 Lindl.' Bot. Reg. XXVIL 1841. Misc. 33: 



This plant possesses no beauty , evcn when represented upon paper. Ii is either a 

 bad specimen of Leochiius oncidioidns of Knowles and Westcott, or a species so nearly 

 allied , ihat I am not at presenl able lo point out the diff. between ihem. VVith On- 

 cid. carinalum and another spccies or iwo it forms a group readily known by On- 

 cidium proper, by the large aniher, the two armed column, and some pcculiarities in 

 the lip. If it sbould be eventually separated from Oncidium which seems probable, 

 Ihe name of Leochilus although not very appropriate, must be reiained for it.

Perianthium connivens, sepala lateralia basi connata, petala confor- 



mia, labellum columna continuum integerrimum, columnanana basi alata, 



gynizus subquadratus, clinandrium marginatum , roslratum , pollinia 2 



globosa, cavata, anthera unilocularis. Caudicula linearis. Glandula minuta. 



Very nearly relaled to Oncidium parlicularly .to 0. carinatum from which it princi- 



pally dilTers in having smooih, not a tuberculated or crested labell. It is a nalive of 



Mexico, and is in the colleciion of G. Barker. 



Bot. Reg. XXVHI. 1842. Misc. 22: 



In many respects it is extremoly like Rodriguezia , and iis hobit is not at variance 

 wilh ihat genus , but there are some circumstances that distinguish it, In the flrst 

 place, ihc lip is not parallel with the column , and sccondly the two arms of the co- 

 lumn proceed from below the siigraa and noi from ihe uppcr edge of that organ. In 

 addiiion 10 this ihe anilier is disproportionally large as compared with the column, 

 and ilicre is a honey |)orc near llie base of tlie lip. Froni Oncidium this genus is 

 weil disiinguishcd by the position of the orms of the short colunin , and the honey 

 pore.
