SARRACENIACEAE PITCHER-PLANT FAMILY

Barry A. Rice

Perennial herb, generally from slender rhizome, short caudex, or stolon; carnivorous; roots poorly developed. Leaf: in basal rosette, prostrate to erect, each forming a tubular pitcher with fluid that digests captured prey by enzymes, bacteria, or other organisms, with stiff, reflexed hairs within. Inflorescence: scapose, flower generally 1. Flower: bisexual, radial, nodding; sepals 5 [4–6], generally free; petals 5 [0]; stamens many; pistil 1, ovary superior, chambers generally 5, incomplete above or not, placentas generally axile, style 1, 5-lobed, umbrella-like or not, stigma terminal or under tips of style lobes. Fruit: capsule, loculicidal; valves generally 5. Seed: many, flattened-ovoid, smooth, or club-like, papillate [winged].
3 genera, 24 species: northern California, Oregon, British Columbia, eastern North America, northern South America, especially acidic bogs, streamsides, moist areas; often planted outside native ranges by horticulturists but generally not invasive.

Leaf: pitcher top generally with vertical or overhanging lid [top dome-like, without glassy-transparent windows, only in Sarracenia psittacina and its hybrids], opening generally upward, tube with digestive fluids within. Flower: sepals, petals 5; ovary chambers 5, style tip umbrella-like, peltate.
11 species: eastern United States, eastern Canada to British Columbia. (Michel S. Sarrazin, Quebec physician, naturalist, 1659–1735) Many species, hybrids (traits intermediate) planted in northern California (Mendocino, Del Norte cos.; expected elsewhere), proliferating slowly if at all.
