This is probably one of the more commonly offered Oeceoclades species in the orchid market. I got my from Burleigh Park Orchids an Austrialian nursery by sharing a shipment with other local orchid hobbyists. Once again, the label says it is O. decaryana. Many other offers and photos on the web suggest it is O. calcarata. This is my first and oldest pot of Oeceoclades. And one of the most prolific growers with multiple growing points. Even the bud on top of a old pseudobulb is capable of giving rise to an new offset - bottom right. It is extremely succulent and drought tolerant with very strong thick roots covered with exceptionally spongy velamen. Unfortunately, it is flower shy; a firm identification will have to wait. Garay & Taylor* mentions that the type specimen is without precise locality, probably again from deciduous forest of northern or western Madagascar.
This post and the last few posts cover my Oeceoclades collection. If someone is going to order an Oeceoclades petiolata from ISI 2008 offering contact me!
