origin, though believed to be of the Kumaon Himalaya, nothing is 
nown. 
A. racemosa, Munro (which form is not stated), was reported by 
Mr. W. J. Bean inthe Kew Bulletin for 1907, p. 230, to have flowered 
in the Temperate House at Kew in 1899, but specimens are 
apparently not in the Herbarium. 
I have come to the conclusion that the suspicion which I held 
when writing the ‘Bambuseae, and the ‘Manual of Indian 
Timbers’ and which Brandis so strongly confirmed, is well founded, 
and that the two forms of A. ra 
different species. he high-level form is clearly the one whose 
called by Hooker A. spathacea and A. spathiflora. But it is not 
A, spathiflora, Trin. ‘That is a well-known and distinct species of 
the WW cola Himalaya, so that a new name has to be found, and so 
I propose to call it A. Malng. The descriptions of the two 
species will now have to be revised, and I have consequently drawn 
up the following : |
