 physocarpa). Semina in loeulis bina vel abortu singula, obovoidea, subglobosa vel 

 lentieularia, eirea hilum eallo humili vel erassiusculo notata vel eallo in strophiolum 

 infundibuliforme produeto appendieulata (Series IIL, Subser. 5.), arillo vero nuUo, 

 testa erustaeea vel eoriaeea, laevi, opaea vel in paueis splendente in nonnuUis lenti-
