PITCHER PLANT FAMILY 291 
often secondarily divided. Plant hairy, Calyx and corolla each 6-parted, 
irregularly divided. Petals quite small, greenish-yellow. Introduced. 
In waste places, in southern part of our area. 
3. R. alba, L. Waite Curt-Leavep Micnonerre. Calyx and corolla 
of 5 divisions each, petals with about 4 teeth, white. Plant smooth, 1 to 
3 ft. high. Introduced in widely separated localities. 
Order V-Z=SARRACENIALES. Order of Pitcher Plants 
Insectivorous plants which secrete a viscid substance attractive 
to insects and which aids in their capture. The leaves are all 
basal and from the midst of this basal cluster of leaves arises a 
slender flower stem bearing one or several nodding flowers. There 
are 4 or 5 calyx. divisions arising below the ovary and 5 petals. 
Stamens numerous. Fruit a capsule 3- to 5-celled. 
Famity I.— SARRACENIACEAE. Pircurer Puanr Faminy 
Characters those of the order, but all leaves are hollow, pitcher- 
formed or trumpet-shaped. 
1. SARRACENIA, L. 
Perennial herbs growing in bogs. Leaves all at the base, hollow or 
pitcher-shaped, with a wing at one side. Flowers solitary on a tall scape, 
nodding; calyx of 5 sepals with 3 small bracts at base. Petals 5. The 
extremity of the pistil spreads out as a broad shield-like plate covering 
the ovary. Its 5 rays terminate below and constitute as many stigmas. 
Fruit a capsule of 5 cells. 
S. purpurea, L. (Fig. 5, pl. 58.) PrtcHerR PLantT. SimpE-sADDLE 
FLower. This, the only species in our region, is one of the most curious 
of our plants. It is found in peat bogs where it often grows in con- 
siderable beds. The hollow leaves entice insects within their recesses 
where, owing to the stiff hairs pointing downward and the viscid se- 
cretions, may of the prisoners die. It is supposed that the juice from the 
insects contribute toward the nutrition of the plant. The flower stem 
is from 15 to 20 in. high. Flowers purple and yellow. Blooms in June. 
Famity II.—DROSERACEAE. Sunpew Famity 
Delicate herbs growing in mossy bogs. Leaves mostly in a 
basal whorl covered, especially at the edges, with glandular hairs 
and in the center with a viscid exudation. Flowers on a slender 
scape, nodding, with 4 or 5 sepals and 5 petals. Stamens 4 to 
numerous; pistils 3 to 5; ovary globose with the calyx attached 
at. base.
