Type Information

Type Name
C. serotina (L.) Keng (Festuca serotina L.)


The genus name Cleistogenes coincides with “cleistogenes”, the English plural of a technical term in use at the time of publication. Keng’s name is validly published because the technical term is not Latin. Kengia Packer, published as a replacement name for Cleistogenes, is superfluous and illegitimate (see Shenzhen Code Art. 20 Ex. 5)


Replaced synonym of
Kengia Packer, Bot. Not. 113: 291 (1960), nom. illeg.
