In the original description of the genus Miscanthus four of the five 
species are true members of the genus, as generally interpreted. The first 
species given by Andersson happens to be a representative of the genus 
Erianthus, for which reason Coville would refer the genus Miscanthus to 
Erianthus as a synonym, and has proposed the new generic name Xipha- 
grostis for Miscanthus of authors, not of Andersson. If an arbitrary rule 
be adopted by which the first species cited must be adopted as the generic 
type, then Coville is correct, but I prefer to interpret the genus by the 
majority of the species, which in this case is clearly four to one. I have 
accordingly retained Miscanthus in the sense that Andersson manifestly 
intended it.
