Vanda Orchids
Sunday, January 27th, 2008The genus Vanda belongs to the large group of monopodials which are widely distributed throughout Africa and the Indian subcontinent, the Far East and Northern Australia. The plants grow by producing a single upright rhizome with leaves on alternate sides. New leaves always come from the top.
Aeridovanda Mundyii shows the complete adaption of an epiphyte. It can exist with nothing around the roots. It is monopodial and has little reserves of water. The continued existence of the plant is completely reliant upon the foliage, terete leaves which have become completely rounded, thinner than a pencil, their surface reduced to the minimum to prevent overheating and dehydration.
In cultivation it is ideally suited to culture on bark. Occasionally losing a few leaves, which arc not missed, it is an evergreen which can be regularly sprayed throughout the year, and not given the completely dry resting period of the Asian species.
The thin, diminutive pseudobulbs carry little food reserves and would not sustain the plant through any lengthy period of drought, although in extreme seasons the soft leaves would quickly be shed to help the plant.
