12. P. psammophilum Welw. ms. in herb ampliatum. 



Plants covered with a tawny pubescence, G to 18 in. high, 

 varying greatly in habit according to the development of intev- 

 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 shoit oblong or linear dense panicles,^ 

 arranged closely or laxly on the main rhachis, ovate, 2 lines long ; 

 glume I. thin, ovate, acute, | length of the spikelet, gls. II. and 

 III. membranous, subequal, broadly oval and ovate, the latter 

 subtending a pale and ^ flower ; fertile gl. ^ 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. Othei-s (No. 2624) hnve elongated widely branching 

 .spreading shoots, geniculate at the base, 1-^- ft. long, with inter- 

 nodes 2 to 2^ 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 2^ in. long by 2 to 3 lines broad or narrower near the 

 inflorescence, in the thick-stemmed plants l-^^ to 2^ in. long by 

 7 to 5 lines bi-oad, and with conspicuous parallel veins. Leiif- 

 blades linear-lanceolate or narrowly lanceolate from a truncate
