It seems to me that the only point in which this new genus 
differs from Schizostachyum as originally described is that the 
stamens are monadelphous instead of free. 
As this character is considered sufficient to separate Giganto- 
chloa from Bambusa, there is no reason why it should not be 
sufficient to separate Neohouzeaua from Schizostachyum, and 
perhaps some species described under the latter may also have 
to be transferred to the former. As a rough working key to 
the two genera and their neighbours, I suggest :— 
Palea 2-keeled, two keels close together - Cephalostachyum. 
Palea convolute, not keeled :-— 
Spikelets with several flowers - - - Teinostachyum. 
Spikelets 1-flowered :— 
Stamens monadelphous - - - Neohouzeaua. 
Stamens free . - - WSchizostachyum. 
The description of the flowers of N. Dullooa, which may be 
added to those given in the ‘ Bambusex’ at p. 101, and in the 
‘ Flora of British India,’ Vol. vii., p. 411, is as follows :— 
“Spikelets usually 2 together, slender, bracteate at the 
base; empty glumes 2-4, small, mucronate; flowering glume 
about 8-10 nerved; palea convolute, glabrous except near the 
apex, *7—'8 in. long, biaristate, the base sometimes with a free 
terminal rachilla often bearing rudiments of a terminal flower; 
stamens 6, monadelphous, the anthers -35 in. long, obtuse at 
apex, at length exsert; ovary elongate, glabrous, stigmas 3, 
short, red.” 
I now come to the question of T'einostachyum Helferi, of which 
Mr. Hole has sent me a number of ‘excellent specimens in all 
stages. The spikelets are much larger than those of NV. Dullooa 
and are 1-1-5 in. long, the palea is convolute with no trace of 
keels and biaristate, the stamens are monadelphous, so that it 
clearly must now be transferréd to Neohouzeaua and be known 
as N. Helferi Gamble n. comb. The following description may 
be added to those given in the ‘ Bambuseae’ and the ‘ Flora of 
British India.’ 
“ Heads of spikelets often large, even up to 2 in. in diam., 
though usually less. Spikelets usually 2 together, slender, 
‘strigosely hirsute; flowering glume ovate-lanceolate, long- 
mucronate, strigosely hirsute, -5-1 in. long, many-nerved; 
palea convolute, glabrous except at the tip, 1-25-1-5 in. long, 
biaristate, the: base sometimes with a free terminal rachilla ; 
stamens 6, monadelphous, the anthers *5--75 in. long, obtuse at 
apex, at length exsert ; ovary oblong, elongate, glabrous, stigmas 3, 
short, red; pericarp of caryopsis leathery, oblong, including 
the beak over 2 in. long.

Mr. K. F. R. Dickins and others in the Thandaung forests of the
