(The plant which we have joined as var.A, to that described by Nees von Esenbeck, differs from it in no
respect except in the more branched inflorescence : the structure of the spikelets being identical in both. On the
other hand, we see few grounds for separating the more luxuriant or more perfect form, and which is by far
the most abundant in our collection, from A . montams, Roxb. ; Roxburgh, however, describes the leaves as
“ long aud narrow,” and figures even the uppermost one close to the panicle, and 6 or 8 inches long, while
in our plant it is very short and subulate ; Roxburgh, moreover, does say that the lower glume of the fertile
spikelet is channelled on the back, which could scarcely have escaped the notice of N. von Esenbeck.
Var. « has much the appearance of A . leptostachys, Wiglit and Am., (or A . saccharoides, Roxb., and
n. 890 of his drawings at the India House), but in that also the uppermost leaf is elongated and similar to
the lower ones, and the branches of the inflorescence seem constantly alternate, simple, and bearing a single
slender spike that is fully more than an inch and a half long. We have received both « and fi from Prof.
Henslow, under ». 50 of Mr. Vachell’s collection ; Mr. Millett has only sent the var. fi.]

[We fear that the difference between these varieties is not constant : we have observed on the same panicle
some glumes with four nerves, others where the middle pair had coalesced into one in the centre, and others
where the two lateral ones had merged into the margin; so that the glumes might be said to be either
2-, 3 ; or 4-nerved ; the smaller the specimen, the more decidedly were the glumes only 2-nerved.]
