The Side-saddle Flower (Sarrecenia purpuria, Fig. CC,) a North Americanplant, found growing in peat hogs, hears pitchers which are evidently formed bythe very deep channelling of the petiole, and the union of the involute edges of itswinged margin, so as to form a complete vase, with a broad expansion at the tip,which may he regarded as the true leaf.
