Spermacoce. tetrandria monogynia. 367 



Knoxia corymbosa. Linn. sp. pi. ed. Willd. \.p. 582, which 

 he considers as Gcerttier's K. stricta, appears to me to be 

 this plant. Indeed the two genera Spermacoce and Knoxia 

 differ so little from one another as to induce me to think one 

 of them might be spared. 



2. S. teres. R. 



Shrubby, erect, round, villous. Leaves opposite, remote, 

 lanceolate, entire, villous. Corymbs terminal, decompound, 

 alternate ; divisions becoming spikes when in seed. Stamens 

 erect, but hid in hairs. Style twice the length of the corol. 



Knoxia umbellata, Banks. Herb. 



Found by Dr. Buchanan in the woods of Koorg, from 

 whence he sent the seed to the Botanic garden, where the 

 plants thrive well, and blossom during the rainy season. 



Stem erect, perennial, round, while young villous. Branches 

 opposite, a little inflected, round and villous, height of the 

 whole plant about three feet. Leaves opposite, short-petiol- 

 ed, lanceolate, downy, entire ; length from two to four inches 

 high. Connectiny membrane with several erect, filiform di- 

 visions; when they accompany the divisions of the inflores- 

 cence, they are more numerous, and may be called an involu- 

 cre. Corymbs terminal, brachiale, with the ultimate divisions 

 lengthened into short spikes by the time the seeds are ripe. 

 Corol, mouth of the tube shut with much long white hair, 

 which entirely conceals the large, erect anthers lodged 

 amongst it. Style erect. Stigma two-cleft with divisions 

 involute. 



Obs. This has much the habit of Hedyothjruticosa, but 

 differs widely in the stipules, (even if the pericarp of that 

 plant should be that of a Spermacoce,) and in the form of the 

 stem and branches. It is also very like S. sumatrensis, but 

 there the branches are four-sided, here perfectly round ; there 

 the tube of the corol is smooth, short and gibbous, here cylin- 

 dric, and shut with hairs ; finally the capsule is there biparti- 

 te, opening from the base, with oblong brown seed, in reali-
