CLASS XIII. ORDER I. 227 



ventral wing arched ; appendix broad heart shaped, 

 waved. 



The whole of this genus are plants of very singular structure. 

 The Sarracenia purpurea is the only one which endures our 

 climate. The leaves, which are all radical, are formed by a 

 large hollow tube, swelling in the middle, curved and diminish- 

 ing downward, till ii ends in a stem, contracted at the mouth, 

 furnished with a large, spreading, heart shaped appendage at 

 top, which is hairy within, the hairs pointing downwards; and 

 a broad, wavy wing extending the whole length on the inside. 

 The full grown leaves will contain a wine glass of water, and 

 are rarely found empty. The scape is long, smooth, and cylin- 

 drical, supporting a large, nodding flower. Exterior calyx of 

 three small leaves; interior of five ovate, obtuse leaves, shining, 

 and of a brownish purple. Petals five, panduriform, obtuse, re- 

 peatedly curved inward and outward, and finally inflected over 

 the stigma, brownish purple above, green below, deciduous. 

 Stamens numerous, with short filaments and large bilocular, 

 oblong, peltate, yellow anthers. Style short, cylindrical sup- 

 porting the broad, spreading stigma, divided, at its margin, into 

 five bifid lobes, alternating with the petals. Properly speaking, 

 this curious plant has five stigmas, which are projecting points 

 with moist tops situated under the notches of the lobes. —

 TiLiA Americana L. Lime Tree or Bass Wood. 



Leaves roundish heart shaped, abruptly acuminate, 

 sharply serrate, smooth; petals tnmcatcd at top; nut 

 ovate. Mich. f. 



A tree of the middle size, remarkable for the neatness of its 

 foliage, and the singularity of its flowering. The leaves are 

 large, roundish, heart-shaped at base, finely serrated. The foot- 

 stalk, supporting a bunch of flowers, proceeds from the centre of 

 an oblong, pale, floral leaf or bracte, as in the others of the genus. 

 Flowers greenish white, succeeded by small, hard, greyish cap- 

 sules. The wood of this tree is white, smooth, and soft. It is
