224 WILSON EXPEDITION TO CHINA 



loriim minora, 2.5-6 cm. longa et 6-3.2 cm, lata, v. ad 7.3 longa et 

 ad 3.5 cm. lata, supra viridia, fere glaberrima, subtus vix pallidiora, 

 breviter hirtella praesertim ad costam et nervos prominentes, nervis 

 utrinque 7-9 satis arcuatis; petioli tantum 1-2 mm. longi, puberuli. 

 Inflorescentia axillaris, pauciflora, puberula, pedunculo nudo brevis- 

 simo suffulta; flores nondum visi. Fructus ad 9 :4 mm. magnus, rubro- 

 nigrescens, unilocularis. 



Western Hupeh: Fang Hsien, thickets, alt. 1000-1600 m., July 

 1907 (No. 3389, type). Kiangsi: Kiukiang, 50 m., abundant on 

 plain, July 27, 1907 (No. 1515; bush 1.5-5 m. tall, fruit orange). 



The Kiukiang specimen differs in its obovate-oblong leaves, which measure 

 up to 9:3.4 cm. The older branchlets are brownish. The fruits contain only one 

 seed. Certainly this species is very closely related to R. franguloides Weber- 

 bauer, but differs in the size and shape of the leaves. I have only seen fruiting 

 specimens, and further investigation is needed to determine the real value of this 

 species. It has the same light colored bases of the stipules as R. franguloides. 

 The type of that species seems to be entirely absent from China, while it is abund- 

 ant in southern Korea. A specimen before me collected by Jelinek during the 

 Novara expedition near Shanghai probably belongs to R. obovalis.
