222 ORDER 12. PAPAVERACE./E. 



3 S. purptirea L. SIDE-SADDLE FLOWER. Los. short, decumbent, inflated most 

 near the middle ; lamina broad cordate. Bogs throughout Can. and U.S. This 

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

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

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

 \ 1' wide, and extended ou 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. 



f3. HETEROPHYLLA Torr. Scape rather shorter ; sep. yellowish green ; pet 

 yellow. Northampton, Mass. (R. M. "Wright). Lvs. scarcely different. (S. 

 heterophylla Eaton.) 



4 S. Gronovii. TRUMPET-LEAF. Los. tall, straight, erect, tube gradually enlarged 

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

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

 Fla. 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 tho same structure in all the varieties. 



a. FLAVA. Fls. yellow ; foliage yellowish green, with or without purplish veins 

 (S. flava L. S. Catesbsei Eli). 



B. ALATA. Fls. yellow? large; Ivs. 1 2f high, with the tube somewhat 

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

 (Hale). 'Intermediate between species 3 and 4 ; perhaps distinct. 



y. RUBRA. Fls. reddish purple, smaller than S. purpurea. Lvs. 1 2f high, 

 with purple veins (S. rubra Walt.). 



6. DRUMMONDII. Fls. purple, very large; Ivs. very tall (20 30), remark- 

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

 Drummondii Groom) Fla. (Chapman.) 



ORDER XII. PAP AVERAGES. POPPY-WORTS. 



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

 Fls. solitary, on long peduncles, never blue, hypogynous, regular, ^/ or j/. Sep. 

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

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

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

 with 2 parietal placentas, or capsular, with several. Sds. 00, minute. Embryo 

 minute, at the base of oily albumen. (Figs. 229231, 276.) 



An order consisting of 15 genera and 130 species, more than two-thirds of which are natives 

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

 turbid juice. Opium is th dried milky juice of Papaver soniniferum. The seeds are com- 

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

1. SANGUINARIA, L. BLOOD-ROOT. (Latin sanguis, blood ; all its 

 parts abound in a red juice.) Sepals 2, caducous ; petals 8 12, in 2 

 or 3 rows, the outer longer. Stamens about 24 ; stigma sessile, 1
