N.E. Upper Burma. Maguchi Pass. Alt. 11-12,000 ft A 
broad spreading bush of 2-4 ft. abundant in the upper alpine 
region of the Maguchi Pass but seen nowhere else. Flowers 
variable in many shades ,of salmon and scarlet. Leaf reverse 
usually white but often of a dirty dark ash colour. Pedicels 
glandular. Fleshy corolloid calyx-process very conspicuous in 
the same colour as the flowers. This is no true calyx however 
since when the corolla falls this also after lingering a little comes 
off too in separate portions like deciduous petals. See also Farrer 
1669, 1683. Rh. euchroo valde affine sed basi cupulari inter alia 
distinguendum. Farrer No. 1775. July 31, 1920. 
true member of the Sanguineum Series and of the phylum of. 
Rh. sanguineum itself. Indeed Rh. sanguineum seems to be its 
nearest ally but may be distinguished by its crustaceous unistrate 
indumentum ; its floccose non-glandular indumentum on the pedi- 
cels; its much smaller reflexing calyx which never forms the 
conspicuous collar as it does in Rh. torquatum thereby giving its 
name; its glabrous not puberulous stamens; its ovary without 
glands and its always glabrous style. The style glandular at 
base is a peculiar feature here. 
Rh. euchrowm with which Mr Farrer seeks affinity is a very 
different plant and of the Series of Haematodes.
