APOSTASIACEEH OF THE MALAY PENINSULA. 363 
MICROSACCUS, Blume. 
Microsaccus, Blume, Bijdr., p. 367, is a monotypic genus, 
which should probably be reduced to Saccolabiwm, from which 
it chiefly differs in habit. It has somehow got confused with 
the very distinct genus Adenoncos, which is a spurless plant 
allied to Luisia. 
M. savensts, Blume, l.c., is a tufted plant, with curved stems 
4 inches to 6 inches long, covered with dark green leaves, 
which are equitant and scalpelliform. The flowers are one or 
two in number, white, except for a yellow spot at the base 
of the lip, with rather large white bracts. The pollinia are 
four in number, equal, globose, on a slender narrow pedicel 
which bears a small lanceolate disc. The rostellum is rather 
long, tooth-shaped, and entire. The stigma transversely 
oblong. 
It is common in mangrove swamps and on rocks.
