WORK ON ORCHIDS 



175 



Cattley, an early patron of Lindley, was one of the most suc- 

 cessful of the early cultivators of epiphytic orchids. 



The chief of Lindley's published contributions to the know- 

 ledge of orchids, apart from scattered figures and descriptions 

 in the Botanical Register, the Garde?iers' Chronicle, Lindley and 

 Paxton's Flower Garden, the Journal of the Linnean Society, 

 and in other serials and periodicals, are to be found in The 

 Genera and Species of Orchidaceous Plants, 1830 1840, in which 

 are described all the species (1980) known of 299 genera; Sertum 

 Orchidaceum (1838); Folia Orchidacea, 1852 1855; and The 

 Vegetable Kingdom. 



It is unfortunate that no attempt has as yet been made to 

 catalogue the species described by Lindley ; but with regard to 

 genera an approximate list of those proposed by him may be 

 attempted, and is interesting as giving some idea of the extent 

 and value of Lindley's investigations in the group. 



In the third edition of The Vegetable Kingdom he estimates 

 the number of orchid genera at 469. Bentham and Hooker 

 (^Genera Plantarum, 1883) admit 334, and new genera proposed 

 since that date amount to 125. Pfitzer (Engler and Prantl, 

 NatiirlicJien Pflayizen-familien, 1889) describes 410. 



The following is a list of Lindley's genera, admitted by 

 Bentham and Hooker, in the sequence in which they appear 

 in the Genera Plantarum :
