 mag. t. 1243. 



Leaves always floating, 3-6 inches long (in the var. Kalmiana usually much smaller, 

 sometimes scarcely more than an inch long). Flower an inch and a half (the var. scarcely 

 an inch) in diameter. 



In ponds and slow-flowing waters : not rare in the interior of the Slate ; but seldom found 

 near the seacoast. Fl. June. 



The small-leaved variclv has been considered as a distinct species by some botanists ; but 

 it often passes into the common form.

Sepals commonly six, the outer ones smaller ; stigma slightly umbilicate, 1 2 - 25-rayed, 

 the margin repand or crenate ; leaves cordate, with the lobes diverging ; petioles semiterete. —

Rhizoma rooting in the mud at the bottom of the water, 2-4 inches in diameter and 

 several feet long, marked with the scars of former petioles. Leaves erect in shallow water, 

 floating on the surface when the water is deep, 6-10 inches long and 4-7 inches wide, 

 somewhat coriaceous ; petioles and peduncles varying in length according to the depth of the 

 water, stout. Flowers about two inches in diameter. Sepals roundish, concave, roughish : 

 the lluree exterior green, mixed with some yellow ; the three interior larger, yellow tinged with 

 green at the base. Petals 10 - 14, oblong, cuneate, truncate, fleshy, not half the length of 

 the sepals ; the inner ones gradually passing into stamens. Stamens 100 or more, at first 

 closely applied to the ovary, at length spreading. Ovary oblong ; the stigma large and sessile ; 

 the upper surface marked with 12 - 25 (usually from 12- 16) elevated radiating lines, which 

 are the true stigmas of the several carpels. 



Ponds and slow-flowing streams ; often where the water is brackish : common throughout 

 the State. Fl. Early in May - September. Fr. August - September. It is not easy at all times 

 to distino-uish this (especially the var. Kalmiana) from the preceding species. The flowers 

 sometimes occur with five sepals, and the stigma in the latter is often a little crenate. The 

 rhizoma is bitter and astringent, turning quickly black when cut with a steel knife. It is 

 sometimes used in domestic practice as a tonic, and, in a bruised form, as a poultice.
