The two exterior sepals mucli narrower and bract-like. Petals 3, inconspicuous, lanceolate, 

 somewhat persistent. Stamens 3 - 12. Stigmas 3, nearly sessile, somewhat united, fim- 

 briate-laciniate, depressed. Capsule 3-valved, incompletely 3-celled, or one-celled by the 

 obliteration of the imperfect dissepiments : placentas (internal valves, Linn.) ovate or 

 roundish, nearly as broad as the valves, membranaceous or somewhat crustaceous, fixed 

 to the dissepiments by the middle of the posterior face, about two-seeded. Seeds borne 

 on the posterior face of the placentae near the base, one on each side of the dissepiment, 

 about the middle of the valves. Embryo nearly straight. — Perennial herbs, often sufTru- 

 ticose at the base, much branched, with numerous very small racemed or somewhat pani- 

 culate flowers : petals brownish-purple. Leaves without stipules, entire, alternate, opposite 

 or verticillate (often on the same specimen), sessile or slightly petioled, minutely puncticulate. 



^ Lechea proper, Spach. Placenta: membranaceo-cruslaceous, fragile, separating from the very 

 thin dissepiments ; the margins revolute, and enveloping the seeds.

 Stolons numerous, 3-6 inches long, bearing numerous crowded leaves which are often 

 verticillate or fascicled and only 2-4 lines long. Cauline leaves alternate, opposite or im- 

 perfectly verticillate and more or less crowded, villous with spreading whitish hairs, especial]}'
