The Calypso bulbosa (Calypso orchid), also known as the fairy slipper or Venus’s slipper is the only species currently classified in the genus Calypso. This species is widely distributed and can be found around the undisturbed northern and montane forest of America to Japan.

Calypso bulbosa are small plants of approximately around 10 -14 cm tall. The colour forms are variable which range from pink to red sometimes with darker purple spottings, and yellow beard.

Myco-heterotrophic Orchids relationship with Fungi unveiled

Posted in News around the globe, News from Thailand with tags , , , , on August 24, 2009 by orchideae

In the past a lot of, non-photosynthetic orchids were mistakenly thought to get food by breaking down organic matter in a manner similar to saprotrophic fungi. These orchids were then known to be saprophytes. It is now known that no non-photosynthetic orchids are capable of breaking down organic matters on their own and in order to get the nutrients, example like the orchids featured in this article engage in parasitism, through myco-heterotrophy. Myco-heterotrophic orchids gets all or part of its food from parasitism upon fungi rather than from photosynthesis.

ScienceDaily (Aug. 22, 2009) reported that three Thai orchids ( Aphyllorchis montana, Aphyllorchis caudata Cephalanthera exigua have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon.

The flowers use both odor and colour as attractants, and provide labellum as food reward for the pollinators. The mice pollinate the flowers during their endeavour to eat the labellums.
