[Our specimen, also collected by the Rev. Mr. Vachell, and under the same number from Professor Henslow,
does ^ o t quite agree with the above deseription ; we, therefore, insert also the specific character m’o had
drawn up previously to receiving that by Prof. Nees von Esenbeck Culmo (apicem versus saltern) aphyllo
glaberrimo lævi tereti-compresso apice uniangulato, rachi leniter flexuosa, spiculis oblongis in spicis densis
dispositis, spicis erectis inferioribus compositis ovato-oblongis breviter pedunculatis mediis subsessilibus,
ovatis superioribus simplicibus confertim glomeratis, bracteis pruniosis omnibus spica propria multo brevioribus,
squamis oblongo-lanceolatis, exterioribus obtusiusculis sterilibus, interioribus carinatis acuminatis.—Thus
the principal difference consists in the lower partial spikelets of our plant being peduncled, and forming a
kind of panicle.]

[To the description and character given by Prof. Nees Von Esenbeck, we may add that the caryopsis is at
first only slightly rugulose, the elevated parts being covered with numerous short bristles : afterwards it is
almost or quite glabrous; the lobes of the hypogynixm are obtuse and not more than one-fourth the length
of the caryopsis. Tho margins of the leaves and sheaths are often only slightly scabrous.]
