As stated by Mr. Rolfe in the Kew Bulletin, Catasetum 
Lemosii is the C. roseum of Don Barbosa Rodrigues, who 
appears to have been unaware, when he published it in 
1877, of a previous C. rosewm having been described by 
Reichenbach in the Gardener's Chronicle in 1872. For 
this reason Mr. Rolfe has substituted for this the name 
Lemosii, after Dr. Lemos, Superintendent of Schools 
in the Province of Para. In another respeet the change 
of name is welcome, for neither in Don Rodrigue’s drawing 
of the plant (of which there is a copy in the Kew 
Library) nor in specimens cultivated at Kew, are the flowers 
really rose-coloured. Little dependence, however, can be 
placed on colour in this, as in many other Orchids ; for 
in Mr. Rolfe’s description the sepals and petals are 
brownish flesh-coloured, ultimately becoming tawny- 
yellow; whereas they are rather greenish-yellow in the 
specimen here reproduced. According to Don Barbosa’s 
description the sepals and petals should be rosy, the tip 
green behind, and orange-yellow in front. 
Catasetum Lemosii is a native of the Ile de Marajo, 
Province of Para, at the mouth of the Amazons, whence 
plants were procured by Dr. Lemos, who gave them 
NovemBER I1s1, 1895.
