422 ORCHIDS. 
are sometimes as much as 1i3ft. in length, with the upper 
surface of a dark green colour, profusely and irregularly 
mottled with greyish white; on the under side they are 
purple. The flower-scapes are from r}ft. to 3ft. long, and 
branch freely, bearing numerous flowers 24in. to 3in. in 
diameter. A single inflorescence is recorded as having 
carried 174 flowers. The sepals are obovate, and, like the 
larger and more rounded petals, are light mauve or rose, 
white at the margins. The side lobes of the lip are similarly 
coloured, the central one being usually paler, sometimes 
white, with the extremity dividing into two divergent horns ; 
at the base is a yellow callus, spotted with reddish brown. 
The species is variable in colour, but all the forms are 
exceedingly pretty. The roots form a notable feature of the 
plant, being flat and rough, and produced in great abundance. 
It is said to have now become scarce in a wild state, so 
that in a few years it will probably be a much more valuable 
Orchid. It was introduced from the Philippine Islands in 
1860.

P,. Stuartiana.—A distinct and handsome species, which 
is deservedly becoming more popular every year. It 
occasionally displays the remarkable and, amongst Orchids, 
very unusual property of producing young plants on the 
roots. The leaves are oblong, obliquely notched at the tips, 
and from 6in. to 12in. in length; when young they are 
prettily marbled on the upper surface. In some forms the 
leaves become almost entirely green as they grow older; 
but in many the mottled surface remains fixed, and adds to 
the beauty of the plant. The flowers are borne on 
branching racemes, and are about 2in. across. The petals 
are rhomboidal, and more than twice the width of the oblong 
sepals; the lower half of the lateral sepals is of a pale
