SA Orchids:Genera

[Terrestial-summer rain] [Terrestial- winter rain] [Terrestial-widespread] [Epiphytic] [Epilithic]

There are 54 orchid genera in our southern African region. On this page we have divided them into terrestrial orchids (grow in the ground), epiphytic orchids (grow on trees) and epilithic orchids ( grow on rocks). Terrestrial orchids are further divided according to the rainfall region where they occur (summer-rainfall region, winter-rainfall region, both regions). In important genera we provide links to a more detailed and well-illustrated description.

Gastrodia, small genus of yellow-brown, leafless orchids from tropical Asia and Australia; our single species was accidentally introduced and is found on Table Mountain, Cape Town.

Pachites, small genus of two rare species, endemic to the Western Cape; one of the very few exceptions of orchids with a regular perianth; flowering only after fire.
