cum seta majori 9 lineas longis, minus divaricatis, turn glumis magis adhuc lenissimeque in setam acutatis pro 
longitudine angustioribus. Flosculus glumis triple brevior ; -valvula inferior membranacea, satis firma, 
trinervis, ovato-lanceolata, in acumen mucroniforme producta ; superior brevior, linearis, apice bidentata. 
Stamina tria, antheris luteis. Stigmata purpurea. Glumes scabrae, cum setis suis pallidse. Folia rigidula, 
densa, glauca, margine basin versus calloso-denticulata ciliataque. — Species duae alias sic distinguendae : — P. 
hordeiformis ; spiculis fructiferis florentibus erectis subsessilibus, valvulis flosculi aequalibus—P. patula ; 
spiculis fructiferis patentissimis pedicellatis, valvulis flosculi inaequalibus. 
[With P. hordeiformis we are unacquainted. Between P. latifolia (for we are still inclined to retain 
that name instead of patula) and P. longifiora, 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. longifiora, they are flat or involute towards the apex, decidedly glaucous, 
and the margin toothed only near the base. In P. latifolia the sheaths are strongly striated ; in P. longi- 
fiora, 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. longifiora they are crowded for about one-fourth from the root ; but as in 
both the two upper leaves are 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 Sporoholus 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.
