Although only now brought into notice, lite aperies was mmiy year* *ine* discovered by 

 Or- A on Martin*, who found if n^itr Tnrnma nn the kink* of tin- Itio Xegro, in woods at (he Bnrra 

 tie Rio Negro, ami in forests m nr Pari. 



h i* readily distinguished from nil previously de*eribed specie* by its thnvlohcd lip with acute 

 lateral Moments, the middle lobe being Hut, toothtcUrd and emarginate, and by the cluster of 

 elevated veins at the junction of tho eptchilium and bypoelrilium, 



Tlie species of this beautiful genua have not been well defined, They are with dilliculty pre- 

 served as dried ipcCfctena ; they have been described at various times from plants in different states, 

 and for a small genu* there is probably ax much to comet or amend in the genus Cattleya as in any 

 in the whole order. I therefore lake thU opportunity of making some observalions upon this 

 subject 



In the first place it i* necessary to remove from the genu* Cattleya coccinca. which is Sophro* 

 mti* grandilloru; C. Grahami and maxima, which are Lrclias ; and C. domingensis. which is 

 possibly a species of Barkcriu. 



Of the genuine specie* then left there are two sections, the fii>! <if which bos mi undivided lip ; 

 and the other a lip with three deep distinct Iota*. 



The/™* tecii&n consist* of C. crispa. labi.ua. bicolor, pumila, and Mossiii*, with the unpublished 

 C. Skinneri of Mr, Hntcinaii, which is nearly related to the last. 



Of the second stcftmt C. elatior has to be expunged, having been founded upon a had toll 

 specimen of C. guttata ; C, Perrinii is readily known by the narrow middle Iota of it* lip, and its 

 cuniculaie ovary; C. eilrina has yellow flower*, and is otherwise well marked; C. supcrta has 

 already been spoken of; the remainder consist of C. Forbesii, intermedia, Loddigcsii, ovata, 

 Ilarrisonii, and maritime Of these C. Forbcaii has the back sepal and the petals very narrow, the 

 middle lobe of the lip rounded and not entarginale. and two elevated lines along the middle of tlie 

 axis; C- maritima has small roundish ovate leaves, but its llowcrs have not been sufficiently 

 examined; and C. intermedia, ovata, and Harrisonii are probably varieties of C, Loddigcsii ; at 

 least I am unable to point out any positive marks of distinction between them.
