 Lobes of short funnel-shaped corolla 4, valvate. Stamens short, 

 enclosed, inserted in throat. Germen 2-celled, crowned with.epigynous 

 disk and short style, emarginate or 2-dentate at apex ; ovule in cell 1, 

 peltately inserted on septum; micropyle extrorsely inferior. Fruit

 crowned with half the calyx. Seed in each much compressed, 

 orbicular-elliptical ; hilum punctiform central ; albumen copious ; 

 embryo terete elongate ; cotyledons ovate-acute ; radicle inferior. — 

 Shrubs (oftener subericoidor subscoparious) ; branches slender virgate, 

 4-gonal ; leaves linear subsessile connate ciliate sheathing stipules ; 

 flowers ^ axillary in glomerules, spuriously verticillate. {Brazil.") 



8. Gaillonia A. Rich.^ — Flowers hermaphrodite; receptacle ovoid, • 

 enclosing adnate germen. Calyx short, sometimes dilated, unequally 

 2-7-crenate or dentate ; teeth sometimes growing to bristly plumes 

 (Jauhertia). Tube of corolla often elongate; lobes 4, 5, valvate. 

 Stamens same in number, inserted in hollows or throat, enclosed or 

 exserted. Germen 2-celled ; disk scarcely perceptible ; branches of 

 slender elongate style 2, short recurved. Ovules attached to septum ; 

 micropyle extrorsely inferior. Fruit 2-coccous; cocci indehiscent. 

 Seed oblong ; hilum ventral ; albumen hard ; radicle of axile embryo 

 iuferior elongate. Eigid branched shrublets, glabrous or more rarely 

 variously clothed ; leaves opposite small rigid acute ; stipules connate 

 in a sheath with leaves, more rarely remote from leaves, very small 

 or 0; sheath entire or divided into 2 bristles or spines; flowers* 

 solitary, cymose or in a spicate cyme.^ {West. Asia, north. Africa.^)
