N.E. Upper Burma. Hpimaw Pass. Alt. 10,000 ft. Small 
bush with erect new shoots—their shaggy investiture ‘of white 
wool contrasting finely with the pure clear scarlet of the rather 
waxy flowers hanging below and almost all falling when found 
with Farrer No. 887 in ravine below the Pass. An odd parallel 
with Farrer No. 877 [Rh. phoenicodum] on the Chinese side. 
Also on Burmese side coming to its full and with a agi indu- 
mentum. R. Farrer No. 888. Mavlo. May 7,1 
Kingdon Ward collected in 1914 a plant in eek Upper 
Burma to which he attached the field ticket :— 
Forests below Feng-shin-hing Camp. Alt. 10,000 ft. Dwarf 
procumbent undershrub on a granitic scree facing South. 
Flowers scarlet. No. 1689. 20.6.14. 
Ward’s material was very slight and I hesitated about naming 
it. 1 could only assign it to the vicinity of Rh. euchroum. 1 
ain disposed to think that Werd’s plant of 1914 is this Rh. spera- 
bile-of which Mr Farrer got a splendid series of specimens 
enabling identification to be made without difficulty. There are 
some divergences in character however and if I place Ward’s No. 
1689 in the species it is with the caveat that further investigation 
is needed to confirm it. 
_ Rh. sperabile is a.near ally of Rh. euchroum but from Farrer’s 
specimens I judge Rh. sperabile is the finer plant. Separating 
characters are these :—Ri:. euchrowm has essentially a leaf wider 
above the middle—oblanceolate; here this is not so. “Then the 
stamens here are glabrous, in Rh. euchroum densely puberulous. 
From seed collected by Farrer there have been raised seedlings 
of Rh. sperabile at the Royal Botanic Garden, Edinburgh, and 
out of doubt elsewhere. It is one of the finest species he has
