Botanical orchids

Botanical orchid is a loose term to denote mainly small flowered tropical orchids belonging to several genera (not necessarily related to each other) that don't fit into the "Florist" orchid category. A few of these genera contain enormous numbers of species. Some, such as Pleurothallis and Bulbophyllum, contain approximately 1700 and 2000 species, respectively, and are often extremely vegetatively diverse. The primary use of the term is among orchid hobbyists wishing to describe unusual species they grow, though it is also used to distinguish naturally occurring orchid species from horticulturally created hybrids.
