Bentham (Journ. Linn. Soc. xix. p. 46) in reference to this says :—‘ Berchtoldia 
junciformis, judging from the specimens Fournier quotes, is one of the large coarse 
forms of Panicum (Echinochloa) very nearly allied to, if not varieties of, Panicum crus- 
galli; the other, Berchtoldia oplismenoides, Fourn., is unknown to me, but must, from 
his description, be referable also to Echinochloa.” We have only seen Spruce’s specimen 
of the Oplismenus holciformis, none of the Mexican specimens being in the Kew 
Herbarium.
