as: CATASETÚM Russellianum ; pseudobulbo elliptico magno, foliis lato- 
lanceolatis, racemo amplo, labello submembranaceo anticé inflato ore 
contracto margine anteriore producto undulato fimbriato disco mem- 
braná cristato, columná nuda (ecirrhosá). Hooker in Bot. Mag. t. 3777. 
A large species with green flowers, a little relieved by 
the greater whiteness of the labellum ; sent from Guatemala 
by Mr. Skinner to the late Duke of Bedford. The labellum 
is described by Sir W. Hooker as being almost membranous. 
Itis very near Catasetum laminatum, a Mexican species. 
20. EPIDENDRUM falcatum. Lindley in Taylor’s Annals of Natural His- 
tory, Feb. 1840. (E. Parkinsonianum, Hooker in Bot. Mag. Feb. 1840. 
t. 3778.) 
A very fine species of the caulescent tribe of this exten- 
sive genus, with fleshy branching short stems, long channelled 
falcate leaves, and large yellow flowers, springing from within 
a long pale yellowish-green membranous spathe. In Sir Wm. 
Hooker’s figure only two flowers are represented, but in my 
wild specimens there are four or more to each spathe. ‘The 
latter were found by Mr. Hartweg among rocks and loose 
stones, at the Hacienda de Santa Ana, in the neighbourhood 
of Oaxaca, flowering in May. The plant is not very uncom- 
mon in collections of Mexican epiphytes. 
91. ONCIDIUM Insleayi (Barker in litt.) ; pseudo-bulbis ovatis compressis 
diphyllis, foliis erectis coriaceis oblongo-ensiformibus subundulatis apice 
recurvis racemo simplici erecto rigido brevioribus, sepalis petalisque ob- 
longis subsequalibus undulatis infimis basi connatis, labello obovato 
retuso basi sagittato disci tuberculo apice depresso dilatato bilobo utrin- 
identato lamellâgue unica retrofractá aucto, columns 
que in medio uni 
alis cirrhatis. 
This beautiful Oncidium is a native of Mexico, whence it 
was imported by George Barker, Esq. of Birmingham, who 
has named it after Mr. Insleay, his gardener. It has flowers 
similar in size, colour, and spotting, to those of O. Papilio, 
but their form is quite different, and they are produced upon 
a stiff erect spike. It is among the finest of the genus, and 
will form one of the plates in Mr. Batemau's magnificent 
work on the Orchidacez of Mexico and Guatemala. 
22. BROUGHTONIA aurea; sepalis linearibus acutis, petalis conformibus, 
labello ovato convoluto acuminato. 
A native of Mexico, in the neighbourhood of Valladolid, 
whence it was obtained by Mr. Barker.—- 'The flowers are
