478 ORCHIDS. 
T. alba.—This is a free-growing species, with terete 
tapering stems 2ft. to 3ft. high, clothed with pale green 
leaves, which are narrowly oblong, pointed, about 6in. long, 
and glaucous underneath. The flowers are borne in a 
pendulous cluster at the apex of the stem, a dozen or more 
together; each is from 3in. to 4in. in diameter when fully 
expanded; they are frequently, however, kept half-closed by 
the large, boat-shaped bract at the base, but this can be 
remedied by carefully slitting the bract with a sharp knife. 
The sepals and petals are white, oblong-lanceolate. The 
sides of the lip inclose the column; the central part is 
expanded, wavy at the margin, the white ground being 
faintly marked with pale purple. Introduced from Nepal 
about 1841; it is also found in Burmah. The flowers 
are produced in June. Syn. Phazus albus.

T. Bensoni#.—A very elegant and beautiful species, 
similar to T. alba in general appearance. The stems are 
2ft. to 3ft. high. The leaves are pale green on the upper 
surface, glaucous beneath. The drooping flowers are pro- 
duced on short, terminal racemes of about ten to twelve; 
each bloom is between 4in. and 5in. across. The sepals 
and petals are alike, spreading, narrowly oblong, bright 
red-purple, of varying depth of shade, but always paler 
towards the base. The lip is trilobed, rich magenta-purple 
on the front lobe, which is broadly oblong, frilled, unevenly 
lobed, and toothed at the margin; the side lobes meet 
over the column. Introduced from Rangoon in 1867. It 
flowers in July. Syn. Phazus Bensoniz.
