(By Hannah J. Haynie): "A noun class/gender system categorizes nouns for the purposes of grammatical agreement with other constituents in the noun phrase or other inflectional morphology. See the classification wiki page for more information on our definition of noun class/gender. Noun class/gender assignment may be based on one or several factors. This feature focuses on whether one of these factors distinguishes plants from other concepts. For this feature to be coded 1, there must be a clear pattern in which nouns that refer to plants or some subset of plant referents are assigned to one or more specific noun classes. ❡
Although the semantic factors in noun class/gender assignment are not always perfectly clear-cut, this feature targets those systems in which certain nouns are assigned to a particular class because their referents are plants. Systems in which several nominals with plant referents are assigned to a particular class because of their phonology or due to some more or less arbitrary assignment are not the target of this feature. That is, plant status must be a relevant factor in the assignment of gender. However, it does not need to be an absolute deciding factor or the only relevant factor in gender/class assignment for a particular category."
