Definition

Noun: 1. A taxonomic category in biological classification: "Genus Odontoglossum" is the scientific name for a specific, large, and significant genus of orchids. This genus belongs to the family Orchidaceae. 2. A group of related orchid species: It comprises numerous tropical American orchid species, most of which grow as epiphytes (on other plants for support, but not as parasites). Many species popular in cultivation were historically classified under this genus.

The reference to species being "often placed in other genera" is a critical part of understanding current usage.
