can be a Maxillaria ; namely, a labellum attached to the 

 column by a moveable joint, or, as we technically say, articu- 

 lated with the column. This is found in every true Maxil- 

 laria, and therefore I have no hesitation in separating from 

 it a Demerara plant which flowered lately with Mr. Barker 

 at Birmingham, in which this character is wanting. It 

 may be called Stenia in allusion to the singular narrowness 

 of the pollen masses. 



Stenia. 



Perianthium explanatum, subaquale, sepalis lateralibus basi obliquis. 

 Labellum cum basi columnae continuum, (indivisum), concavum, disco appendi- 

 culatum. Columna semiteres, basi producta, apice rotundata, mutica. Anthera 

 bilocularis. Pollinia 4, linearia, geminata, basi sejuncta, dorsalia minima. 



Caudicula subquadrata acuta (pubescens). Herba acaulis, ebulbis. Folia 



oblouga, basi angustata, apice recurva. Flores solitarii, radicales, basi ovarii 

 bracteolati.

There is moreover an unpublished genus, called Huntleya 

 by Mr. Bateman, in compliment to the Rev. J. T. Huntley, 

 an ardent cultivator of Orchidaceous plants Tsee fol. 1721 of 

 this work), of which the original species was found, accord- 

 ing to a memorandum I have received from Mr. Bateman, 

 in Demei-ara by Mr. Schomburgk, and of which another 

 and very fine species occurs among Mons. Descourtilz's 

 Brazilian drawings. These plants manifestly difi'er from 

 Maxillaria in combining with the distichous habit of a 

 Vanda, a flat, spreading labellum, which is unguiculaie with 

 the free base of the column, and furnished with a fine fringed 

 appendage at its base, and a column broadly winged towards 

 the apex. This genus may be established upon the following 

 character, which I take from the species of M. Descourtilz. 



Huntleya. 



Perianthium explanatum, subsequale, sepalis lateralibus basi antice involutis 

 vix obliquis. Labellum planum, unguiculatum, rhomboideum, patens, basi 

 longe fimbriatiim, cum basi libera producta columnte articulatum. Columna 

 clavata, apice cucullata, margine alata. Anthera bilocularis mutica. Pollinia 4. 

 Herbae caulescentes. Folia ligulata, disticha. Flores axillares (solitarii).
