O. cornigerum ; pseudo-bulbis oblongis sulcatis monophyllis, foliis ovalibus 

 acutis sessilibus striatis scapo simplici decumbente paucifloro brevioribus, 

 sepalo supremo petalisque obovatis concavis undulatis obtusis inferioribus 

 minoribus angustioribus basi connatis, labelli lobis lateralibus linearibus 

 connatis intermedio obovato subrepando undulato, crista antice verrucosa 

 truncata postice lamella crenata. transversa cornuta, columnar alis lineari- 

 bus obtusis porrectis. 

 Folia 2-3 poll, lonrja, patentissima. Scapus debilis, 5 poll, longus. 



Anthera membranacea, truncata ; clinandrio valdi proclivi. 



A rare little species of Oncidium, native of Brazil, for 

 which we are indebted to the Hon. and Rev. W. Herbert. 

 The drawing has been in our portfolio ever since August 

 1830. We have never met with it in the collections round 

 London, neither has it been received from any of our nume- 

 rous country correspondents. It may, therefore, be sup- 

 posed to be extremely uncommon. 



Perhaps the smallest flowered of all the genus of Onci- 

 dium properly so called. The truncated callosity of the 

 crest, with a sort of 2-horned screen at its back, and the 

 two lateral erect lobes of the lip at its side, is, when viewed 

 in profile, not very unlike a bull's head in miniature.

* So named from oyx,os, a tumour ; the genus being composed wholly of 

 species the labellum of which bears at its base warts, tumours, or other 

 excrescences.
