[Roxburgh in his Flora Indica states, concerning the leaves, “ those of the root or loweripart of the culm are
much longer than the culm, tapering equally towards each end;” and as his observations were made on the
living plant, we suspect that Nees has taken his description from herbarium specimens only: at the same
rime. Rumphius’ figure can scarcely be our plant; perhaps it is a true species of Saccharum.]

Of this, which seems to be very common about Macao, we have not received the leaves. It appears to
be a remarkably tall plant, and the panicle is very similar to that of S. officinarum, from which, however, it
differs by the large and conspicuous valvelets of the fertile floret. 5. procerum differs by the upper valvelet
S. exaltatum, according to Roxburgh’s observations and drawing, has the upper valvelet of the bisexual
floret wanting in the pedicelled spikelet, but about equal to the other and acute in the sesile one ; according,
however, to N. v. Esenbeck's examination of what he considers the same plant, in Dr. Wight's herbarium,
it is the upper valvelet of the pedicelled (not the sessUe) spikelet which is equal and similar to the other,
while in the sessile one it is much shorter and obtuse. As we have not seen the leaves of the Chinese plant,
we are uncertain about its being the same as Roxburgh’s; and, besides, that author, in his drawing, represents
the upper valvelet much narrower and more acuminated than in our specimens, but probably his figure
may be inaccurate in that respect. The neuter valvelet and both those of the fertile florets are ciliated.
2. S. chinense ; paniculis ovatis contractis, ramis verticillatis subcompositis, gluma

[After having carefully examined the Chinese plant, and H. polystachyus R. et Sch., of which last N. ab
Esenbeck considers the Andropogon contortus of Roxburgh, and perhaps also of Linnæus, (hut not of
Brown’s Prodr. 1. p. 2 0 1 ,) to be a variety with solitary spikelets, we can see no good grounds for separating
them. Both have the peduncles elongated and often fascicled, each with one short-Ieaved sheath, the male
spikelets ciliated, and the leaves linear scabrous and more or less ciliated at the base : in the Chinese specimens
the hairs on the glumes and leaves are softer, and spring out of inconspicuous tubercles ; iu Dr. Wight’s
specimens of H. polystachyus the hairs are rigid, and arise from pretty large tubercles, but we can see no
other difference between the two ; if then our friend be correct in referring our Chinese plant to H. contortus,
we should be inclined to reunite to it H. polystacfnjus.
