468 ORCHIDS. 
two or three flowers, which are 5in. across. The sepals 
are broad, the petals narrow, both being reflexed and 
shining, waxy white. The lip is 3in. long, solid and fleshy 
except at the base, where there is a short cavity with a 
pair of hook-like horns over the mouth; the apex of the 
lip is heart-shaped, and, except a few blotches of purple 
on the upper part of the lip, it is white, like the sepals; 
the column is gin. long, narrow, conspicuously winged 
near the top. This species is common in British Guiana, 
and is frequently met with in English collections. Syn. 
S. grandifiora (Lindley).

S. ecornuta.—Although rare in gardens, this species 
deserves mention here because of the exceptional form 
of its flowers. The pseudo-bulbs and leaves are large, 
deep’ green, and very like those of S. eburnea. The scape 
is short, enveloped in short, green, boat-shaped, over- 
lapping bracts, and is two-flowered. The sepals, which 
all point upwards, are ear-like, 2in. long, half as wide, 
concave, rather fleshy, and creamy white. The petals are 
similar to the sepals, but smaller. The lip is so remark- 
able in form that the species was at first supposed to 
be a monstrosity of some kind, and subsequently a new 
genus, Stanhopeastrum, was founded upon it by Reichen- 
bach. The terminal lobe and horns, characteristic of the 
genus, are in this species entirely absent, the lip being 
simply a fleshy, tuberculated sac, about 1}in. long and 
1in. wide, and the narrow aperture is partly covered by 
the short, fleshy column. The colour of both column and 
lip is bright yellow, deepening to dark orange at the 
base. The species was introduced from Central America 
in 1846.
