164 BEGONIA HANIFFII. 



arc segregated, the females occupying the best places, the males 

 on lateral branches. The flowers are white with a slight amount 

 of the crimson pigment along the veins. The male flowers may 

 be | inch across and 1 inch i'rom top to bottom. The stamens are 

 about 120 in a globose, cluster, not having the connective extended. 

 The female flowers are 5-merous, about 4 in. across. The style 

 bifurcates close to the base, and each half with a considerable 

 amount of fullness ends in a dull yellow typically marginal stigma. 

 The ovary has two cells with the placenta in each as two plates. 

 The wings of the fruit outside these two cells make nearly equi- 

 lateral triangles; but the unpaired wing is much elongated, and 

 slightly hooked at the point. The surface of the capsule before 

 maturity is somewhat mealy by reason of sloughing cells.
