not tricolor, of which I have no description, because I have 

 two Httle bulbs of it, and its leaves are bright green ; but it 

 may have been named in the Petersburg Acts. I received it 

 from Mr. Kotschy, who collected it on Mount Elburz. It 

 flowered at Spofforth in April, 1844.-17. H. 



40. The Species of CATASETUM. 



This genus was founded by Louis Claude Richard upon 

 two plants from tropical America, one of which he called 

 C. macrocarpon, the other C. maculatum. Among the pecu- 

 liarities of the genus were two long feelers or cirrhi directed 

 downwards from the column into the cavity of the lip, and a 

 large fleshy helmet-shaped lip. 



As soon as the attraction of European gardeners began to 

 be turned to the cultivation of tropical Orchidacea?, other 

 species of the genus were made known, and now it has become 

 a very considerable group, the greater part of which is scat- 

 tered through various writings. In the course of gathering 

 together these materials certain plants were obtained, which 

 appeared to form distinct genera ; one was called Myanthiis^ 

 the other Monachanthus. Myanthus was thought to be dis- 

 tinguished by having a flat lip, and Monachanthus by want of 

 feelers on the column. But, strange to say, both these flowers 

 were afterwards ascertained to be monsters of genuine Cata- 

 seta, as was fully explained at tab. 1951 of the Botanical 

 Register. 



The following are, we believe, all the Cataseta now on 

 record, divided into two sets, one of which has a plane lip, 

 and answers to Myanthus ; the other a helraetted lip, answer- 

 ino- to the orisfinal Catasetum.
