214 Class XIII. Order I. 



peltate, yellow anthers. Style short, cylindrical supporting the 

 broad, spreading stigma, divided, at its margin, into five bifid 

 lobes, alternating with the petals. Properly speaking this curi- 

 ous plant has five stigmas, which are projecting points with moist 

 tops situated under the notches of the lobes. Swamps and mea- 

 dows. June. Perennial. 



217. TILIA. 

 TILIA AMERICANA. L. Lime Tree or Bass Wood. 



Leaves roundish-heart shaped, abruptly acuminate, 

 sharply serrate, smooth ; petals truncated 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 footstalk 

 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 used 

 in the manufacture of certain kinds of furniture, and of the pan- 

 nels of carriages. The bark is fibrous, strong, and flexible, and 

 makes tolerable ropes. July. 



218. SANGUINARIA. 



SANGUINARIA CANADENSIS. L. Blood Root. 



Bigelow, Medical Botany, PI. vii. 



This is one of our earliest spring flowers. The flower and 

 leaf proceed from the end of a horizontal, fleshy, abrupt root, 

 fed by numerous radicles. This root makes offsets from its 

 sides, which separate as the old root decays, acquiring by this 

 separation the abrupt or premorse form. 



Externally the colour of the root is a brownish red. Inter- 

 nally it is pale, and when divided emits a bright orange coloured 

 juice from numerous points of its surface. The bud or hyber- 

 naculum, which terminates the root, is composed of successive 

 scales or sheathes, the last of which acquires a considerable size, 

 as the plant springs up. By dissecting this hybernaculum in the 

 summer or autumn, we may discover the embryo leaf and flower
