Kamosia Merr. gen. nov. in Philipp. Jourii. Sei. XI (1916) p. 2. 



The genus is rather anomalous in several respects, the plant in 



habit strongly resembling some forms of Panicum nodosum Knuth, 



except in its shorter culms, and eonie forms of Ichnanthus pallens 



Mmiro, but its floral structure removes it at once from the Paniceae.

 Scutachne Hitchc. et Chase gen. nov. in Proceed. Biol. Soc. Washington XXIV 



(1911) p. 148. 



Scutachne differs from other genera of this tribe in having a 



second glume and sterile lemna leathery-indurated and nearly as firm 



as the fruit. Bluffia Eckloniana Nees (which is referable to Alloteropsis) 



and Alloteropsis semialata (R. Br.) Hitchc, especially the first, have 



sterile lemnas subindurated like their fruits but the two glumes are 



gimilar. The subindurated, mucronate fruit, the lemna margine mem- 



branaceous and flat above, the palea free at the summit, further diffe- 



rentiate Scutachne from Panicum.
