GILLENIA. 



Calyx tubular, campanulate, contracted and 5-cleft at the 

 edge. Petals 5, ligulate, rather unequal, inserted in the apex 

 of the tube. Stamens 10-20, very short, enclosed in the tube. 

 Carpels 5, almost united into a 5-celled capsule ; style filiform, 

 erect, capitate. Seeds 2 in each cell.

Stems a foot or two in height, several from the same root, erect, 

 slender, flexuose, smooth, reddish-brown, and branched. Leaves 

 alternate, trifoliate, subsessile, furnished with small lanceolate, slightly 

 toothed stipules at the base ; leaflets lanceolate, acuminate, sharply 

 and unequally toothed, the upper ones often single. Flowers few in 

 number, scattered, terminal, nodding, forming a sort of panicle, with 

 long peduncles, occasionally furnished with minute lanceolate bractes. 

 Calyx subcampanulate, or tubular, with the lower half narrowest, the 

 border divided into 5 reflexed acute teeth. Petals 5, the 2 upper ones 

 separated from the 3 lower, white, with a reddish tinge on the edge, 

 lanceolate, unguiculate, contracted, and approximated at base. Sta- 

 mens about 20 in a double series within the calyx. Capsules 5, 

 diverging, oblong, acuminate, gibbous without, sharp edged within, 

 2-valyed, 1 -celled, 1 or 2 seeded; seeds oblong, corresponding in shape 

 to the capsule. The root is emetic, and possesses properties analo- 

 gous to those of Ipecacuanha. It requires, however, a larger dose, and 

 is considered uncertain in its operation.

SPIR.EA. 



Calyx inferior, nearly flat at the base, with 5 acute segments. 

 Petals 5, roundish or oblong, attached by their claws to the rim of 

 the calyx. Filaments more than 20, from the rim of the calyx, capil- 

 lary ; nearly as long as the corolla. Carpels 5, or more, superior, 

 ovate or oblong, compressed, each terminating in a short stout style. 

 Stigmas spreading, obtuse. Capsules as many as the carpels, 

 oblong, pointed, more or less compressed, each of 2 rather mem- 

 branous valves, and 1 cell. Seeds few, small, oblong, pendulous 

 from the outer margin of each valve.

Root fibrous, without knobs. Stems 3 or 4 feet high, leafy, branched, 

 furrowed, angular, smooth. Leaves of a few large, pointed, unequally
