upon the unciform axes. Seven or eight species! of this genus are 
known, principally natives of the warmest regions of Asia and 
Malaysia. One or two species inhabit tropical Western Africa. 

III. LOPHIRA SERIES. 
Lophira’ (figs. 217-221) has regular hermaphrodite flowers. Upon 
the narrow flat receptacle is inserted a subhypogynous perianth, 
composed of five sepals, subequal, free, or nearly so, and quin- 
Lophira alata.

cuncially imbricated, and of five alternate petals, contorted or 
imbricated in the bud. The androceum is formed of a very con- 
siderable number of stamens. The filaments are free except at the 
base, and surmounted by an anther with two equal linear cells, 
introrse and dehiscing longitudinally.® The gynæceum is free; it is 
formed of a one-celled* conical ovary, terminated by a style with two

which has caused it to be possible at a certain 
age to consider them as pores. 
4 There are fonnd, it is true, two parietal 
rudiments of vertical partitions corresponding on 
each side to the interval of two neighbouring 
series of ovules; but they are little prominent 
in the cavity of the ovary. Nevertheless, with 
the two branches of the style, they would seem 
to show that the gynæceum is really dicar- 
pellary,
