Spermacoce. tetrandria monogynia. 371 



lary, numerous, pale pink, very small, crowded together into 

 small round heads, on short peduncles, and pedicels, the whole 

 forming little, proliferous, villous umbels. Involucre and in- 

 volucels annular, villous, from three to six-parted. Calyx, di- 

 visions equal, acute, hairy. Corol funnel-shaped, hairy on the 

 outside, and in the throat of the tube ; divisions of the border 

 recurved. Stamens protruded beyond the mouth of the corol.

 tube of the corol. Stigma two-cleft, villous. Pericarp with

10. S. semierecta. R, 



Stem variously bent, but ascending, square. Branches 

 brachiate, alternately smaller. Leaves ovate. Flowers in 

 small, compact verticils. Stamens and style inclosed. Capsule 

 turbinate, hairy. 



A native, I suppose, of Sumatra, as the plant from which 

 this description is taken, sprung up in a bed, where earth 

 from that Island had been thrown, and in one year was about 

 a foot and a half high. 



The lower branches brachiate ; the superior often solitary, 

 they are all very exactly four-sided with angles sharp and 

 somewhat hispid ; in other respects they are very smooth. 

 Leaves opposite, with smaller ones in their axills, short-peti- 

 oled, acuminate, entire, very slightly scabrous, particularly 

 the margins, with nerves and veins on the underside. Connect- 

 ing membrane divided into several filiform portions. Flow- 

 ers numerous, very small, white, sessile, collected into small 

 compact, round verticils. Corol, divisions of the border 

 bearded in the centre. Antliers within the tube. 



U.S. scabra. Linn. sp. pi. ed. Willd. i. 572. 



Annual, diffuse, round, hairy. Leaves opposite, sessile, 

 round, obovate, the hairy margins much curved, and some- 

 what curled. Flowers axillary, sessile. Stamens and style 



erect.
