ACINETA BARKERL 
column ; a column short, fleshy, and wingless ; and, finally, a pair of furrowed 
pollen masses, sessile in a narrow gland." In Peristeria Humboldti the upper sepal 
stands a little apart, so as to give a somewhat two-lipped appearance ; the lip has no 
articulation in the middle ; and the pollen masses are placed at the end of a narrow 
caudicle, terminating in a crescent-shaped gland; added to which the column is 
furnished with a pair of very broad wings. All these circumstances induced Dr. 
Lindley to separate Peristeria Humboldti and P. Barkeri under the name of 
Acineta ; in allusion to the immoveable, jointless condition of the lip. 
For the introduction of this magnificent species we are indebted to the late 
G. Barker, Esq., of Birmingham, whose collector, Mr. Ross, discovered it at Xalapa, 
in Mexico : it has since found its way into many collections. The specimen from 
which we made our drawing flowered in the stove of R. G. Lorraine, Esq., "Wel- 
lington Lodge, Carshalton, in October last. 
To grow well, it requires a powerful heat, plenty of water, and abundance of pot- 
room, with good drainage. In the season of rest it should be kept perfectly dry.
