 are found in tropical Asia and Africa, have opposite leaves accom-

V. HIPPOCRATE SEEIES. 



The flowers of Hippocratea 1 are closely analogous to those of 

 Euonymus, regular and hermaphrodite. The receptacle, more or less 

 flattened, bears a short calyx of five sepals, free, or united only at the 

 base, imbricated or nearly valvate, with five alternate petals, longer,
