Hab. in Nepalia, Buchanan; Bengalia tempore fer-

Branches pale brown, flexuose, covered with very 
soft down; prickles generally naked, with a long base, 
bright brown, pointing upwards, placed by pairs under 
the stipule, which are nearly distinct, downy, and di- 
vided at the margin into several capillary compound 
segments, here and there fringed with glands; on vi- 
gorous rootshoots they are united half way, and then 
the part which is disengaged frequently extends into a 
small pinnate leaf; petioles slender, downy, with a few 
small prickles; leaflets 3-9, elliptic lanceolate, obtuse, 
bluntly serrated, dull green, naked above, downy 
(rarely naked) and paler beneath. Flowers white, sub- 
solitary, surrounded by three or four approximated 
leaves; bractew pectinate, woolly, as are the short pe- 
duncle, globose tube of the calyx, and spreading entire 
sepals ; petals emarginate, longer than the last; disk 
long, large and thickened; styles villous, a little ex- 
serted. 
For an opportunity of examining spontaneous speci- 
mens of this new species I am indebted to Mr. Lam- 
bert; they were collected in Nepal by Dr. Buchanan, 
and from the ticket attached to them, probably in 
marshy situations. Of this however no mention is 
made by Dr. Roxburgh, by whom in his manuscript 
Flora Indica a detailed account of the species is given 
with the name here adopted. It has recently been im-
