above indicated, was received from Mr. Heatherly at the 
same time. It differs nothing in foliage; but the divisions 
of the flower are much narrower, of a bright copper-colour 
-towards the base, and scarcely at all varied with spots. 
Oncidium is the most distinctly characterised of all the 
genera of epiphytous Orchidee: the spreading segments of 
the perianthium; the 3-lobed labellum, of various figures, but 
always having a fleshy crested discus; the winged columna, 
and the two pollen masses hollowed out at their back, and 
attached to a slender pedicel, together with the radical inflo- 
rescence,—afford characters which have never yet been ma- 
terially affected by the discovery of Transition Species. We 
may, however, take this opportunity of remarking, that the 
genus Fernandesia of the Flora.Peruviana, of which the Lock- 
hartia elegans of the Botanical Magazine, fol. 2715, is a spe- 
cies, and from which Pachyphyllum of M. Kunth is probably 
not distinguishable, differs from Oncidium in little besides 
its axillary inflorescence, imbricated stems, dilated bractez, 
and solid pollen masses. By the latter character it is 
neatly distinguished from Oncidium, which has hollow 
pollen masses cut open at the back. 
Of Fernandesia there are three, if not a greater number 
of species, in our gardens. Mr. Lambert is the fortunate 
possessor of some from Pavon; and we were a few months 
ago obliged by a sight of fresh specimens, in flower, of 
a species perhaps not different from F. subbiflora, with 
which we were favoured by Messrs. Loddiges. 
~ Bulbs in clusters, compressed, two-edged, one-leaved. 
Leaves thick, fleshy, pale yellow, nearly erect, oval, obtuse 
with a point, generally concave at base, and split here 
and there at the margin. Scape about a foot and half 
high, round, purple. Panicle many-flowered, very much 
diyaricating, flexuose. owers large, yellow, rather olive- 
coloured, except the lip. Segments of the perianthium 5, 
separate, spreading, spatulate-oblong, nearly equal, spotted 
with crimson towards the base. ip yellow, flat, 3-lobed, 
crenulate, spotted; the lateral lobes rounded, deeply 
cordate at base, the intermediate one smaller, emarginate, 
often folded together.
