Species v. forms adhue descriptz ultra 2200 numerantur, quarum perplurime falsw sunt, et sub 
nostra recensione 1200 restant. Ordo per totum fere orbem dispersus; limites vegetationis phze- 
nogamici in regionibus polaribus montibusque altissimis attingit. Maxima copia generum et spe- 
eierum Europam australem Asiamque Minorem incolunt; in tropicis, in America extratropica et 
boreali-temperata rarius oceurrunt. 
Crucifere inter Papaveraceas (Sect. Fumarieas) et Capparideas medis, ab utroque ordine peri- 
anthio eruciformi staminibusque tetradynamis facile distinguendz sunt. Genera pleraque in Ordine 
naturalissimo characteribus levioris momentu separantur.
