tendency to condensed infructescences becomes more pro- 

 nounced. In Bleekrodea, ParatropMs, &c. the fruits are 

 drupaceous, and in the former enveloped in the perianth :

 becomes fleshy also, and since the dense heads of flowers 

 almost fuse as the drupes ripen, we have an infructescence 

 simulating the seterio of Eubus. In Coussapoa, &c. the 

 drupels, enclosed in their perianths, are aggregated 

 similarly on club-shaped or globoid receptacles. In Ple- 

 cospermum the fusion is still closer and the end of the
