Our Catasetum trifidum and Dr. Lindley's Myanthus cernuus 

 were published respectively in the Bot. Magazine and in the 

 Gen. et Sp. Orchid, nearly at the same time, so that it is diffi- 

 cult to say which has the priority of name. It is, indeed, true 

 that the two are identical as to species ; and in the ' Botanical 

 Register,' published in 1834, Dr. Lindley quotes our plant as 

 a synonym to his Myanthus. There are some slight differences 

 indeed noticed above, which may justify its being considered a 

 variety; but as to the genus, Dr. Lindley himself, we believe, 

 has abandoned Myanthus as untenable. It has all the essential 

 characters of Catasetum, and now merges into that. 



Our original plant, and the first introduced into Europe, was 

 derived from Trinidad, and was sent by Mr. Lockhart ; but we 

 have since been informed that it was there received from Rio
