06 NATURAL HISTORY OF PLANTS. 



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

 or fleshy, copious, 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. {All hot regions trap, and suhtrop.) See p. 49. 



7. Aneulophus Benth. — Flowers nearly of Erythroxylon ; petals 

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

 (of 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 shrub ; leaves opposite entire ; 

 stipules intrapetiolar short, connate ; flowers axillary cymose ; 

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

 51.

8. Houmiri Axjbl. — Flowers regular hermaphrodite ; 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 lO-oo , all fertile, or the alternate sterile, connate at base 

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

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

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

 compressed subconical or subpyramidal connective, longitudinally 

 rimose. Germen free, surrounded at* base by hypogynous annular 

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

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

 6-8 ; style simple, stigmatiferous at apex usually slightly dilated, 

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

 unequal ; micropyle 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 ; superior radicle of straight 

 embryo, often longer then cotyledons. {South trop. America, trop. 

 West-Africa). See p. 51.
