by Franchet as R. sulphureum. Should this prove to be 
the case the latter name must disappear from our lists. 
The material for our plate has been derived from a plant 
raised from seed supplied by Mr. Forrest to Mr. J. C. 
Williams, Caerhays, who informs us that in spite of the 
affection of the plant for open situations in its native 
home, and though it is not a shade-loving species, it does 
not survive in this country if given a hot place in the 
sun. With partial shade it proves quite hardy. When 
in fruit, as Mr. Williams points out, it is exceedingly like 
R. glaucum, Hook. f., a native of Sikkim with rose-lilac 
flowers and acute calyx-lobes. It is also very nearly 
allied to &. campylogynum, Franch., a Yunnan species 
with pale rose-purple flowers.
