 dular. Basal leaves oblong to oval, 1-2.5 cm. long, 0.5-1.5 cm. broad, shallowly pinnately 

 lobed, the petioles slender, often exceeding the blades ; cauline leaves few, subtending the in- 

 florescence, like the basal or entire ; flowers few, pedicellate in lax simple cymes, the cymes in

6. MILTITZIA A. DC. Prod. 9: 296. 1845. 



Low, diffuse, ascending, or erect, usually glandular-viscid annuals from slender tap- 

 roots. Leaves alternate or some of them opposite, the basal usually forming a rosette, 

 petiolate, entire to pinnatifid or pinnate. Flowers in short and compact to filiform and lax, 

 simple or branched terminal scorpioid cymes, pedicellate. Calyx divided nearly to the 

 base, the lobes subequal. linear or oblong to oblanceolate. Corolla yellow or purplish- 

 tinged (whitish in one species), withering-persistent and enclosing the capsule, campan- 

 ulate, shorter or longer than the calyx, shallowly to more deeply lobed. Stamens included, 

 subequal to unequal, equally inserted on the base of the corolla-tube, the anthers oval to 

 orbicular. Style persistent, usually included in flower, often exserted after anthesis, 2-cleft 

 or subentire. Mature capsule unilocular or nearly bilocular by the intrusion of the pla- 

 centae, oblong to nearly globose, acute, loculicidally dehiscent. Ovules several to numerous 

 on the two prominent, linear placentae, laterally attached but nearly sessile. Seeds oblong
