24 PAPAVEKACE^E. (POPPY FAMILY.) 



in the axis, 5-valved. Seeds anatropous, with a small embryo at the base of 

 fleshy albumen. Perennials, yellowish-green and purplish; the hollow leaves 

 all radical, with a wing on one side, and a rounded arching hood at the apex. 

 Scape naked, 1-flowered : flower nodding. (Named by Tournefort in honor 

 of Dr. Sarrazin of Quebec, who first sent our Northern species, and a botanical 

 account of it, to Europe.) 



1. S. purpurea, L. (SIDE-SADDLE FLOWER. PITCHER-PLANT. 



HUNTSMAN'S CUP.) Leaves pitcher-shaped, ascending, curved, broadly winged, 

 the hood erect, open, round heart-shaped ; flower deep purple ; the fiddle-shaped 

 petals arched over the (greenish-yellow) style. Varies rarely with greenish- 

 yellow flowers, and without purple veins in the foliage. (S. heterophylla, 

 Eaton.) Peat-bogs ; common from N. England to Wisconsin, and southward 

 east of the Alleghanies. June. The curious leaves are usually half filled 

 with water and drowned insects : the inner face of the hood is clothed with stiff 

 bristles pointing downward. Flower globose, nodding on a scape a foot high : 

 it is difficult to fancy any resemblance between its shape and a side-saddle, but 

 it is not very unlike a pillion. 



2. S. flava, L. (TRUMPETS.) Leaves long (l-3) and trumpet-shaped, 

 erect, with an open mouth, the erect hood rounded, narrow at the base ; wing 

 almost none ; flower yellow, the petals becoming long and -drooping. Bogs, 

 Virginia and southward. April. 



ORDER 10. PAP AVERAGES. (POPPY FAMILY.) 



.Herbs with milky or colored juice, regular flowers with the parts in tivos or 

 fours, fugacious sepals, polyandrous, hypogynous, the ovary 1-celled with 2 or 

 more parietal placentae. Sepals 2, sometimes 3, falling when the flower 

 expands. Petals 4-12, spreading, imbricated in the bud, early deciduous. 

 Stamens 16 -many, distinct. Fruit a dry 1-celled pod (in the Poppy im- 

 perfectly many-celled, in Glaucium 2-celled). Seeds numerous, anatro- 

 pous, often crested, with a minute embryo at the base of fleshy and oily 

 albumen. Leaves alternate, without stipules. Peduncles mostly 1-flow- 

 ered. Juice narcotic or acrid.
