MR. G, BENTHAM ON GRAMINEX. Gi 
P. aurea, Benth. (the original genus Zulalia, Kunth), P. articu- 
lata, Trin. (Pogonatherum contortum, Brongn.), P. eriopoda, Hance 
(Spodiopogon angustifolius, Trin.), P. longisetus (Erianthus lon- 
gisetus, Anders.), P. versicolor (Erianthus versicolor, Nees), P. fili- 
Jolius (Erianthus filifolius, Nees), and a few others. 2. Lepta- 
therum, with slender spike-like branches, of which the hairs are 
few or short, so as to appear sometimes quite glabrous; this 
section includes P. glabrata, Trin. (Eulalia glabrata, Brongn.), 
P. nuda, Trin. (P. imberbis, Nees), P. Willdenowianum (the genus 
Microstegium, Nees, P. lancea, Nees, published also by Nees as 
his genus Leptatherwm, and probably also Steudel's Nemastachys). 
Sprengel's Pollinia would have had the right of priority over 
Trinius's; but that proved a farrago made up of a few heteroge- 
nous species of Andropogon, Chrysopogon, and Pollinia. 
7. PodGoNATHERUM, Beauv. (Homoplitis, Trin.), is a single tro- 
pical and subtropical Asiatic species, very well marked by its 
slender, much branched habit, the single spikes, and the slender 
awns arising as well from the second empty glume as from the 
flowering one. 
The Arthraxee, or second group of Andropogone&, consist of 
three genera, which have the inflorescence of Pollinia; but the 
second spikelet of each pair is generally reduced to a bare stipes, 
or is even quite deficient, bringing a few species very near to the 
Zoysiew, differing chiefly in their subdigitate spikes, whilst a few 
others, in which the spikes are single, have the rudiment of the 
second spikelet of true Andropogonex. 
8. Apocorrs, Nees (Amblyachyrum, Hochst.), has five or six 
species from East India or the Malayan archipelago, characterized 
by the very broad truncate outer glume enclosing the rest of the 
spikelet. Among the species A. Royleanus, Nees (Ischemum 
paleaceum, Trin., Andropogon paleaceum and A. himalayensis, 
Steud.), is remarkable for the awn often (but not always) reduced 
toa small fine point, or even entirely wanting ; and A. tridentata 
(Andropogon tridentatus, Royle) has, on the contrary, a very long 
awn, and the young spikes are usually enclosed in à large spathe- 
like bract. 
9. Drerta, R. Br. (Haplachne, Presl, Didactylon, Zoll. and 
Mor., Psilostachys, Steud., Pterygostachyum, Nees), about ten 
Species from the Indo-Australian region, has very slender spikes, 
the lower empty glumes very narrow and rather rigid, and usually, 
if not always, only two stamens.
