AN INDEX TO ORCHIDS. 



N the subjoined lists of Orcliids^ tlie plants liavo been arranged according to tlie degree 

 o£ heat necessary to bring tliem to perfection — tbus^ tbe '^ stove" species require to 

 be grown in the East Indian house^ those classified as " intermediate '^ thrive in the 

 Brazilian honse, while the ^^ cool-house ^' species are best suited by the low temperature 

 of the Peruvian house. The few ''^ hardy" species here enumerated are almost all natives 

 of Britain or of North America^ and^ being all terrestrial^ are well adapted for culture in 



^ 



outside borders. 



The habit of each plant is stated immediately after the name^ the epiphytal species 

 being marked e^li^ and the terrestrial ones ter; while s-ter indicates subjects of a sub- 

 terrestrial habit of growth. 



The colours are generally arranged according to their importance, the prevailing hue 

 being stated first in each instance. In many species^ however^ the markings are often 

 very variable, so that the colours here mentioned may perhaps be found to differ slightly 

 from those actually seen in a particular specimen. In such cases the markings most 

 frequently found have been given. 



The species of Anoectochihts and Physiirus stand in strong contrast to the other 

 members of the Order^ being grown only for their handsome foliage, and not for the 

 beauty of their flowers, which are small and unattractive. The descriptive colours in 

 these cases, therefore, apply only to the foliage, as indicated by the abbreviation folj 

 preceding the colours.
