Caudex, when the plant grows in water, sometimes 2-4 inches long. Leaves 1 - 1^ inch 

 long, the lamina 2-3 lines wide, with long fringed stipules at the base. Scapes 3-6 inches 

 high, usually curved to one side at the base, and then ascending, 5 - 9-flowered. Flowers 

 twice as large as in the preceding species. Sepals oblong, obtuse. Capsule ovoid-oblong. 



Sphagnous and sandy swamps. July - August. More rare than the preceding species.

Leaves filiform and very long, nearly erect, glandularly hairy, naked at the lower extremity, 

 the stipules at the base densely woollv ; scape longer than the leaves, many-flowered ; petals 

 (purple) obovate, erosely denticulate, much longer than the glandular calyx ; styles 2-parted 

 to the base, the segments filiform and slightly thickened upward ; seeds acute at each end, 

 minutely punctate, the testa not arilliform. — Raf. in med. rep. 2. p. 360, and in Desv.jour.

Leaves 6-10 inches long, about the thickness of a common packthread. Scapes (often 

 several from one root) 8-12 inches high, smooth, usually 8 - 12-flowered, rarely forked at 

 the base. Flowers, when fully expanded, half an inch in diameter, bright purple. Stamens 5 ; 

 anther-cells large, oblong, distinct, at length separating from the rhombic-lanceolate connec- 

 tivum ; the pollen-grains connected by fijie cobweb-like threads. Capsule shorter than the 

 calyx. Seeds blackish. 



Sandy wet places, a few miles east of East-Hampton, Suffolk countj', Long Island. 

 August - September. A singular and handsome plant ; first discovered by the late Mr. Rafi- 

 nesque, and described by him as early as the year 1808. According to Bigclow, the flowers 

 have ten stamens, but there were only five in all the specimens that I examined.
