ODONTOGLOSSUM HASTILABIUM, Lindley, Orchid. Linden. n. 84; Hooker, Bot. Mag. t. 4272; Pescatorea, t. 11. 
Habitat in Nov. GRANADA: Tesqua, in the province of Pamplona, at the elevation of 2500 feet, April, Zinden; on the road from 
Santa Martha to the Sierra Nevada, Purdie; Ocaña, January, 5-6000 feet, Schlim, Wagener, Blunt. 
DESCRIPTION, 
PsEUDOBULBS compressed, ovate, 3 to 6 inches long, bearing 1 or 2 oblong, leathery Leaves, not more than a third the 
length of the scape. Bracrs boat-shaped, acuminate, equal in length to the ovary. Soupe very robust, from 2 to 6 
feet high, panicled, bearing from 20 to 100 flowers. Srpars and Peras li fo 2 inches long, linear-lanceolate, 
acuminate, slightly waved at the margin, of a pale-green, barred with numerous lines of dark-red or purple. Lip 
halbert-shaped, purple at the base, but white in its upper portion, which is of a roundish-ovate form, pointed at the 
extremity ; its crest consists of 2 outer and 2 interior plates, the taller stretching forward beyond the former, 
with a linear-oval callosity in the centre. COLUMN expanding at its base on either side into an infleæd membrane. 
As this stately Odontoglosswm is met with at a much lower elevation than any of its congeners, it is constitutionally 
less impatient of heat, and has therefore been able to accommodate itself to artificial conditions under which others of 
its race in former years have pined and died. But although in some parts of New Granada it descends as low as 
2500 feet, its more frequent range is 2000 feet higher up the mountains, and it is in such situations that it attains 
its greatest luxuriance and beauty. Some imported specimens that I was fortunate enough to see last year (1864) 
at the Clapton Nursery, whither they had been sent by Mr. Blunt, had flower-stems half an inch thick and fully 
6 feet high. These were gathered at an clevation of at least 4000 feet above the sea-level and, as they arrived in 
excellent condition and have been extensively distributed, 1 have little doubt we shall ere long see cultivated specimens 
that may vie with the wild ones in stature and magnificence. Its flowering season is the spring or early summer. 
The figure was taken in May last from a plant in Mr. Rucker’s collection where it is grown at the coolest end of 
the Cattleya-house.
