is vaulted, and formed into a sac, which (in the full-grown leaf) is 

 about the size of a hen's egg, on the other side of which is an oval 

 orifice, about an inch in diameter, opening into the cavity of the 

 pitcher. The areolae of the sac, and also of the back of the tube on 

 the upper part, are discolored (of a dull orange color in the dried 

 specimens), as in Sarracenia variolaris and 8. Drummonclii. Along 

 the inside of the petiole is a narrow wing, which is single, except at 

 the base, where it separates into two plates that clasp the scape and 

 the base of the superior leaves. The lamina is narrow at the base, 

 and deeply divided into two somewhat unequal widely spreading lobes, 

 which are oblong-lanceolate, rather acute, bent downwards and often 

 also backwards ; the inner (or properly upper) surface very minutely 

 pubescent. The pitcher, inside the hood, is retrorsely hirsute with 

 short conical hairs; from thence downwards it is glabrous, except 

 towards the bottom, where it is lined with slender hairs, also pointing 

 downward: at the bottom the remains of insects were found. Neither 

 these hairs nor those of the lamina appear to be of a secreting char- 

 acter. They are almost precisely similar to those of the leaves of 

 Sarracenia.* The scape is from one to four feet long, flexuous, angu- 

 lar, glabrous, and furnished with sessile clasping straw-colored scales. 

 These scales are foliaceous and alternate, the lower ones distant and 

 lanceolate, the upper more and more approximated and broader, while 

 those near the flower are oblong-ovate and imbricate. They are 

 marked with longitudinal veins, which are forked toward the ex- 

 tremity. The upper surface is paler, and under a lens shows minute 

 conical papillae. The flower, when fully expanded, is nearly two 

 inches in diameter. The calyx consists of five oblong rather acute 

 sepals, which are of a pale straw color, and are quincuncially imbri- 

 cated. There are no calyculate bracts at their base. The corolla is 

 5-petalled, about the length of the calyx, and its aestivation is like- 

 wise quincuncial. The petals are oblong, pale purple, marked with 

 deeper reticulated veins, and are apparently not connivent over the 

 pistil. They are furnished with a small ovate lamina, and very broad 

 obovate claw, which is two or three times longer than the lamina. 

 Stamens 12-15, hypogynous, in a single series, and partly concealed 

 by the dilated summit of the ovary : filaments short and rather stout : 

 anthers oblong, with the cells very unequal, and opening longitudi-
