66 NATURAL HISTORY OF PLANTS. 



1-spermons ; testa of descenclent seed thin ; albumen farinaceous 

 or fleshy, copious, scanty or 0; cotyledons of straight embryo, plano- 

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

 pxibcscent shrubs; leaves alternate, simple, eutir-e; 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 Irop. and suhtrop.) See p. 49. 



7. Aneulophus Benth. — Flowers nearly of ^r_y;'/»ur// /oh ; petals 

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

 [oi Erythroxylon). German 3, 4-locular ; styles 3, 4, more or less high 

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

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

 spermous ; seeds . . . ? — A glabrous shrub ; leaves opposite entii-e ; 

 stipules intrapetiolar short, connate ; flowers axillary cymose ; 

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

 51. 



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 lO-oj , 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 subpp-amidal connective, longitudinally 

 rimose. Gormen free, surrounded at base by hypogyuous 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 sui^erior. Fruit drupaceous, flesh often 

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

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

 obliquely by a septum ; albumen fleshy ; superior radicle of straight 

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

 Wcsl-Jfrica). See p. 51.
