66 NATURAL HISTORY OF PLANTS. 



1-spermous ; testa of descendent seed thin ; albumen farinaceous 

 or fleshy, cox^ious, scanty or 0; cotyledons of straight embryo, plano- 

 convex ; radicle terete superior. — Glabrous or more rarely rather 

 pubescent shrubs; leaves alternate, simple, entire; stipules intra- 

 petiolar (in exceptional cases often imbricated or aphyllous) ; flowers 

 in axils of leaves, sometimes in scales of aborted ones), cymose or 

 solitary. (JU hot regions trop, and subtrop.) See p. 49. 



7. Aneulophus T3enth. — Flowers nearly of Eruthroxtjlon ; petals 

 5, traversed by interior prominent rib, deciduous. Stamens 10 

 {oî Erythroxylon), Germen 3, 4-locular ; styles 3, 4, more or less high 

 connate, stigmatiferous subclavate at apex ; ovules in each cell 2, 

 collaterally descendent. Drupe; putamen 1 -4-locular, 1-4- 

 spermous ; seeds . . . ? — A glabrous shi'ub ; leaves opposite enth'e ; 

 stipules intrapetiolar short, comiate ; flowers axillary cymose ; 

 pedicels very short, bracteolate at base. {Trop. W. Africa.) See p.

IV. HOUMIKIE^. 



8. Houmiri Aubl. — Flowers regular hermaphi-odite ; receptacle 

 short convex. Sepals 5, free or connate at base, imbricated more 

 rarely connate in calyx high gamophyllous or very shortly 5-dentate. 

 Petals same in number, alternate, contorted or imbricated, deciduous. 

 Stamens 10-co , all fertile, or the alternate sterile, conuate at base 

 or more rarely free ; anthers introrse sometimes versatile ; cells rather 

 large with connective scarcely or more or less long apiculatc, or more 

 usually smaller, and remotely inwardly at base, adnate to thick fleshy 

 compressed subconical or subpyi-araidal connective, longitudinally 

 rimose. Germen fi'ee, surrounded at base by hypogynous annular 

 or cupular disk, subentire truncate, dentate, lobed, or composed of 

 linear distinct glands ; cells 5, alteruipetalous, or more rarely 

 G-8 ; style simple, stigmatiferous at apex iisually slightly dilated, 

 entire or minutely dentate. Ovules in cells 1, 2 descendent ; funicle 

 unequal ; raicropyle extrorse superior. Fruit drupaceous, flesh often 

 thin or coriaceous ; putamen ligneous or very hard bony, often resi- 

 nous-pitted within. Seeds in cells solitary or 2-nate, and separated 

 obliquely by a septum ; albumen fleshy ; suj^erior radicle of straight 

 embrj'o, often longer then cotyledons. (South trop. America, trop. 

 West-Africa). See p. 51,
