1. S. purpùrea, L. (SIDE-SADDLE FLOWER. PITCHER-PLANT. HUNTSMAN'S CUP.) _Leaves pitcher-shaped_, ascending, curved, broadly winged; the hood erect, open, round heart-shaped; _flower deep purple_; the fiddle-shaped petals arched over the greenish-yellow style.--Varies rarely with greenish-yellow flowers, and without purple veins in the foliage.--Peat-bogs; common from N. Eng. to Minn., N. E. Iowa, and southward east of the Alleghanies. June.--The curious leaves are usually half filled with water and drowned insects. The inner face of the hood is clothed with stiff bristles pointing downward. Flower globose, nodding on a scape a foot high; it is difficult to fancy any resemblance between its shape and a side-saddle, but it is not very unlike a pillion. 2. S. flàva, L.
