VII. DIGRAPHIS. DIGRAPHIS. 



A single species, often united with JPhalaris, of which it has the 

 rudimentary glumes immediately under the flowering ones, but it is 

 very different in inflorescence, and the outer glumes are not winged on 

 the keel. 



1. Reed. Digraphis. Digraphis arundinacea, Trin. 

 (Fig. 1151.) 



(Phalaris, Eng. Bot. t. 402.) 



A reed-like perennial, 2 to 3 feet high, with rather broad, long 

 leaves, densely tufted at its base. Spikelets very numerous, in a 

 panicle 6 to 8 inches long, rather compact, but not closely imbricated 

 nor spike-like as in Phalaris and Phleum ; the lower branches often 

 spreading. Outer glumes about 2 lines long, lanceolate and pointed, 

 but not awned, keeled but not winged, pale-green or whitish with 

 green nerves. Flowering glume smooth and shining, and hardened 

 round the seed as in Phalaris, with two minute, linear hairy scales or 

 rudimentary glumes at its base, one on each side.
