24 PAPAVEHACE^E. (POPPY FAMILY.) 



in the axis, 5-valvcd. 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 Tonmefoit in honor 

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

 account of it, to Europe.) 



1. S. purpiircn, 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 greemsh- 

 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 Alleghanics. 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. flitva, 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. (PorpY FAMILY.) 



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

 fours, fugacious sepals, polyandrous, hypooynous, the ovary I -celled with 2 or 

 more parietal placentce. Sepals 2, somef'mes 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-

 ered. Juice narcotic or acrid.
