0. Kalmiana. T. fy G.) Kalm's Pond Lily. 



"Floating Ivs. oblong, cordate, lobes approximate ; submersed Ivs. membra- 

 naceous, reniform-cordate, the lobes divaricate, margin waved, apex retuse ; " 

 stig. 8 12-rayed, somewhat crenate. A smaller species, with small yellow 

 flowers, growing in similar situations with the last, N. States. Dr. Robbins, 

 from whose MSS. the above is quoted, thinks it wholly distinct fromN. lutea, 

 Smith, or any other species. Petiole subterete; upper leaves 2 3' long 1J 2' 

 wide, lower leaves 34' diam. Jl. 



ORDER X. SARBACENIACEJE. WATER PITCHERS. 



Herbs aquatic, perennial in bogs, with fibrous roots. 



Lvs. radical, with a hollow, urn-shaped petiole and lamina articulated at summit. 



F Is. large, solitary, or several on scapes. 



Cal. Sepals 5, persistent, with a 3-leaved involucel at base. JEst. imbricate. 



Cw. Petals 5, unguiculate, hypogynous, concave. 



Sta. 00, hypogynous. Anth. oblong, adnate, introrse. 



Ova. 5-celled, placentas central. Sty. single. Stiff, dilated, peltate, 5-angled. 



FT. capsular, 5-celled, 5-valved, crowned with the broad persistent stigma. 



Sds. 00, minute. 



An order consisting of only 2 genera, (one inhabiting the bogs of N. America, the other in Guiana, ) 

 and 7 species. 



SARRACENIA. Tourn. 

 In memory of Dr. Sarrazen of Quebec, the discoverer of the genus. 



Calyx of 5 sepals, with 3 small bracts at base ; petals 5, deciduous; 

 stigma very large, peltate, persistent, covering the ovary and sta- 

 mens ; capsule 5-celled, 5-valved, many-seeded. 



S. PURPUREA. Side-saddle Flmver. 



Z/ys.(ascidia) radical, decumbent, inflated, contracted at the mouth,winged 

 on the inner side, ending in a broad-cordate, erect lamina. One of the most 

 curious of plants. Grows in wet meadows and about mud lakes, Lab. to Flor. 

 Leaves 6 9' long, rosulate, ever-green, composed of a hollow, pitcher-form 

 petiole (1) swelling in the middle, with a wing-like appendage extending the 

 whole length inside, from \ V wide, and extended on the outside of the mouth 

 into a lamina (!), covered above with reversed hairs. Their capacity when 

 of ordinary size is about a wine-glass, and they are generally full of water 

 with drowned insects. Scape 14 20' high, terete, smooth, supporting a single 

 large, purple, nodding flower, almost as curious in structure as the leaves. Jn. 

 0. hetcrophylla. Torr. (S. heterophylla. Eaton.} Scape rather shorter; 

 sep. yellowish-green; pet. yellow. Northampton, Ms. Mr. R. M. Wright! 

 Leaves scarcety different. 



ORDER XI. PAP AVERAGES. POPPYWORTS. 



Plants herbaceous, generally with a colored juice. 



Lvs. alternate, simple or divided, without stipules. 



Fls. solitary, on long peduncles, never blue. 



Cal Sepals 2, rarely 3, deciduous, imbricated in aestivation. 



Cor. Petals 4, rarely 5 or 6. hypogynous. 



Sta. often 00, but some multiple of 4, rarely polyadelphous. Anth. innate. 



Ova. solitary. Sty. short or 0. Stig. 2, or if more, stellate upon the flat apex of ovary. 



FT. either pod-shaped, with 2 parietal placentae, or capsular with several. 



Sds. 00, minute, Embryo minute, at the base of oily albumen. 



An order consisting of 18 genera and 130 species, more than two-thirds of which are natives of Europe. 

 The order is characterized by active narcotic properties, principally resident in the turbid juices. The 

 Beeds are commonly rich in fixed oil. Several of the species are highly ornamental in cultivation.
