3 S. purpurea L, Side-saddle Flower. Ims. short, decumbent, inflated rnost 

 near the middle; lamina iroad'cordcUe. — Bogs throughout Can. and U.S. This 

 species is the most common, and on it the genus was founded. Ivs. 6 — 9' long, 

 rosulate, evergreen,, composed of a hollow, pitcher-form petiole, swelling in the 

 middle, with a wing-like appendage extending the whole length inside, from 

 J— 1' 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 ' generally, like the other species, they contain 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. 



l3. HETEKOPHTLLA Torr. Scapo rather shorter; sep. yellowish green; pet. 

 yellow.— Korthamplon, Mass. (R. M. "Wright). Lvs. scarcely different. ■ (S. 

 heterophylla Eaton.) 



4 S. Gronbvii. Tkumpet-Leap. I/vs. tall, straight, erect, tube gradiualhi. enlarged 

 to the open throat, wing narrowly linear, lamina sub-erect, roundish, mucronate, con- 

 tracted at base. — The largest species of the genus, in swampy pine woods, Va. to 

 Ela. and La. Lvs. often 3f in bight, and the scapes even taller ; the lamina as 

 broad as the open throat (2 — 3'). Fls. very large (when extended 4 — 5' 

 diam.) and of exactly the same structure in all the varieties. 



a. PLAVA. Ms. yellow ; foliage yellowish green, with or vrithout purplish veins 

 (S. flava L. S. Catesbsei Ell.). 



3. ALATA. Pis. yellow? large; lvs. 1 — 2f high, with the tube somewhat 

 ventricous above, throat contracted, wing conspicuous (J' broad). La. 

 (Hale). — A remarkable variety. 



y. EUEEA. Els. reddish purple, smaller than S. purpurea. Lvs. 1 — 2f high, 

 with purple veins (S. rubra Walt.) . 



il. Dbummondii. Els. purple, very large ; lvs. very tall (20 — 30'), remark- 

 ably mottled above with purple veins and white, diaphanous interstices. (S. 

 Drummondii Croom) Fla. (Chapman.) 



Order XII. PAP AVERAGES. Poppy-worts. 



3eris with alternate, exstipulate leaves, and generally a milky or colored juice. 

 .Rs. solitary, on long peduncles, never blue, hypogynous, regular, •/ or ^. jSfsp. 

 2, rarely 3, caducous, and petals 4, rarely 6, all imbricated. Sta. indefinite, but 

 some multiple of 4. Anthers 2-ceUed, innate. Ova. compound. Sty. short or 0. 

 Stig. 2, or if more, stellate upon the flat apex of ovary. JPr. either pod-shaped, 

 with 2 parietal placentae, or capsular, with several. Sds. Co, minute. Embryo 

 minute, at the base of oily albumen. (FigS: 229 — 231, 2'Z6.) 



An order consisting of 15 genera and ISO species, more tban two-thirds of which arc natives 

 of Europe. Tlie order is characterised by active narcotic properties, principally resident in the 

 turbid juice. Opium is the dried milky juice of Papaver somniferum. The seeds are com- 

 monly rich in fixed oil. Several of the species arc highly ornamental in cultivation.
