 simple, with the angles a little winged ; leaves sessile, oblong, 

 acute, with 6-7 prominent veins on each side ; stipulas trian- 

 gular, 3-4-toothed at the apex : teeth acute, middle one the 

 largest; heads of flowers axillary and terminal: lower ones on 

 short peduncles, the rest sessile ; lobes of calyx 4, lanceolate-li- 

 near ; lobes of corolla smoothish ; stamens exserted. If.S. Na- 

 tive of Brazil, where it was collected by Pohl. Corolla very like 

 that of B. Poaya when dry. Perhaps the same as Spermacoce

 herbaceous, simple, tetragonal ; leaves sessile, oblong-elliptic, 

 acute, obliquely 6-nerved on both sides of the mid-rib ; stipulas 

 cleft into many long bristles; whorles of flowers capitate, sessile, 

 few axillary, and a larger terminal one ; lobes of calyx 4, lanceo- 

 late-linear, acute, longer than the ovarium ; corolla smoothish ; 

 anthers exserted. If.. S. Native of Brazil, in elevated pas- 

 tures, in the mine provinces frequent. Spermacoce Poaya, var. 

 a, St. Hil. pi. us. bras. no. 12. t. 12. Corolla blue, with the 

 lobes rather hairy above. The roots are white, and are substi- 

 tuted with success in place of Ipecacuanha. The leaves are at 

 first sweet, but afterwards acid, and a decoction of them is used 

 in the cure of cholic.

 I/ . S. Native of Brazil, where it was collected by Pohl. Sper- 

 macoce latifolia, Pohl, in litt. but not of Aubl. Bristles of sti- 

 pulas 6 lines long. Very nearly allied to B. Poaya, but differs 

 in being hispid. Corolla unknown.

63 B.? GYMNOCE'PHALA (D. C. prod. 4. p. 549.) stem branched,

 lated ; leaves ovate, acute, attenuated at the base, glabrous, ob- 

 liquely nerved ; bristles of stipulas 7-9, longer than the sheath ; 

 whorles of flowers nearly globose, many axillary, and one ter- 

 minal, which is naked from the abortion of the floral leaves ; 

 teeth of calyx 2-3, conically subulate. Native of Brazil.
