22 The nomenclature of this genus is much confused. Heleochloa Host (Icon. Gram. l" 

 without generic description, hence is not effectively published. Beauyois (Ess. Agrost. 23 

 describes Heleochloa but bases it on two species, H. juncea (Agrostis juncea) and H. phaH 

 phleoides), these not included in Heleochloa by Host. Hence Heleochloa Host, as used by 1 

 the same genus as that of Host himself (loc. cit. and Gram. Austr. 1827). I have, never" 

 Heleochloa as generally understood, that is, as figured, though not described, by Host.
