G. Don (l.c.) gives Nepal as the habitat of R. formosum, but 
this is obviously a mistake. There are always 6 cells in the 
ovary and not 10 as stated by Don; perhaps he assumed there 
were 10 cells from Wallich having described the ovary as being 
“* to-furrowed.”’ 
Kurz (For. Fi. Burma, ii. 94) records R. formosum from 
Martaban, but his description seems to indicate a mixture of R. 
formosumand R. Veitchianum. I have seen only the latter species 
from this region, and it is extremely unlikely that R. formosum 
should occur there, as we know it only from the Khasia Hills. 
R. formosum is a favourite greenhouse shrub, with deliciously 
scented flowers. According to Millais (l.c.) it grows well and 
flowers freely out of doors in Cornwall, the West of Scotland, 
and in Guernsey, but does best even in those mild climates when 
given the shelter of a wall. There is a beautiful drawing by 
Fitch in the Botanical Magazine at t. 4457. 
37. Rhododendron burmanicum, Hutchinson in Kew 
Bull. 1914, 185. ; 
A branched shrub; one-year-old branchlets elongated, 
rusty-brown, lepidote, very densely so towards the top and 
strigose pilose here and there. Leaves crowded, numerous, 
oblanceolate to obovate, more or less shortly triangular at the 
apex with a knob-like mucro, cuneate at the base, 6-8 cm. 
long, 1.75—4 cm. broad, subcoriaceous, densely lepidote on both 
surfaces, the younger ones thinly ciliate especially towards the 
base, the scales both above and below much less than their 
own diameter apart, sometimes contiguous or slightly over- 
lapping, with a few larger ones scattered here and there, the 
epidermis shortly papillous between the scales; midrib im- 
pressed above, prominent below, lepidote; lateral nerves 9-11 
on each side of the midrib, diverging from it at an angle of 45° 
or more, arcuate, slender, slightly prominent below ; petioles 
stout, 0.5-I1 cm. long, grooved above, about 3 mm. thick, 
densely brown-lepidote, ciliate. Inflorescence terminal, 5
