Cynodontium strumiferum De. Not. Epil. 280 (i86g). 



Autoicous ; in cushioned yellow-green tufts. Stem i — 2 in. high, 



simple below, with ferruginous tomentum, subdichotomous and fastigiate 



above. Leaves from a broad sheathing base, lanceolate-subulate, 



flexuose and slightly twisting, strongly keeled, nerve vanishing at apex, 



margin revolute below, plane above, entire or crenulate at apex, surface 



in upper part covered with obtuse papillae, as is also the back but finer ; 



areolation as in One. polycarpus but smaller and denser. Perich. bracts 



sheathing, gradually subulate, seta reddish yellow ; caps, gibbous-oblong, 



erecto-cernuous, with the base somewhat constricted and strumose, 



striate and yellow-green at first, finally sulcate and pale brown ; annulus 



compound, lid red with a paler curved beak ; teeth of per. red, adhering

Although so generally united to 0. polycarpus, this appears to be a good 

 species, distinguished by the constant presence of a struma, and the leaves at 

 their upper part papillose on both sides.
