This is a genus, the characters of which have not been 

 before defined. It is only known to botanists as a name that 

 exists in the list of Orchideous genera printed at the end of 

 my Collectanea Botanica, with a reference to the " Epipactis 

 amplo flore luteo vulgo Gavilu" of Feuillee. At the time that 

 work was published, I had only examined one species, from 

 the inspection of which I referred the genus to Neottiese. 

 An analysis of the species now about to be described has 

 shown me that it ought rather to be placed with Arethuseae ; 

 if, indeed, these two sections are really sufficiently distinct. 

 The affinity of Chloraea to Lyperanthus and Caladenia has 

 been already noticed. From these, and all other known 

 genera of the same Natural Order, it is obviously distinguished 

 by the incrassated, often dilated apices of the two lower 

 sepals, and of the labellum. 



1. C. disoides ; sepalis inferioribus porrectis apice emargi- 

 natis attenuatis, labello unguiculato cristato : lobis lateralibus 

 cucullatis membranaceis nudis, intermedio carnoso glanduloso. 



Sponte crescit circa Valparaiso : Februario florentem legit M'Rae, (v. s. sp.) 

 Leaves erect, acute, sheathing, as long as the somewhat leafy scape, 

 which rises to the height of six or eight inches. SquamcB of the 

 scape membranous, inflated, acute. Mower ringent. Sepals mem- 

 branous, veiny, the three upper conniving, erect, lanceolate, somewhat 

 obtuse ; the two lower spreading with a tapering, fleshy, channelled, 

 obtuse end. Labellum stalked, cordate, cucullate, three-lobed, con- 

 tinuous with the base of the columna ; the two lateral lobes shorter 

 than the middle one, membranous, veiny, with the anterior margin 

 crenated and callous ; the middle lobe ovate, abruptly acuminate, 

 obtuse, fleshy, crested in the middle with numerous fleshy appendages ;
