UA | |J. LXIX. LYTHRARIEX. 
Species ad 250, plerz:que regionum tropicarum utriusque orbis imprimis Americe incole, paucee 
per regiones temperatas utriusque orbis latissime disperse. 
Lythrariee pluribus Ordinibus per. genera. varia tam arcte connectuntur ut difficillime characte- 
ribus certis dignoscere possumus. Ab Onagrareis differunt ovario libero, a Haloragiis, quibus - 
genera Didiplis Quartinia et Hydrolythrum habitu accedunt, distinguuntur ovario libero ovulisque 
nuierosis ;- a RAizophoreis discedunt ovulis oo et defectu stipularum ; a Myr£aceis etiam in gene- 
ribus fcis siepissime dignoscuntur calycis lobis valvatis, id quod in illis observatur in perpaucis 
tantum generibus disco staminifero lato aliisque notis a Lythraricis abunde distinctis. Melastomacec, 
pluribus notis Lythrarieis affines, facile differunt staminum indole. .
