^19. CATASETUM Russellianum ; pseudobulbo elliptico magno, foliis lato- 

 lanceolatis, racemo amplo, Jabello submembranaceo antice inflato ore 

 contracto margine anteriore producto undulato fimbriato disco mem- 

 brana cristato, columna nuda (ecirrhosa). Hooker in Bot.Mag. t. ^777. 



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. 

 It is very near Catasetum laminatum, a Mexican species. 



20. EPIDENDRUM falcafwn. Lindley in Taylor's Annals of Natural His- 

 tory, Feb. 1840. (E. ParJdnsoniaimm, Hooker in Bot. Mag. Feb. 1840. 

 t. 3778.) 



A very fine species of the caulescent tribe of this extea- 

 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. 



21. ONCIDIUM Insleayi (Barker in litt.) ; pseudo-bulbis ovatis compressis 

 diphyllis, foliis erectis coriaceis oblongo-ensiformibus subundulatis apice 

 recurvis racemo simplici ei-ecto rigido brevioribus, sepalis j)etalisque ob- 

 longis subsequalibus undulatis infimis basi connatis, labello obovato 

 retuso basi sagittate disci tuberculo apice depresso dilatato bilobo utrin- 

 que in medio unidentato lamellaque unica retrofracta aucto, columnse 

 alls cirrbatis. 



This beautiful Oncidium is a native of Mexico, w^hence 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 difi'erent, 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 Orchidacese 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
