1 The name and synonymy of this species have been altered in the lijrht of Professor Urban's 

 recent critical work upon the group (.see Enf;l. Jahrb. xxi. 571). It seems best, however, to retain tlie 

 genus XnnthoTi/liim in its conn)ri'lipnsive sense, as interpreted i>y Dr. Gray. 



2 The nearly related A', vmnryinalum, Sw., of Jamaica, to which Dr. Gray referred this plant, 

 appears to be distinct, as pointed out by Urban, 1. c. 590-592, since it has ovate rather than obovate 

 leaves and (ace. to Urban) smoother fruit.
