7. SURIANA, Linn. ; Benth. et Hook. f. Gen. PI. i. 313. 



Flowers hermaphrodite. Calyx 5-partite ; segments lanceolate, acute, im- 

 bricate, persistent. Petals 5, imbricate, equalling or shorter than the calyx. 

 Stamens 10(-8) ; filaments pilose below; anthers elliptical or rotundate, un- 

 appendaged (5 sometimes anantherous). Carpels 5, free ; ovaries pilose; 

 styles distinct, lateral, filiform ; stigmas obtuse. Ovules geminate, collateral, 

 ascending. Fruit-carpels 1-seeded. Seeds exalbuminous ; embryo hooked. 



A. maritime shrub. Leaves alternate, often crowded, liuear-spathulate, 

 obtuse or rather acute, entire, rather fleshy, veinless. Flowers in few- 

 flowered fascicles or corymbs at or near the extremity of the branches equal- 

 ing or shorter than the" leaves, yellow. 



Based upon a solitary species, frequent on the seacoasts of tropical countries. It want9 

 the bitterness generally characteristic of the family. 



.1- S. maritima, Linn. ; DC. Prod. ii. 91. A much-branched shrub, 

 with terete velvety or shortly pubescent branches. Leaves about 1 in. (|-1£

 sepals.

Flowers .hermaphrodite. Calyx small, 5-(3-4-)partite ; lobes rounded. 

 ratals as many, broadly imbricate, exceeding the calyx. Stamens 10 (or 

 •ewer), inserted under a thick fleshy, sulcatc or plicate, hypogynous disk ; 

 "laments filiform, unappendaged ; anthers small, rotundate. Ovary ovoid, 

 compressed, glabrous, inserted upon a broad disk ; style simple, terminal, 

 hliform or subulate ; stigma simple, obtuse. Ovules solitary. Fruit rather 

 'arge, drupaceous, 1-seeded ; pericarp woody or with a fleshy epicarp. Seed
