gati, undique stigmatosi v.fascia papillosa stigmatosa scepissime spirali cincti, interdum

tropa. JFructws capsularis, loculicide (rarius septicide) dehiscens, rarius bacca carnosa 
irregulariter rupta, 3-, rarius 2-, 4- v. oo-locularis, oo-sperma. Semina numerosissima, - 
minuta, oblonga v. subcylindrica ; testa reticulata ; albuminis stratum tenue v. 0. Embryo

australi maxima copia crescentes, in ins. Oceani Pacifici rari, in Australin hactenus non repertse. 
Ordo nulli, Datisceis exceptis, arcte affinis, sed, si gepta ovarii spuria et e placentis oriunda existi- 
mas, Begoniacee cum variis inter Ca/ycifloras Ordinibus parietosis connectuntur. Lindleyus primus, 
et non sine ratione affinitatem cum Cucurbifaceis indicavit, ctsi perianthia stamina seminaque discre- 
pant. Antherw eas Ceratiosicyi inter Passifloreas referunt, semina Loasacearum. — Sazifragieis e 
tribu Zydrangiearum accedunt seminibus notisque paucis aliis, et flos Hillebrandie Sazifragam in 
mentem revoeat ; hujusmodi tamen characteres analogiam potius quam aflinitatem indicant.
