8. C. purum (Nees ab Esenb. Plantarum in li. med. Boimens. 



Icon. p. 1. t. 1. L. no. 5.); foliis lineari-lanceolatis, 

 periantbio patente obsolete punctato, labello ventricoso 



apice incurvo concolore ciliato integerrimo. Brazil. 



Much like the two last, from which its very narrow 



leaves seem to distinguish it. Flowers green, and 

 scarcely spotted, about as large as those of C. Hookeri. 



9. C. Hookeri (Lindl. Coll. Bot. t. 40. Gen. & Sp. no. 3.) ; 



foliis lanceolatis triplicatis, perianthiis globosis, labello 



apice incurvo : lateribus denticulatis. Brazil. 



Flowers small, yellowish brown. Petals green. Lip 

 green, yellow at the point, spotted with purple inside. 



10. C. globiflorum (Hooker in Bot. Mag. t. 3942.) spica 

 elongata multiflora, periantbio globoso, sepalis petalisque 

 subconformibus ovatis acutis concavis arctissime imbri- 

 catis, labello hemisphserico-globoso, ore contracto oblongo 

 inferne dilatato basi columnse longitudine denticulate, 



columnse brevis setis rectiusculis. Brazil. Much 



like C. Hookeri, and perhaps a variety of it. The sepals 

 and petals are olive-brown, and closely applied to a 

 glaucous globular labellum, the greater part of which is 

 uncovered. 



11. C. longifolium (Lindl. in Bot. Reg. 1839. misc. 154. 



Sertum Orchid, t. 31.) ; foliis longissimis gramineis, 

 racemo cylindraceo pendulo multifloro, sepalis ovatis 

 subrotundis petalorum conformium dorso applicitis, la- 

 bello urceolari a tergo incurvo limbo truncato apiculato 



intus cereaceo glabro margine fimbriato. Demerara. 



Leaves very long and narrow. Flowers bright 



orange, a little bordered with violet, in a drooping ra- 

 ceme, over which they are closely packed for the length 

 of a foot or more ; they are extremely beautiful, and the 

 species is beyond comparison the handsomest of its 

 genus. 



12. C. discolor {^Monachanthus discolor Lindl. in Bot. Reg. 



t. 1735. M. Bushnani Hooker, Bot. Mag. t. 3832. 

 M. roseo-alhus Hooker, 1. c. t. 3736.) ; racemo laxo mul- 

 tifloro, labello hemispherico marginibus planis medio fim- 



briatis. Brazil. Leaves rather narrow. Flowers 



in a loose erect raceme, dull pale purple, with the inside 

 of the lip yellow. They vary in colour to yellowish 

 green, or French- white j and sometimes the lip, which
