work. Its structure is, however, so remarkable, that we 

 trust the present account of it will not be wholly unin- 



teresting. 



According to Messrs. Loddiges, its native country is sup- 

 posed to be China ; but it is more probably Brazil ; for not 

 only are its affinities altogether American, but two other 

 Brazilian species are now known. 



From all the genera of the tribe to which it belongs 

 it is distinguished by its stigma occupying the apex, and 

 not the face of the column, while its anther is situated at 

 the back. In this last respect it agrees with Notylia, 

 which is, however, otherwise very different. 



It grows tolerably well in vegetable mould, if placed 

 where the air is humid, and the drainage complete. In 

 such situations it flowers in August. 



The two other species above alluded to are the Gongora 

 viridi-purpurea of the Botanical Magazine, and an unde- 

 scribed plant from the Corcovado, of which we find a 

 drawing, and some dried flowers, among a multitude of 

 other interesting Orchideous plants, which, with the libe- 

 rality that marks the man of true science, have been placed 

 in our hands by Dr. Hooker. These two species may be 

 thus named and defined : 



C. viridi-purpurea ; foliis oblongo-lauceolatis, petalis linearibus arcuatis, 



labelli lobo medio acuminato lateralibus sequali. 

 Gongora viridi-purpurea. Hooker in hot. mag. t. 2978. 



Hab. supra arbores in sylvis ad sinum Botofogo in Brazilia. 



The beautiful green colour of the outside of the sepals 

 and petals, together with their rich spotted orange-yellow 

 inside, distinguishes this at once from both the other 

 species. 



C.fusco-lutea; foliis lanceolatis acuminatis, petalis lineari-lanceolatis, labelli 



lobo medio ovato, lateralibus obtusis. 



Hab. supra arbores Brazilia ad Corcovado (exam. s. sp. et v. ic. pict. in 

 herb. Hooker.) 



This verv much resembles C. Loddio-esii ; but the 

 flowers are twice as large, the sepals are dusky brown, 

 with a few reddish lines, and the petals greenish yellow ; 

 while all the parts are destitute of spots except the middle 

 lobe of the labellum.
