Root thick, somewhat praemorse, with thick horizontal fibres' 

 Stem 8 — 10 inches high, thick, smooth. Leaves broad-oval of 

 obovate, about 4 inches long, and 2 and a half broad, clouded 

 with darker green, acute or slightly acuminate, 2-nerved. 

 Flowem closely sessile. Leaflets of the calyx ovate-oblong, 

 obtuse, persistent. Corolla dark purple, half as long again as 

 the calyx, rather obtuse. Filaments very short ; anthera 

 linear, nearly half an inch long, adnate to the filaments, and 

 opening on the inner side. Germen ovate, triangular ; stigmas 

 almost sessile, spreading, obtuse. Berry obtusely triangular, 

 dark purple. 

 Hab. On the sides of fertile hills, in shady and rocky grounds, 

 Pennsylvania to Carolina. ' Pursh. 



In my specimens, the petals are scarcely half as long again 

 as the calyx. It is probable that there are several species with 

 sessile flowers, confounded under the name of sessile. 1 have 

 specimens of a very distinct species discovered in Arkansa by 

 Mr. Js'uttall; and the yellow flowered variety mentioned 

 by Pursh and Muhlenberg is probably another. 



2. tryihrocarpnm Mich.: peduncle somewhat erect; 

 petals oval-lanceolate, acute, recurved, nearly as long again as 

 the narrow calyx ; leaves ovate, acuminate, rounded at the 

 base, abruptly contracted into a short petiole. M i ch. Fl.

 Root perennial. Stem about 8 inches high. Leaves broad-ovate, 

 much acuminate, somewhat cordate ; the base abruply con- 

 tracted into a short, but distinct petiole. Peduncle half as long 

 as the leaves, inclined to one side. Calyx about half the length 

 of the corolla ; leaflets lanceolate, acute. Corolla white, with 

 purplish veins towards the base; undulate on the margin. 

 Stigmas short, recurved. Berry oblong, scarlet. 

 Hab. In sphagnous swamps abounding with evergreens, espe- 

 cially on mountains. Deerfield, Massachusetts. Coo ley

 the cedar swamp, New-Durham, New-Jersey. Pennsylvania,

Among my specimens of Trillium, are two from Deer- 

 field, Massachusetts, in which there are three distinct, though 

 short styles, with the stigmas nearly erect ; in every other re= 

 spect they resemble T erythrocarfium.
