, leviter curvati, breviter 
et laxe villosuli, insigniter (apice excepto) subannulato-plicato-corrugati, 
in sicco cinereo-flavescentes; semina subobovato-oblonga, circiter 9- 
10 mm. longa, basi obtusa 4-5 mm. lata, valde compressa, apice 
coma sericea iis duplo longiore instructa. 
Western Szech'uan: Mao-chou, arid regions, alt. 1300-1900 m., 
June 1, 1908 (No. 1190 type; climber 1.5-3 m. tall, flowers yellowish); 
same locality, etc., August 1908 (No. 1190*; with fruits). Southern 
Szech'uan: Nanch'uan, A. von Rosthorn (No. 2351; with young 
fruits; No. 2350; with flowers). 
This species is very similar to D. sinensis Hemsley, but the fruits look dis- 
tinct, as they have numerous annular crest-like excrescences, while those of D. 
sinensis have indistinct and irregular longitudinal exerescences. The pubescence of 
the new species is even more dense than that of D. sinensis, especially on the under 
surface of the leaves. The specimens from Nanch'uan mentioned above seem to 
belong to D. corrugata according to a young fruit on No. 2351. It is difficult to 
decide from dried specimens whether the differences in the structure of the flowers 
are sufficient to distinguish the two species and even some of the forms of D. 
sinensis. The color of the flowers is described differently by different collectors. 
I suppose the flowers are creamy white marked with purplish or lilac spots which 
more or less or wholly disappear in drying.
