all syn.) and even to G. hordeiformis, N. ab E. (or G. caudata, Kunth,) than to any species of Penicillaria: 
nd this appearance is supported by the structure of the spikelets, which is truly that of Gymnothrix. In 
Penicillaria, however, the inflorescence is a raceme with the pedicels and involucres persistent ; in Gymno- 
thrix it is usually a spike, the sessile involucres being deciduous : in the present plant, it is a raceme, but 
the short pedicels, as well as the involucres, are deciduous, thus agreeing in every point with the genus to 
which we have removed it. The leaves are glabrous, but, at the same time, scabrous on their margin. The 
spike, or rather raceme, is usually about three or four inches long ; we have rarely seen it so long as des- 
cribed above : at first it is acute at both ends, but afterwards the pedicels often spread out horizontally, pre- 
senting a lax appearance. Pedicels frequently a line and a half long, articulated with the rachis. The 
bristles of the involucre are at first pale, but afterwards of a beautiful purple from almost their base to the 
apex. From G. alopecurus, the only other species with distinct pedicels, it is readily distinguished by 
their being almost as long as the spikelets. Trinius’ figure is excellent, if taken from a young specimen ; 
he, and Nees von Esenbeck, and we also, have found only one spikelet in each involucre : Kunth says that 
there are one or two.]
