CALYPSO. 



Salisbury bestowed the above name upon this monotypic 

 genus after that of the Greek goddess, the species being an 

 elegant terrestrial Orchid of the tribe Epidendrece. It thrives 

 well in half-shady spots on the margins of rock-gardens 

 or as a bog-plant, in a soil composed of peat, leaf-mould, 

 and sand. It should be thickly covered with cocoa-nut 

 fibre refuse during winter. 



C. borealis {Salisb.). — Flowers solitary, delicate rose and brown, 

 with yellow crest on the lip ; labellum longer than the sepals, the 

 lateral lobes cohering in their upper parts over the saccate 

 central one, which is usually bifid at the lip, resembling those of 

 Cypripedium. Leaves solitary, thin, many-nerved, ovate or 

 cordate. Stems usually thickening into pseudo-bulbs. Northern 

 Hemisphere, 1820. (B. M., t. 2763.) 



CAMARIDIUM. 



About a dozen species of stove, epiphytal Orchids, 

 natives of tropical America, are included in the genus 

 Camaridiuni (^Lindl.), of the tribe Vaiidece. The name is 

 derived from kainara, meaning an arched roof, and is in 

 allusion to the arched tip of the stigma. Flowers 

 mediocre, solitary, produced from the axils of the dis- 

 tichous leaves. The species require an intermediate-house 

 temperature.
