SARRACENIACE^E. (PITCHER-PLANT FAMILY.) 57 



surpassing the disk-like 8 - 24-rayed sessile stigma. Fruit ovoid, naked, usually 

 ripening above water. Aril none. Leaves with a deep sinus at the base. 

 Flowers yellow or sometimes tinged with purple, produced all summer. 

 (Nov<ap of Dioscorides, from the Egyptian name.) Our various forms seem 

 to include only two species. 



1. N. advena, Ait. (COMMON Y.) Sepals 6, unequal; petals shorter 

 than the stamens and resembling them, thick and fleshy, truncate; stigma 12- 

 24-rayed ; ovary and fruit not contracted into a narrow neck under the stigma ; 

 thin submersed leaves seldom appearing ; floating or emersed and erect leaves 

 thick, varying from roundish to ovate or almost oblong in outline, the sinus 

 open, or (var. VARIEGA.TUM, Engelm., flower often partly purplish) closed or 

 narrow. Very common, in still or stagnant water. 



2. N". Itlteum, Smith. (SMALLER Y.) Sepals 5, nearly equal; petals 

 longer and dilated upwards; stigma 12-16-rayed; fruit globular, with a short 

 narrow neck; earlier and submersed leaves very thin and delicate, roundish, 

 the floating ones oval and usually with a narrow or closed sinus. The only 

 specimen seen like the European (expanded flower fully 2' across) is from 

 " Manayunk, 7 miles from Philadelphia," in herb. Collins, now Durand. (Eu.) 



Var. piimilum. (SMALL Y.) Flower ' - 1' across when outspread ; 

 leaves l'-5' long. (N. pumilum, Hoppe. N. Kalmiana, Pursh.) Ponds, N. 

 England to Penn. and northward. (Eu.) 



N. POLYSEPALUM, Engelm., with very large flowers and numerous sepals, 

 occurs far west 



K". SAGITTIF6LIA, Pursh, of N. Carolina and southward, has narrow and 

 long leaves. Both perhaps run into No. 1. 



, ORDER 7. SARRACENIACE^E. (PITCHER-PLANTS.) 



Polyandrous and hypogynous bog-plants, with hollow pitcher-form or 

 trumpet-shaped leaves, comprising one plant in the mountains of Gui- 

 ana, another (Darlingtonia, Torr.) in California, and the following genus 

 in the Atlantic United States. 



1. SARRACENIA, Tourn. SIDE-SADDLE FLOWER. 



Sepals 5, with 3 bractlets at the -base, colored, persistent. Petals 5, oblong 

 or obovate, incurved, deciduous. Stamens numerous, hypogynous. Ovary 

 compound, 5-celled, globose, crowned with a short style, which is expanded at 

 the summit into a very broad and petal-like, 5-angled, 5-rayed, umbrella-shaped 

 body ; the 5 delicate rays terminating under the angles in as many little hooked 

 stigmas. Capsule with a granular surface, 5-celled, with many-seeded placentae 

 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.)
