names, and such the changes of names, concerning which the 
public has a just right to complain; for they not only create 
intolerable confusion in nomenclature, but altogether mis- 
lead the lovers of plants, who upon the faith of works of 
apparent respectability are led to purchase, for the sake of its 
new name, and probably at a high rate, what they have 
already long possessed under some other name.

glauca, Knowles § Westcott, Floral Cabinet, t. 87. 
Mr. Barker, who imported this curious plant from Mexico, 
has favoured me with specimens, which enable me to state that 
it cannot be generically separated from the genus Epiden- 
drum. It is not a showy plant, the flowers being small, 
scentless, and green stained with dull purple. The drooping 
panicle is somewhat remarkable, and the glaucous covering 
of every part is much more so; but the species has no claims 
upon the attention of those cultivators who seek after orna- 
mental plants. 
57. BARKERIA elegans. Knowles & Westcott, Floral Cabinet, t. 49. 
An elegant little Mexican Orchidaceous plant, with taper- 
ing fleshy stems like those of a meagre Cycnoches, narrow- 
lanceolate acuminate membranous leaves, and a terminal 
inflorescence, in the form of a raceme of a few large bright 
pink flowers. It is well figured in the Floral Cabinet, and 
is one of the few plants which rival the Cattleyas in gaiety 
of appearance. It is however said to be difficult of cultiva- 
tion, and is at present of great rarity. The genus is well 
distinguished from Cattleya, to which it approaches most 
nearly, by its lip being flat and undivided, instead of cucul- 
late, and more or less ca three-lobed, as well as by its 
peculiar habit. As the genus has not yet found its way into 
books generally used by Botanists, a short technical character 
of it is added.
