Fii'st discovered by Mr. Gr. Ure Skinner in Guatemala^ afterwards by 



Warscewicz in Costa Rica and Veragua, by Galeotti, on porphyry 



rocks near Oaxaca, in Mexico^ at 7,000 — 8,000 feet elevation, and 



by Hartweg at the Hacienda del Carmen, in the same country. It 



lias tbence an extensive range in Central America, and like all 



widely distributed species, is found to be variable, especially in the 



labellum and its calli, from which circumstance it has received many 



names at the hands of botanists.* It is a curious and distinct plant, 



well distinguislied by its bottle-shaped pseudo-bulbs, its narrow, 



acuminate leaves, and the short, warty labellum of its flowers. 



E. virens. 



Encyclium. Pseudo-bulbs sub-conic, elongated, 3 inches long, invested 

 with a greyish membraneous sheath, but bare and furrowed when old, 

 di-triphyllous. Leaves linear, 12—15 inches long. Peduncles loosely 

 panicidate, 24 — 30 inches long, many flowered. Flowers an inch in 

 diameter; sepals and petals clawed, narrowly oval, pale yellow-green 

 stained with brown in the centre ; lip adnate to the column at the base 

 only, three-lobed, white with some purple markings in front of the 

 bilamellate callus, the lateral lobes oblong, oblique, sub-erect, the inter- 

 mediate lobe sub-quadrate, apiculate, spreading. Column clavate with 

 two small apical wings; green streaked with purple.

Abundant in Guatemala and Southern Mexico, whence it is 



frequently imported along with other more showy orchids from the 



same region; it was first discovered by Mr. G. Ure Skinner, in 



Guatemala. Epidendrum virens is nearly allied to E. alatum, from 



which it may be distinguished by its narrower leaves and more 



straggling panicles of smaller flowers of a duller colour. 



E. vitellinum. 



Encyclium. Pseudo-bulbs elongated, ovoid, or sub-conic, 1| — 2 inches 

 long, diphyllous. Leaves linear-lanceolate, 6 — 9 inches long, glaucous 

 green. Peduncles slender, nodding, covered with a glaucous bloom, 15 — 18 

 inches long, racemose along the upper half, 10 — 15 flowered. Flowers
