ODONTOGLOSSUM. 425 



a half inches in diameter, the h'gulate aristate sepals and petals 

 sulphur yellow, with purplish blotches which finally become 

 suffused over their whole surface ; the lip is pandurate 

 cuspidate serrate, yellow with two or three reddish brown 

 fpots, and a bifurcate callus as in 0. crispum. The lip is 

 pointed as in 0. Andersonianum. It flowers during the 

 summer months. — New Grenada. 



0. bictomense, Lindley. — A well-known free-growing species 

 with oblong compressed pseudobulbs, bearing two or three 

 ensiform undulated leaves, and upright racemes of flowers, in 

 which the sepals and petals are green spotted with brown, 

 and the cordate acuminate lip lilac, or pink, or sometimes 

 white. The variety aJhum figured in Illustration Horticole 

 (3 ser. t. 91), has the sepals and petals wholly of a bright 

 chestnut brown, and the lip white, and that figured as splendens 

 in the same work (t. 449) has the sepals green and brown, 

 and the lip bright rosy lilac. The name africanum was given 

 by misadventure. — Mexico : Gtuitemala, 6,000 — 7,000 feet.

Syn. — Cyrtochilum bictoniense; Zygopetnlum africanum. 



0. bictoniense SUperbum, Williams. — A distinct free-growing 

 variety, much superior to the old form. The pseudobulbs 

 and leaves are light green, the spike erect many-flowered, 

 the sepals and petals dark chocolate brown, and the lip 

 large, purplish mauve marked with darker lines. It blooms 

 during the autumn months, and is a very desirable plant. — 

 Guatemala. 



O.blandum, richh.f. — This is a very fine species, somewhat 

 resembling a dwarf form of 0. ncevium. The flowers have a 

 honey-like fragrance, and are white with brownish crimson spots; 

 the sepals and petals are equal in size, cuneate-lanceolate 

 acuminate, creamy white beautifully spotted and freckled with 

 maroon crimson, and the lip which is of the same colour, 

 but much broader than in 0. naimim, has a bilamellate claw 

 with a broad ovate acuminate crispy blade. — New Grenada.
