1. P. meyerianum, Nees, FI. Afr. Austr. 32. Perennial, to over 
3 ft. high, often apparently tall. Culms erect or ascending from a 
decumbent rooting base, simple or more often sparingly branched, 
stout, terete, glabrous, 5- to many-noded, sheathed all along or some 
of the upper nodes shortly exserted. Leaves more or less glaucous ; 
sheaths tight, firm, glabrous except at the silkily pubescent or villous 
nodes or softly ciliate upwards with a delicately pubescent or villous 
transverse zone at the junction with the blade or loosely and softly 
hairy all along, with the hairs tubercle-based and deciduous ; ligule 
reduced to a fine ciliate rim ; blades linear-lanceolate from a rounded 
contracted base, long-tapering to a fine point, 3-8 in. by 3-7 lin., 
firm, somewhat succulent, glabrous, smooth except along the scaberu- 
lous margins, midrib of large leaves slightly prominent below and 
whitish above towards the base, otherwise very fine or indistinct 
like the lateral nerves. Panicle oblong to ovate-oblong, 3-6 in. long, 
contracted or opened out by the spreading of the lower branches 
and then up to 4 in. wide, divided to the third or sometimes the fourth 
degree, glabrous except the silkily pubescent or villosulous motile 
bases of the primary branches and some long fine hairs on the 
pedicels ; primary axis slender, angular, scaberulous upwards ;
