Spermacoce. tetrandria monogynia. 873 



Knoxia corj/mbosa, Linn. Sp. PL ed. JVilld. i. p. 582, which he 

 considers as Gccrtner^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, ei ect, round, villous. Leaves opposite, remote, lanceo- 

 late, entire, villous. Corymbs terminal, decompound, alternate : di- 

 visions becoming spikes when in seed. Stamois erect, but lud in 

 hairs. Style twice the length of the corol. 



Knoxia umbellata, Banks. Herb. 



Found by Dr. Buchanan in the woods of Koorg, frv)m 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. — Leares opposite, short-petioled, lanceolate, 

 downy, entire; length from two to four inches high. — Connecting 

 membrane with several erect, filiform divisions ; when they accom- 

 pany the divisions of the inflorescence, they are more numerous, and 

 may be called an involucre. — Corymbs terminal, brachiate, 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 Hedyotis fruticosa, 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 cylindric, and shut with hairs ; finally the ca. sule is 

 there bipartible, opening from the base, with oblong brown seed, in
