Fam. 66. Sarraceniaceae Dum. Pitcher-plant Family 



Perennial rhizomatous and insectivorous plants with clustered tubiform leaves 

 and solitary nodding flowers borne on a long naked erect scape; leaves rigidly 

 erect, trumpet-shaped and partially filled with liquid, with a ridge on the adaxial 

 side and terminated by an expanded hood; flowers regular, bisexual; sepals 5, with 

 3 appressed persistent bracts; petals 5, pendent, deciduous; stamens numerous; 

 anthers 2-celled, dehiscing longitudinally; style simple below, expanded above 

 into a large persistent 5-lobed umbrellalike structure, with a small stigma under 

 each of the notched lobes; ovary 5-celled; fruit 5-valved; seeds keeled or winged 

 on one side. 



A small family of three genera comprising about 15 species. 



1. Sarracenia L. Pitcher-plant. Trumpet 



Characters of the family. A genus of 8 species, all of which are confined to 

 the United States with the exception of 5. purpurea L. which extends into Canada. 



1. Sarracenia alata Wood. Yellow trumpets. Frontispiece. 



Leaves yellow-green, trumpet-shaped, dilated upward, to 7 dm. long; hood ovate 

 to suborbicular, with inconspicuous reddish veins, 8 cm. long; scape about as 

 long as the leaves; sepals broadly ovate to rhombic-ovate, bluntly obtuse at apex, 

 curved, 4-5 cm. long, to 4 cm. wide; petals greenish-yellow, drooping, panduri- 

 form, 5-6 cm. long, to 4 cm. wide near the broadly rounded apex; style to 8 cm, 

 wide, convex; capsule muricate; seeds tuberculate. S. Sledgei Macfarl. 



In wet acid bogs on slopes and flats in pinelands in e. and s.e. Tex., Mar.-Apr.; 

 on the Gulf Coastal Plain from s. Ala. to e. Tex. 



An insect attractant is exuded near the mouth of the tubular leaf. After 

 entering the tube the retrorse bristly hairs lining its inner surface prevents the 

 insect from leaving the ingenious trap. It soon falls into fluid at the bottom of 

 the funnel and is then digested by the plant. 



Fam. 67. Droseraceae Salisb. Sundew Family 



Perennial or biennial (rarely annual) insectivorous herbs growing in wet or 

 damp soil; leaves circinate in bud, expanding into a rosette or tuft at base of 

 scape or rarely scattered in submersed plants, with or without prominent stipules, 

 red or green, adorned with gland-tipped hairs that exude drops of a clear glitter- 

 ing glutinous fluid; scape with a simple or branched few-flowered secund inflores- 

 cence that nods at the undeveloped apex; flowers regular, shortly pedicellate, 

 opening only in sunlight, hypogynous, usually 5-merous, soon withering but 

 persistent; calyx imbricated; petals convolute; stamens 5, opposite the sepals, the 

 anthers fixed by the middle; style 3 or 5, bipartite to base; capsule 3- to 5-valved, 

 with as many parietal placentas as valves; seeds numerous. 



About 4 genera of more than 125 species of world-wide distribution. 



1. Drosera L. Sundew 



Characters same as those of the family. More than 100 species primarily in the 

 Southern Hemisphere.
