22 The nomenclature of this genus is much confused. Heleochloa Host (Icon. Gram. 1801) appears first 

 without generic description, hence is not effectively published. Beauvois (Ess. Agrost. 23. pi. 7. f. 2.1812) 

 describes Heleochloa but bases it on two species, H. juncea (Ayrostis juncea) and H. phalaroides {Phleum 

 Vhleoides), these not included in Heleochloa by Host. Hence Heleochloa Host, as used by Beauvois, is not 

 the same genus as that of Host himself (loc. cit. and Gram. Austr. 1827). I have, nevertheless, retained 

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