Stamina tria, antheris luteis. Stigmata purpurea. Glumæ scabræ, cum setis suis pallidæ. Folia rigidula,

hordeiformis; spiculis fructiferis florentibus erectis subsessilibus, valvulis flosculi æqualibus V. p atula;
spiculis fructiferis patentissimis pediceUatis, valvulis flosculi inæqualibus.
[Witii P . hordeiformis we are unacquainted. Between P . latifolia (for we are stili inclined to retain
that name instead of patula) and P . longijiora, there are some obvious differences in the foliage : in both
the leaves are of the same general shape ; but in P . latifolia they are waved, and have a cartilaginous
discoloured (in our specimens) margin, which is armed with rigid, close, sometimes bristle-bearing teeth, from
the base to near the apex ; in P . longiflora, they are flat or involute towards the apex, decidedly glaucous,
and the marçin toothed only near the base. In P . latifolia the sheaths are strongly striated ; in P . longiflo
ra , scarcely at all. In P . latifolia the leaves are scattered at equal distances on the lower half of the
culm ; in our specimens of P . longiflora they are crowded for about one-fourth from the root ; but as in
both the two upper leaves aie remote, we are disposed to regard the approximation of the lower ones as the
effect of a greater or less development of the whole plant.]

[Athough our friend has not sent the specific character, we presume he here means V. elongata, Trin.
unifl. p. 154, or Sporobolus elongatus. Brown : but our specimens do not altogether agree with Brown’s
observations, in as far as he states the branches of the panicle to be alternate and the lower ones distant;
whereas here they are more or less fascicled or verticillate, and the lower ones are not more remote than in
V. tenacissima ; the glumes are ovate, the upper one between twice and thrice, and the lower nearly four
times shorter than the floret. The leaves are convolute. On the whole, therefore, we do not see why our
plant ought not to be rather referred to V. tenacissima, Humb. and Kunth ; perhaps, however, as Trinius
says, V. elongata is too closely allied to it. In both, the branches of the panicle are floriferous from their
very base or nearly so.
