in the axis, 5-valvecl. Seeds anatropous, with a small embryo at the base of 

 fleshy albumen. — Perennials, yellowish-green and purplish; the hollow leaves 

 all radical, with a wing on one side, and a rounded arching hood at the apex. 

 Scape naked, 1-flowercd: flower nodding. (Named by Toumefort in honor 

 of Dr. Sairazin of Quebec, who first sent our Northern species, and a botanical 

 account of it, to Europe.) 



1. S. purpurea, L. (Side-saddle Flowee. Pitcher-Plant. 

 Huntsman's Cup.) Leaves pitcher-shaped, ascending, cun'ed, 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. (S. heteroph3'lla, 

 Eaton.) — Peat-bogs ; common from N. England to Wisconsin, and southward 

 east of the Alleghanies. June. — The curious loaves are usually half filled 

 with water and drowned insects : the inner face of the hood is clothed with stiff 

 bristles pointing downwai'd. Elower 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 veiy unlike a pillion. 



2. S. flava, L. (Trumpets.) Leaves long (l°-3°) and trumpet-shaped, 

 erect, with an open mouth, the erect hood rounded, nan-ow at the base ; wing 

 almost none; flower yellow, the petals becoming long and drooping. — Bogs,
