With these characters are combined a pair of 2-lobed 

 pollen masses, sessile upon a transverse gland. The genus 

 thus restricted will be found to comprehend two natural 

 groups, one of which consists of plants that, like C. aloi- 

 folium, form neither stem nor pseudo-bulbs, but throw up 

 several leaves from the surface of the soil ; the other of 

 species with a creeping rhizoma, from which at intervals 

 spring pseudo-bulbs, bearing from 1 to 3 half-coriaceous 

 leaves. It is to the latter that the subject of this Plate is 

 referable. Besides these, it will probably not be expe- 

 dient, with our present imperfect knowledge of the struc- 

 ture of those plants, to exclude such species as C. diurnum 

 and utriculatum, both of which are types of additional 

 groups ; and perhaps our Camaridium ochroleucum will 

 be better reduced to Cyrnbidium than retained distinct. 



A very large portion of the Willdenovian species of 

 Cyrnbidium are referable to other genera, especially C. 

 echinocarpum and its allies, which form a genus we call 

 Dichaea. The Maxillaria gracilis of the Botanical Cabinet 

 is either this in a sickly state, or a nearly allied species.
