 Echinochlaena, under which this species was originally described, and 

 to which it has been referred back again by Hitclicock and A. Chase 

 (see below), is an exclusively American genus which differs from Pseud- 

 echinolaena in many respects, as in its densely packed spikes, the many- 

 nerved lower glume, the ,,eglandular" always unanned upper glume, the 

 uniformly papery 5-nerved lower valve which is accompanied by a sharply 

 2-keeled flat valvule, the basally appendaged fertile valve and the acutely 

 auricled or toothed flaps of its valvule, and finally the flatter grain 

 which is marked with a panduriform line on the face extending through 

 its füll length and possesses a sl ender linear hilum.
