24 papaveraceje. (poppy family.) 



in the axis, 5-valved. Seeds anatropous, with a small embiyo 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 Toumefort in honor 

 of Dr. Sairazin 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. (Illinois, Dr. Vasey.) 



2. S. flaLVU, 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. PAPAVERACE^E. (Poppy Family.) 



Herbs with milky or colored juice, regular flowers icith the parts in twos or

 more parietal placenta*. — 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.
