The flowers of this are very much smaller than even these of H. crucigera , and 

 white with a very little green. It is from Guatemala and is the no. 389. Lodd.

Of the Genus of this plant I am extremely doubtful. It was received in a living 

 state, but the anther had falien away, and no pollenmasses were to be found.

Perianthium clausum. Sepala et petala subaequalia, angusta; illorum 

 lateralibus invicem discretis sed basi columnae adnatis. Labellum 

 posticum, cum columna connatum , refractum , inappendiculatum, inte- 

 gerrimum, sepalis subconnatis. Columna erecta, basi nullo modo pro- 

 ducta, apice biaurita. Anthera dorso co§vexa, carnosa 4-IocuIaris, val- 

 vulis membranaceis longitudinaliter dehiscentibus. PoIIinia 4, collate- 

 ralia (00 00), materie parca granulosa stigmati annexa. Herba epiphyta 

 caulibus teretibus ascendentibus , articulatis. Folia linearia, coriacea, 

 apice emarginata. Racemi terminales, pauciflori, bracteis vaginis mem- 

 branaceis ex squamis cartilagineis imbricatis erumpentes. 



This genus is in some respects related to Isochilus and Dinema , from which how- 

 ever it difl^ers entirely in the slructure of its pollenmasses. Ils nearest afflnity is 

 certainiy with Coelogyne and particularly with the section Panisea, from which it is 

 chiefly disiinguished by its posterior labellum connate wilh the coiumn, like that of 

 an Epidendrum. 1 am unceriain if ihis genus is not the same as Elleanthus of Presl.
