diametei-, the lower clothed for about I the length with the leaf- 

 sheath or its remains ; leaf-blades flat, G to 7 lines long by a 

 little over 2 lines broad, more or less spreading. Panicle i to 

 2" in. long, spikelets barely 1 line. Glume I. 'i line, gl. II. i line, 

 gl. III. |- line Avith a pale about ^ its length, fertile gl. 'i line. 



Is near the tropical South American P. parvifolium Lam., but 

 distinguished by its ovate leaves and smaller dense panicle. It 

 recalls P. pusillum Hook. f. (Cameroons) in habit, but is a largei-, 

 stronger plant. P. jmsillum, moreover, has acute sparsely hairy 

 spikelets.

 specimens only 6 to 9 in.). Veins of leaf prominent on the back, 

 sheaths striate with well-marked midrib, sometimes almost 

 keeled ; blade generally 3 to 6 in. long, by 1 line or less in 

 width, sometimes longer in the subulate-filiform leaves. Panicle 

 overtopping the leaves, 3 to 6 in. long, primary branches generally 

 spreading at about 45° ; spikelets ^ to 4 line long, greenish ; 

 gl. IV. enclosing a similar but slightly smaller pale and ^ flower.
