12. P. psammophilum Welw. ms. in herb ampliatum. 
Plants covered with a tawny pubescence, 6 to 18 in. high, 
varying greatly in habit according to the development of inter- 
nodes, size of leaves, and density of inflorescence; shoots often 
densely leaved ; leaf-sheaths loose, generally short and broad ; 
ligule represented by a ridge of short hairs; blades narrowly 
lanceolate tapering to an acute or acuminate apex; spikelets 
shortly stalked, crowded in short oblong or linear dense panicles, 
arranged closely or laxly on the main rhachis, ovate, 2 lines long ; 
glume I, thin, ovate, acute, 3 length of the spikelet, gls. II. and 
III. membranous, subequal, broadly oval and ovate, the latter 
subtending a pale and ¢ flower ; fertile gl. 3 the length of the 
second and third, oval, subacute. 
Specimens all apparently annual. Some (No. 2625) forming 
small plants 6 in. high with short spreading decumbent closely- 
leaved shoots ending in a dense panicle linear-oblong or lanceolate 
in outline. Others (No. 2624) have elongated widely branching 
spreading shoots, geniculate at the base, 1} ft. long, with inter- 
nodes 2 to 23 in. long, 1} line thick below and bare above the 
middle, and a lax inflorescence 6 in. long. Others (No. 2626), 
which Welwitsch considered a distinct species, have a very thick 
stem (3 lines in diameter at the base), densely clothed with large 
woolly ascending leaves. Internodes rigid, lower nodes often 
swollen. Leaf-sheaths generally loose, very broad and compressed, 
1 to 21 in. long by 2 to 3 lines broad or narrower near the 
inflorescence, in the thick-stemmed plants 13 to 23 in. long by 
7 to 5 lines broad, and with conspicuous parallel veins. Leaf- 
blades linear-lanceolate or narrowly lanceolate from a truncate
