Description from specimens taken from clumps cultivated in 
the Bamboo Garden, Royal Botanic Gardens, Kew, in August 
1920 (by W. J. Bean and J. S. Gamble). By Mr. Wilson’s 
special wish the species is dedicated to his daughter, Muriel 
Wilson. 
This Bamboo was presented to Kew from the Arnold Arboretum 
in the autumn of 1913. A single plant came in a pot, and this 
was divided up into about half a dozen pieces, which were re- 
potted and grown for a few months in a greenhouse. They were 
then planted out in the collection of Bamboos near the Rhodo- 
dendron Dell where they have grown luxuriantly and promise to 
e as ornamental as any hardy species. They are at present 
(October 1920) about 8 ft. high forming dense masses of culms, 
the outer ones of which arch outwards towards the top and give 
the plants a very graceful appearance. In growth A. Murielae 
resembles A. nztida, Mitford, more closely than any other hardy 
species in cultivation, but the culms are stouter and the leaves 
Moreover, Mr. E. H. Wilson, who collected and first 
introduced it to cultivation, informs me that the old culms are 
rich yellow; in A. nitida they are purple-black. On the whole 
A. Murielae is a distinct and most attractive addition to hardy 
bamboos. W. J. Bean. 
LV.—NOTES ON THE BALSAMS OF CHITRAL 
AND THE KACHIN HILLS. 
By the late Masor S. M. Toprin, R.A., M.C. 
In a previous number (Kew Bull., 1918, 156), the bequest to 
announ lants i 
ced of a large collection of Indian 
accordance with the will of Major Toppin. The excellent set of 
Impatiens which it included, accompamed by typewritten descrip- 
tive notes by himself and coloured sketches was specially noted. 
These proved to be of great value and as they were almost ready 
for publication the following paper has been arranged with such 
few additions as were necessary by Mr. S. T. Dunn, B.A., 
Assistant for India in the Herbarium. e paper is followed 
by some extracts from Sir Joseph Hooker’s letters to Major 
Toppin on the subject of his Impatiens collections. 
FERTILIZATION OF BuRMESE IMPATIENS. 
For the purpose of discussing the fertilization of the Balsams 
found in Burma, I have divided the species up into three main 
groups according to the relative positions of the different portions 
of the flower— fe

other as to close the lip.
