The pitcher trap evolved independently in three eudicot lineages and one monocot lineage, representing a case of convergent evolution. [10] 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 ...
Sarracenia trap insects using pitchers with nectar and slippery footing around the lip The anatomy of S. purpurea. Sarracenia (/ ˌ s ær ə ˈ s iː n i ə / or / ˌ s ær ə ˈ s ɛ n i ə /) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers.
The pitchers develop a dark red colour in high light levels but stay green in shadier conditions. The foliage is a basal arrangement that is closely arranged with outward facing adapted leaf blades. These leaves give the main form of the species a height around 20 cm. The 'pitcher' trap of the species is similar to other pitcher plants.
An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3]Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
The pitcher is a trap consisting of the main pitcher cup, covered by an operculum or lid. A reflexed ring of hardened tissue, the peristome, surrounds the entrance. N. rajah produces two distinct types of trap. "Lower" or "terrestrial" pitchers, the most common, are very large, richly coloured, and ovoid in shape.
The pitcher tube of this species is similar to that of Sarracenia flava, but has a wider pitcher mouth and neck and is usually somewhat shorter, reaching only 60 cm. (24 in). The uppermost part of the leaf is flared into a lid (the operculum), which prevents excess rain from entering the pitcher and diluting the digestive secretions within.
