“N.E. Burma : Chawchi Pass. Alt. 10,000 ft. This precisely 
echoes Farrer 1045 [Rh. calostrotum] in every way even to habit 
and habitat, but seems a quite distinct species with hairier nar- 
rower foliage and great magenta-crimson flowers usually solitary. 
1s range seems, in fact, to repeat Farrer 1045, Farrer 1046 
[Rh. myrtilloides] in two species, extraordinarily similar, yet 
distinct. Whereas Farrer 1046 and Farrer 1045 have twin 
flowers, for instance, Farrer 1690 and Farrer 1670 [Rh. charo- 
poeum] are 1-blossomed [No; both these run as frequently to 
pairs, July 22]. Cf. also 1683 [ Rh. chaetomallum]. Farrer No. 
1690. July 3, 1920.”
