quadrant : in nostra culmi decemangulares, squamæ vix carinatæ lateribus sanguineis, 
margine hyalina, subtus purpureo-punctulatæ, — caryopsis manifeste trigona angulis 
prominentibus, basi attenuata, apice truncata, — styli bulbus brevis, latus, — 
stamina tria, setæ nullæ. constant. Attamen ad speciem Bôckelerianam, nec ullam, 
referuntur.
