from the direct rays of the sun, though the early morning sunbeams appear to be 
rather beneficial. 
ZYGOPETALUM BRACHYPETALUM. Native of Brazil. 
A handsome species with sword-like, lanceolate leaves, from three to five in 
number, which grow from the top of the oval, light green pseudobulbs (2 to 24 
inches high). Scape grows from the base of the pseudobulb and carries from two 
to five flowers, each from 2} to 3 inches in width, with stiff, oblong-obtuse sepals 
and petals, brown somewhat marbled with green, and a broad, roundish, notched 
lip which is white with blue-violet. At the base of the lip is a frill-like crest 
closely striped with blue. Flowers in midwinter and lasts some weeks. 
ZYGOPETALUM BURKEI. Native of British Guiana. 
A striking species with clustered, narrowly oblong, compressed pseudobulbs which 
become furrowed with age, and a pair of linear, lanceolate, acute leaves 9 to 12 
inches long. Radical flower scapes carry four or five flowers each 24 inches across, 
with oval-oblong sepals and petals whose margins are slightly reflexed. They are 
green with seven to nine longitudinal, chocolate bars sometimes broken into dots. 
Lip white with numerous crimson grooves and ridges. This species grows at an 
elevation of 6,000 feet on rocks in swamps on the side of the Roraima Mountains 
in British Guiana. It requires rather more warmth than most species and more 
moist conditions. Flowers in Winter and lasts three to five weeks. 
ZYGOPETALUM CRINITUM. Native of Brazil. 
A fine species often classified as a variety of Z. Mackayi. It has ovoid green 
pseudobulbs, wrinkled when old, which bear three lanceolate, strap-shaped, some- 
what plaited leaves. Flower scapes bear five to seven flowers each about 3 inches 
across. Sepals and petals are green barred with brown, the broad lip being creamy- 
white with hairy purple coloured veins. The disk has a small yellow semi-circular 
callus. Flowers in Autumn and lasts well. 
(Syn. Zyg. Mackayi crinitum.) 
ZYGOPETALUM DAYANUM. Native of Colombia. 
A species without pseudobulbs and growing in a tuft of oblanceolate, pointed, 
narrow leaves 10 to 15 inches long. Bloom is solitary, about 3 inches across. 
The fleshy sepals and petals are creamy-white tipped with pale green, the petals 
being smaller than the sepals and often without the green tips. Lip is white with 
crimson streaks and furnished with a semi-circular frilly crest of deep crimson. 
Flowers in late Autumn. Native of the Andes at a height of 6,000 feet.
