CLASS m. ORDEE II.] ARUNDO. 147 



from one to two feet high. Leaves short, broad, tapering at the point, 

 striated, rough, especially on the upper side. Sheaths striated, inflated 

 in the upper part, roughish. Ligula large, lanceolate. Inflorescence 

 a dense, ovate, spike-like panicle. Spikelets small, one or two-flowered, 

 the bractea larger and more elegant than the last species, each valve 

 •with a long tapering point, more or less awned. Glumes equal, longer 

 than the florets, lanceolate, with a long narrow point, membranous, the 

 point roughish, as well as the keel. Glumelles equal, lanceolate : the 

 outer obscurely ribbed, roughish towards the point, and terminating in 

 a long, rough, slender awn ; the inner membranous, bifid at the apex, 

 with two lateral roughish ribs, terminating in a short point. Stigmas 

 feathery. Anther rather large and pendulous. 



Habitat. — Sandy ground towards the sea in the South of England, 

 as near Hastings, Kent, — and Sussex ; but principally in Jersey. 



Annual ; flowering in July. 



The inflorescence of this genus is very remarkable in its structure : 

 the bractea subtending each spikelet are composed of valves similar in 

 arrangement to the perfect floret, and are supposed, with apparent jus- 

 tice, to be florets in an abortive state. 



GENUS :^LIV. ARUN'DO. Linn. Reed. 



Gen. Char. Panicle loose. Spikelets many-flowered : the lower 

 floret bearing stamens only, and naked; the upper perfect, and 

 surrounded by a tuft of hairs. Glumes two, unequal, shorter than 

 the florets. Glumelles two, unequal. — Name, Arundo, the Latin 

 word for Reed, which is supposed to be derived from ardeoy be- 

 cause the plants soon become dry.

 one surrounded with a tuft of pale, shining hairs; the branches long, 

 angular, smooth, slender, and much subdivided. Spikelets linear.
