A species of the Irroratum Series gathered by Cooper 
in Bhutan. Its alliance is with Rh. Kendrickii, Nutt. and with 
Rh. papillatum, Balf. f. et Cooper. Kh. papillatum is likest to 
it but may be separated by the leaf-shape, to careful minute ob- 
servation by the absence of epidermal papillae on the leaf under 
side and also of the large spread out hairs of indumentum, by the 
membranous larger calyx, by the much larger corolla, by the 
glabrous stamens, by the sparingly glandular and hairy ovary, 
by the glandular ‘aeyle: Rh. Kendrickii in addition to clothing 
of young stems and the leaf-form differences has almost glabrous 
pedicels, calyx of 5 fleshy lobes, corolla crimson unblotched only 
3 em. long, stamens only 2.5 cm. long, ovary glabrous er most 
sparingly sebaceous floccose, style glabrous, narrower stigma. 
I should like to have made out that one of the plants*t have 
described here under the names of Rh. papillatum and Rh. epapil- 
latum was Nuttall’s Rh. Shepherdi from Bhutan of which no wild 
specimens are known but the ovary which is said to be quite 
_. glabrous in Rh. Shepherdi separates it. Rh. Shepherds is I 
think clearly one of the Irroratum Series.
