LINDLEY ON THE GENUS EPIDENDRUM. 81 



VII. — Notes upon the genus Epidendrum, by Professor 



LlNDLEY. 



Having lately had occasion to reconsider the large genus 

 Epidendrum, I have been led to attempt its subdivision upon 

 more natural characters than those employed in the Genera 

 and Species of Orchidaceous plants, the result of which is given 

 in the following account of the subgenera I propose to adopt. 

 In limiting them I have had recourse to the organs of vegeta- 

 tion as well as fructification, and I am persuaded that in the 

 whole Orchidaceous order the same means will be necessary 

 in any large genus, for there seems to be a universal tendency 

 to produce a variety of modifications of the stem and leaves 

 under the same organic type.
