Description
This emerging Pitcher Plant was photographed in a fen in the Bruce Peninsula, Ontario.
Sarracenia purpurea, commonly known as the purple pitcher plant, northern pitcher plant, or side-saddle flower, is a carnivorous plant in the family Sarraceniaceae. Its range includes almost the entire eastern seaboard of the United States, the Great Lakes, and south eastern Canada, making it the most common and broadly distributed pitcher plant, as well as the only member of the genus that inhabits cold temperate climates. The species is the floral emblem of the Canadian province of Newfoundland and Labrador. The species was introduced into bogs in parts of Ireland, where it has proliferated
Pitcher plants are carnivorous plants whose prey-trapping mechanism features a deep cavity filled with liquid known as a pitfall trap. It is widely assumed pitfall traps evolved by epiascidiation (infolding of the leaf with the axadial or upper surface becoming the inside of the pitcher), with selection pressure favouring more deeply cupped leaves over evolutionary time. The pitcher trap evolved independently in three eudicot lineages and one monocot lineage, representing a case of convergent evolution. Some pitcher plant families (such as Nepenthaceae) are placed within clades consisting mostly of flypaper traps, indicating that some pitchers may have evolved from the common ancestors of today's flypaper traps by loss of mucilage.
