XXXIV.—A REVISION OF THE GENUS CYCNOCHES. 
R. A. Roure. 
HISTORICAL. 
The genus Cycnoches for many years proved an inexplicable

to clear up the confusion into which the history of Cycnoches has 
en. 
The genus Cycnoches was established by Lindley in 1332 (Gen. 
and Sp. Orch. p. 154) upon a plant which had been sent from 
Surinam by Lance to Messrs. Loddiges, and which flowered in 
In 1836, when speaking of the curious behaviour of the genus 
Catasetum, Lindley remarked (Bot. Reg. sub t. 1951*) “1 am 
acquainted with the following example of this tendency in a very 
different genus. In August, 1836, Mr. Wilmer, of Oldfield, near 
Birmingham, sent me a specimen of a Cyenoches, which had broad 
petals, a short column, hooded and dilated at the apex, and a broad
