3 S. purpurea L. Side-saddle Flower. Lvs. short, decumbent, inflated most 

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

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

 tracted at base. — The largest species of the genu-, in swampy pino woods, Va. to 

 Fla. and La. Lvs. often 3f in hight, and the scapes even taller ; the lamina aa 

 broad as tho open throat (2 — 3). FIs. very largo (when extended 4 — 5' 

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



a. flava. FIs. yellow ; foliage yellowish green, with or without purplish veins 

 (S. flava L. S. Catesbaei Ell.). 



B. alata. FIs. yellow? large; lvs. 1 — 2f high, with tho tube somewhat

Ordefv XII. PAPAVERACEyE. Poppy-worts. 



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

 Fls. solitary, on long peduncles, never blue, hypogynous, regular, *J or (/. 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. Sly. short or 0. 

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

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

 minute, at the base of oily albumen. (Figs. 229 — 231, 27G.) 



An order consisting of 15 genera ami 1.00 species, more than two-thirds of which fire natives 

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

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

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