Spermacoce. tetrandria monogynia. 369 



opposite, and like the stems, whole height about three feet. 

 Leaves opposite, sub-sessile, lanceolate, smooth, entire ; from 

 one to three inches long. Connecting membrane divided into 

 several subulate segments. Corymbs terminal, compound 

 and decompound. Flowers numerous, large, pale pink. 

 Bractes small, and at the divisions of the corymbs chiefly. 

 Calyx one of the four segments large, all the segments per- 

 manent. Corol funnel-shaped, before expansion the apex is 

 large, with four horns; after expansion these projections form 

 a conical knob under the apex of each segment. Month of 

 the tube bearded. Filaments short ; anthers linear, just 

 within the tube. Germ two-celled, with one seed in each, 

 attached to the top of the partition. Style longer than the tube 

 of the corol. Stigma bifid. Segments revolute. Capsule ob- 

 long, crowned, two-celled, two-valved ; valves keeled on the 

 back. Seed solitary, longitudinally grooved on the middle 

 of the inside. 



Qbp. It may be readily distinguished from S. teres (the 

 only species known, to me that it can be mistaken for) by its 

 smoothness, o-reater size of the flowers, and the segments of 

 their borders being enlarged with a conic knob on the outside 

 of their points. 



6. S. lineata. R. 



Erect, ramous, hairy. Leaves short- petioled, lanceolate, 

 acuminate, linear. Stipules triangular and shaggy. Heads 

 axillary on trichotomous short peduncles Stamina protrud- 

 ed. 



A native of the Moluccas. The lineate, hairy, very acute, 

 tapering leaves, long abaggtf triangular stipulse, and small 

 peduncled heads of axillary flowers, readily distinguish this 

 species from all the other East Indian species known to me. 



7. S. nana. R. 



Erect, simple, nearly round and smooth ; leaves petioled,
