 inches long. Scape a foot or more high, 8-20-flowered. Flowers larger than 

 in the other species. Cells of the anther linear-oblong, nearly distinct, at 

 length separable from the rhombic-lanceolate connectivum. — Tlie flowers in 

 all the specimens from Florida are nearly twice the size of liie northern 

 plant ; bi-ing about an inch in diameter when fully expanded.

Stamens 10-15: anthers innate. Style 1, thick: stigmas 5, connivent, 

 fimbriately many-cleft. Capsule membranaceous, indehiscent, but tearing 

 open irregularly (5-valved, DC), 1-celled. Seeds numerous (20-30), partly 

 immersed in the scrobiculate cellular placenta which fills the base of the cap- 

 sule. — A glabrous perennial (yellowish-green) herb. Flowers umbellate at 

 the extremity of a slender scape. Leaves (not circinate in vernation) radi- 

 cal, rosulate and spreading ; petiole winged and foliaceous, terminating in an 

 articulated circular spinulose-ciliate lamina, which is very sensitive, suddenly 

 closing when the upper surface is touched. — Vemis^s Fly-trap. 



Arnott places Dionrea in his suborder ParnassicEe; but we prefer to retain it in 

 Droseracese proper, with which it agrees more nearly in habii, and from wliicli it 

 differs in no important character except in tlie vernation, and in the placenta which 

 fills the bottom of the ovary; the style, moreover, is just such an one as would he 

 produced liy the cohesion of the rnultifid styles of" some species of Drosera nearly 

 to the summit. On tlie oilier hand, it differs from Parnassia in most of the peculiar 

 characters of that o^enus, viz.: the peri^ynous stamens, a portion of which are abor- 

 tive or transformed, tlie sessile stigmas opposite the placenlte, and the albuminous 

 seeds.
