298 SERTULUM CHINENSE ALTERUM. 
calyx, ete., not so glandular, and column of styles less exserted.” Tt 
differs also, as will be seen by the above character, drawn up from 
very good materials in my herbarium, in the very small flowers,—no 
larger than those of the common South Chinese R. Brunonis,—and 
especially in the entirely free setaceous stipules, an important cha- 
racter in this genus, and by which it is, I believe, distinguished from 
all its European congeners. 
I may take this opportunity of stating that I believe there is no 
ground for regarding R. multiflora, Thunb., as a native of Hongkong. 
I have never found or seen South Chinese specimens myself; and 
Mr. Bentham, who incladed it in the ‘Flora Hongkongensis,’ has 
since informed me that he almost doubts Mr. Hinds’s specimen be- 
longing to this species, and that my own name was quoted on the 
authority of Dr, Seemann’s determination in the ‘Botany of the 
Herald’s Voyage.’ I have now before me an original specimen of the 
plant left with Dr. Seemann for that work, but it is unfortunately only 
in fruit; and, being labelled ** Hongkong "' simply, and collected about 
twenty years ago, I cannot give any account of its exact origin. It is, 
however, indubitably altogether different from Thunberg’s species, of 
which I possess a fine wild Japanese specimen, gathered by Maxi- 
mowicz, and, from the small lanceolate leaflets pubescent beneath, pea- 
like fruit, and deciduous stipules, I am inclined to suspect it may be 
referable to R. microcarpa, Lindl.; but, in the absence of flowers, it 
is impossible to feel any great certainty as to its affinity.
