RHAMNACEAE. — RHAMNUS 239 



1900 (Veitch Exped. Nos. 497, 497^); same locality, A. Henry (Nos. 

 1689, 3611, 3611% 3609, 4560, 3593^^). Szech'uan: Nan-ch'uan, A. 

 von Rosthorn (Nos. 2293, 2300). 



The type was sent by A. Henry from Hupeh, but unfortunately Hemsley cites 

 no number. The branchlets and leaves are alternate on all the specimens I have 

 seen. This species is apparently related to R. hypochrysus Schneider, from which 

 it can be at once distinguished by its longer petioles and the different serration 

 of the leaves.

 flowers yellowish, fruit black); Changlo Hsien, thickets, alt. 1300- 

 2000 m., November 1907 (No. 475, in part; bush 1-2.5 m., fruit black) ; 

 Fang Hsien, thickets, alt. 2000-2300 m., November 1907 (No. 618; 

 bush 2 m., fruit black); Ichang and neighbourhood, A. Henry (Nos. 

 3407% 3407, 1493, type). Western Szech'uan: Mt. Omei, June 

 1904 (Veitch Exped. No. 4779). 



Wilson's specimens differ a little from the type in their glabrous female flowers, 

 but otherwise the differences between them are not very obvious. The species 

 is certainly rather nearly related to R. parvifolms Bunge. The type was col- 

 lected in Hupeh by Dr. Henry (No. 1493). The female flowers have narrow 

 and acute sepals, no petals and only very reduced staminodes. The seeds which 

 are flatter or even concave on the inner surface are broader than the seeds I have 

 seen of R. parvifolius Bunge, which are obovate-oblong.
