Sievekingia is a genus of the subtribe Oncidiese, estab- 

 lished by Reichenbach f. (" Beitr. Syst. Pflanzenk.," p. 3) 

 for a Costa Rican Orchid, 8. suavis, Rchb. f . To this three 

 species have since been added, namely, 8. fimbriata, Rchb. f . 

 (" Flora, 1886," p. 449), also from Costa Rica, 8. Jenmani, 

 Rchb. f. (1. c. 450) from British Guiana, and the subject 

 of the figure here given. 



8. Eeichenbachiana was discovered in 1879 by Mr. F. C. 

 Lehman on the Andes of Ecuador, at an elevation of 2000 

 to 3500 ft., when only a single specimen was met with. 

 In 1890 its discoverer undertook to search for more, but 

 found only five, on his estate at Cauca. Of these one came 

 into the possession of Sir Trevor Lawrence, who obligingly 

 sent the drawing here reproduced.
