Ordo parvus a Drownio eum Polygaleis comparatus precipue quoad capsule structuram, differt 
flore regulari, :xstivatione perianthii, ete. ; a Steetzio Sferculiaceis Lasiopetaleis approximatus, cum 
quibus :estivatione calycis et quodammodo habitu convenit, sed corolle sstivatione, staminibus, et 
gynecio discrepat; ab utroque Ordine insuper differt, Pittosporeis (imprimis Cheiranthere) ac- 
cedens, embryone in albumine copioso minimo.
