ACINETA BARKER! 
(Mr. Barker’s Acineta.) 
Clast. Order. 
GYNANDRIA. MONANDRIA. 
Natural Order. 
ORCHIDACEiE. 
Generic Character.— Perianth fleshy, spreading. 
ipals concave, joined at the base, hence forming a 
lonophyllous calyx. Petals resembling the sepals, but 
ither smaller. Lip very fleshy, continued from the 
ongated base of the column without any articulation 
1 the middle, three-lobed. Column erect, with a pro- 
ofing rounded lobe or wing on each side. 
Specific Character. — Pseudo-bulbs very long, broad- 
ovate, deeply furrowed, with the ridges wrinkled, 
f a dark-green colour. Leaves from the summit of the 
seudo-bulbs, two feet and more long, broadly lanceo- 
ite, tapering at each end, membranous, plaited. Scapes 
endent from the base of the pseudo-bulb, a foot or 
more long, lax, bearing flowers in a raceme almost to 
the very base, which latter is sheathed with several 
brown scales. Flowers subglobose, of a rather full 
yellow colour, the unexpanded ones tinged with green. 
Sepals and petals very concave, obtuse, nearly equal, 
scarcely spreading. Lip small, articulate upon the 
elongated base of the column, deeply three-lobed ; 
lateral lobes large, erect, embracing the column ; 
middle one much smaller, refuse; within is a large 
gland spotted with red. Column semicylindrical ; its 
wings short ; the back slightly downy, 
Synonyme. — Peristeria Barkeri. 
Two very distinct species of this superb genus were introduced to this country a 
sw years ago, one of which has been named A. Humboldti, and the other (our 
•resent subject) A. Barkeri. The first of these Dr. Lindley has clearly proved to 
e identical with the Anguloa superba of Humboldt, Bonpland, and Kunth ; and in 
843 he gave a beautiful figure of it in the “ Botanical Register, ” t. 18, under 
he name of Peristeria Humboldti. In 1845 Sir W. Hooker gave, in the “Botanical 
lagazine,” t. 4156, a plate of a magnificent variety of that species which he named 
° eristeria Humboldti fulva. The latter gentleman also has given a description 
nd a fine plate in the “ Botanical Magazine,” t. 4203, of our present subject, under 
he name of Peristeria Barkeri. 
On a recent examination of the genus Peristeria by Dr. Lindley, and by carefully 
tudying its species, he has discovered that, in one or more particulars, the above 
wo species essentially differ from the genus under which they were placed. “ The 
ype of the genus Peristeria is the * Dove plant ’ of Panama, which has an erect 
cape ; globose, fleshy flowers ; equal and regular sepals, united at the base, but 
‘rejecting forwards with the chin usual in the Maxillaridous section ; a lip continuous 
vith the column, fleshy, arrow-headed at the base, distinctly articulated in the 
niddle, and having its epichilium undivided and bent down over the face of the
