30 RUBIACEtE. Diodia. 



pubescence, and sprinkled with spreadino; hirsute hairs. Leaves about an 

 inch long, pale, the mar2;ins and midrib ciliolate-scabrous. Corolla 3-4 lines 

 long, white or pale red, s))rinkled with minute hairs under a lens. Anthers 

 linear-oblong. Capsule (usually but one in each axil) about 2 lines long, 

 much longer than the calyx-teeth. 



3. D. tricocca : perennial, much branched, depressed ; stems somewhat 

 hairy: leaves linear, with revolute margins; bristles of the stipules scarcely 

 as long as the fruit; flowers glomerate in the upper axils; corolla scarcely 

 exceeding the strongly hispid teeth of the calyx (often 3-lobed); the stamens 

 about the length of the lobes : stigma small, capitate ; fruit obovate-globose, 

 at first hispid, scarcely longer than the (4, rarely 5 !) conspicuous calyx- 

 teeth, separating into 3 chartaceous carpels. 



Texas, Drummond .' — Plant resembling a small state of D. teres, 3-4 

 inches high, appaiently ]jerennial. Leaves smooth above ; the margins and 

 midrib beneath somewhat hairy or his])id, at least when younn;. Flowers 

 and fruit much smaller than in the preceding; the latter scarcely half the - 

 size, and apparently alwaj's tricoccous, very hispid when young, as well as 

 the lanceolate teeth of tlie calyx, with stout bristles; but the mature fruit is 

 often nearly or quite glabrous ; the carpels roundish-obovate, flattened. — Our 

 specimens do not exhibit the corolla in good condition: but all the flowers 

 which we have examined present a 3-lobed corolla, 3 stamens, and a tricar- 

 pellary ovary, while the teeth of the calyx are 4, or very rarely 5, in number. 

 Probably these characters are not constant, but the species is very different 

 from any with which we are ac(iuainted. 



Subtribe 2. Putorie^:, DC. — Flowers distiuct. Fruit somewhat fleshy 

 or drupaceous, seldom bipartible.

Calyx-tube ovate ; the lobes of the 4-6 parted limb oblong-linear, acute, 

 pubescent. Corolla hypocrateriform, with a somewhat quadrangular tube ; 

 the lobes 4-6, lanceolate, revolute, valvate in ajstivation. Filaments in- 

 serted into the upper part of the tube : anthers linear, exserted. Style fili- 

 form, longer than the stamens : stigma emarginate. Fruit drupaceous, 

 obovate or roundish, 2-celled, crowned with the long erect segments of the 

 calyx, bipartible when mature ; the nuclei 1-seeded, cartilaginous, indehis- 

 cent. Seeds peltate, flat and furrowed on the face. Embryo straight : 

 cotyledons oval. — A suffrutescent and decumbent glabrous (West Indian) 

 plant ; with sessile somewhat rigid lanceolate leaves. Stipules sheathing, 

 many-parted. Flowers axillary, solitary, sessile, yellowish. Fruit yellow.

Key West, Mr. Blodgctl! Southern Florida, Dr. Hassler ! — Stem 6-10 

 inches long, branching from the base, stout and rigid; the branches quad- 

 rangular. Leaves mostly crowded towards the extremity of short branches, 

 about an inch long, somewhat coriaceous or fleshy, very acute and mucronate, 

 3-nerved. Flowers small. Fruit with a thin and rather dry pulp, separable 

 when ripe into 2 plano-convex portions, crowned with the long lanceolate 

 foliaceous calyx-teeth.
