The names
Aira chinensis Retzius (1783) and
Eriachne chinensis Hance (1861) are based on different types. Although
A. chinensis is the earliest legitimate name for the species, its specific epithet cannot be transferred to
Eriachne without creating a later homonym, which would be illegitimate.
Eriachne pallescens is therefore the correct name for the species.
This is a good forage grass.
