Chau. Gen. Gluma subsequivalvis, locustam trifloram aequans. Perianthia bivalvia, 
later alia mascula, triandra ; terminate hermaphroditum, diandrum. 
Obs. Relationem veram Anthoxanthi ad Hierochloem, in prodr. flor. nov. holl. p. 209, pri- 
mum indicatam, optime confirmat planta Javanica intermedise structure a D. Horsfield detecta; 
in hac enim perianthium lateralium inferius masculum bivalve, -superius univalve, neutrum : 
terminate hermaphroditum. II uj us novi generis (Ataxia) habitus potius est Anthoxanthi, 
quocum etiam gluma inaequivalvi quadrat. 
Cum Hierochloe characteribus nonnullis convenit Artlirochloa nob. (IIolcus Palis. Trinity 
et Wahlenb. non Linncei gen. et sp. pi. ed. prima, nec Schreberi nec Gartneri ;) quae tamen 
facile distinguitur ab hoc genere uti et ab Aira et Arhenathero, gluma cum apice pedicelli 
articulata et una cum locusta decidua.
