the uppermost oblons^ or oblong-lanceolate, sessile, scabrous on the margin ; 

 upper ones usually much narrower, acute. Stipules nearly half us lung as 

 the leaves. Flowers 2 lines long: peduncles slender, much shorter ihaii ihe 

 leaves, without bracteoles, articulated above the middle. Sepals nearly equal, 

 strongly carinate. Lower petal contracted into a claw in the middle, dilated 

 again and somewhat gibbous at the base; limb emarginate, strongly veined; 

 lateral petals incurved, oblong; superior ones nmch the smallest. Filaments 

 contracted at the base into a short but distinct (-law ; upper portion ovate and 

 somewhat acute; the lowest two with a small subulate appendage pointing 

 upward. Ovary triangular : style slender: stigma small, not rostrate. Cap- 

 sule 3-sided, glabrous, about 6-seedcd. Seeds ovate-globose, glabrous, light 

 brown.

On the Red River, Arkansas, Dr. James f — Leaves an inch or more in 

 length, scarcely more than a line long, pale green, scabrous on the margin. 

 Stipules one-third the length of the leaves. Capsules glabrous. — Of this 

 plant we have but a single imperfect specimen, which was collected by Dr. 

 James in Long's 1st Expedition. It may prove to be a variety of L stipula- 

 ceum, but it differs considerably from that species.

Sepals 5, persistent, equal, sometimes united at the base, imbricated 

 in aestivation. Petals 5, alternate with the sepals, nearly or quite hy- 

 pogynous, marcescent. Stamens distinct, marcescent, usually as 

 many as the petals and alternate with them, rarely 2-3 times as many : 

 filaments capillary or flattened : anthers extrorse or innate ; cells 

 distinct, or somewhat connivcnt above, opening longitudinally, or rare- 

 ly by a terminal pore. Ovary composed of 2-5 united carpels, l-cel- 

 led : placentae parietal, or filling the base of the cell : styles 2-5, usu- 

 ally distinct or united at the base merely, each 2-parted or multifid 

 and pencil-shaped ; sometimes all united into one. Capsule 2-5-valv. 

 ed, loculicidal, with the valves placentiferous in the middle, or indehis- 

 cent with the placenta at the base, many- (rarely few-) seeded. Seeds 

 anatropous : testa sometimes arilliform. Embryo short, at the base 

 of cartilaginous or fleshy albumen. — Herbs, or rarely suflrutescent 

 plants (growing in swamps or wet places). Leaves alternate or 

 crowded, entire, commonly furnished with glandular hairs, with a cir- 

 cinate vernation (except Dionsea) : stipules none, or in the form of a 

 tuft or fringe of scarious hairs at the base of the petioles.

Stamens 5. Styles 3-5, 2-parted ; the divisions somewhat thickened 

 toward the apex, or multifid. Capsule subglobose or ovoid, usually 3-valved 

 at the top : valves placentiferous to the summit. Seeds verv numerous, in
