394 NATURAL HISTORY OF PLANTS. 



(nearly of Spermacoce), 4-nierous; receptacle short obconical. Calyx 

 gamo23hyllous, short, 4-10-lobed ; lobes very unequal ; anterior and 

 posterior minute; 2 lateral much larger elongate, acute, persistent. 

 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 

 dry, much compressed parallel to septum ; valves 2, separable and 

 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 subericoid or subscoparious) ; branches slender virgate, 

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

 flowers ^ axillary in glomerules, spuriously verticillate. (Brazil.^) 



8. Gaillonia A. Kich.^ — 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 

 inferior elongate. Eigid branched shrublets, glabrous or more rarely 

 •variously clothed ; leaves opposite small rigid acute ; stipules connaAe 

 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.^) 



9 ? Crusea Cham, and Schlchtl.^ — Flowers (nearly of Spermacoce) 

 hermaphrodite, 4-merous ; calycinal lobes elongate, persistent ; 

 denticules sometimes intervening. Corolla funnel-shaped; tube
