constant): in the present instance the difference is so great, 
though there cannot be a question of the identity of species, 
that we feel ourselves, as it were, compelled to make it a variety. 
The corollas are nearly, if not quite, double the size of the native 
plant as seen by Dr Hooker, and instead of being of a uniform 
lilac-purple colour, they are of the most delicate white, tinged 
with red-rose colour. In all other respects the two plants 
perfectly agree. It is a native of wet rocky places (rarely in 
woods) of Sikkim-Himalaya, in the Lachen and Lachoong valleys; 
elevation g—Io,ooo feet. It may be expected to be hardy 
therefore ; and, indeed, we may observe, that young plants of 
nearly all our species from Sikkim-Himalaya have passed this 
winter in the open air, simply surrounded by a bank of eartha 
foot and a half high. R. Dalhousiae alone has failed in such a 
situation, and in many cases we know that it has equally 
failed under glass. R. ciliatum has been kept in a cool green- 
house, and has certainly the merit of being a ready flowerer, 
and that at a very early age.” 
Professor Balfour gives some interesting notes on the colour 
of the flowers of this species under various cultural conditions 
in his notes at the end of the description of R. Valentinanum 
(p. 48). 
: Mr Millais, in his book on Rhododendrons, lL.c., gives an 
interesting account of this species in cultivation, to which’ the 
reader may be referred for fuller details. He states that in 
Cornwall and the West of Scotland it grows as much as g ft. 
high and 16 ft. through. The species proves to be more hardy 
than most of the others from the Himalayas, and in gardens 
there is apparently considerable range in the colour of the 
flowers. Mr Millais describes them as “rich red in bud and 
opening to pale pink, pale reddish-purple or white, all fading 
to white after a few days.’’ He speaks very highly of this 
species as a garden plant, and gives what is known of its use 
in hybridisation. 
The following remarkable species, closely resembling R. cilia- 
tum, has turned up since this paper was completed. Professor 
Balfour very kindly allows the description to appear here :—
