tibus et sursum in rostro elastice revolutis, v. 2—co-spermis dorso loculieide dehiscentibus 
valvis eum axi persistentibus v. ab eo elastice desilientibus, parte placentifera semper cum 
axi persistente; nune in coccos 3-5 indehiscentes induratos ab axi secedens; v. rarius bac-

latim oo-flori, rarius cymiferi v. racemiferi. Flores stepe speciosi. Sepala persistentia v. 
rarius decidua. Petala colore vario, sepius fugacia, rarius scarioso-persistentia. 
Species ad 750, per regiones temperatas subtropieasve utriusque orbis disperssz, magna copia in 
Africa australi vigentes, inter tropicos paueze nisi in regionibus montanis editioribus ; in Australia 
perpauez observantur. 
Ordo Rutaceis Zygophylleisque affinis, e& eum illis ovario lobato convenit, sed fructus axi placen- 
tifera persistente, v. carpellis distinetis indehiscentibus induratis distinguitur. Genera nonnulla 
Lineis quoad petala et stamina accedunt, sed ovario lobato et axi persistente dignoseuntur. Habitus 
et folia etiam longe diversa.
