Has. On the Gascherong hills in Bootan, at an elevation of about 5000 
feet; parasitic on Oaks, and accompanied by Thibaudias, a new spe- 
cies of arborescent Hydrangea, etc. 
A straggling shrub, 5-6 feet high. Young branches and petioles at 
first densely hairy. Leaves very thick and coriaceous, between £t 
inches long and 2-21 inches wide, acuminate, with a sharp longish 
point, and rounded at the base; the margin only, in adult leaves, 
thickly set with longish brown hairs, beneath thinly covered with small 
brown scales, just visible to the naked eye. Bud-scales smooth, brown, 
dilated and rounded, with a small point, and the margins with a sil- 
very ciliation. Corymb of seven or eight flowers (in the only spoom 
I have seen). Segments of the calyx large, nearly the third of an inch 
long, leafy, rigid, smooth and membranaceous, oval and obtuse. Cap- 
sule light brown, with a thick wrinkled epidermis, two-thirds of an inch 
long, oval and obtuse, five- but mostly six-celled. Seeds numerous, 
dark brown, subulate, and nearly without any margin. Leaves in young 
plants wholly hairy. 
` A fine and very distinct species, occurring at a lower elevation than 
most of the Bootan species. Where it grew however the thermometer 
fell at nights occasionally to the freezing-point. By the calyx and 
. other characters (in the absence of flowers), it appears to be allied to

7. RHODODENDRON EDGWORTHII ? 
This latter species is also an epiphytal shrub, differing from the 
plants figured in having usually two of the upper divisions of the calyx 
larger and dilated. Being, as yet, ignorant of the flower, we cannot 
tell whether any other differences may occur, worth notice. They both 
. grow in a region in which Oaks thrive. R. Dalhousie appears also to
