Panicum Helopus of Bentham’s Flora Australiensis, vii. 476, is partly 
* — — Brachiaria notochthonoj Stapf ( Panicum notochthonum, Domin ; the Darling 
“River plant), and partly Brachiaria ramosa, Stapf (Mueller’s specimen from the 
Lower Victoria River). The plant figured by Duthie as Panicum Helopus in 
Indig. Fodd. Grass, t. 7, is also B. ramosa. Panicum javanicum, Poir., fre- 
quently confused with U. Helopus, is U. panicoides, Beauv., a distinct species 
-f° r which the combination U. javanica will have to be made. The original 
P. Helopus represents the state with pubescent spikelets, and was described 
from specimens collected in Mauritius, where, however, also plants with glabrous 
spikelets have been collected. The pubescent state is predominant in India, 
and all the Rhodesian specimens quoted here except Appleton, 35, belong to it. 
On the other hand Petherick’s, Schimper’s (no. 61) and Paoli’s plants and the 
South African material of U. Helopus at Kew possess perfectly glabrous spikelets. 
Specimens with pubescent spikelets and at the same time an appressed silvery 
fringe to the lower floret were collected by Jacquemont near Poona in India. 
The presence or absence of a hairy vestiture in the spikelets does not appear 
to be correlated with any other characters ; but it has to be observed that the 
spikelets of the specimens from the African mainland, particularly those from 
Rhodesia and South Africa, are on the whole slightly larger and more acute than 
those from Mauritius and India. 
8. U. rudis, Stapf. Annual, in ample erect tufts, over 1 ft. high. 
Culms rather stout, subterete or angular, sheathed almost all along, 
I branched from most nodes except the uppermost, with the branches 
erect, about 6-noded, internodes pubescent or hirsute below the nodes. 
Leaf-sheaths rather tight, pale, finely striate, densely hirsute to 
villous (including the nodes) with long yellowish hairs ; ligules 
reduced to a densely cilia te rim ; blades linear-lanceolate to lanceo- 
late from a broader and semi-amplexicaul or scarcely widened base, 
acute with a callous point, 2-6 (rarely more) in. by 4-6 lin., flat or 
involute upwards, rather stout, but soft, pale or yellowish-green, 
villous with short and long hairs, margins finely cartilaginous and 
crisp, with tubercle-based cilia, midrib very slender, lateral nerves 
obscure. Inflorescence shortly peduncled or those of the lower 
branches more or less enclosed in the supporting leaf-sheaths, of few 
obliquely erect or spreading rigid subsessile racemes ; common axis
