Sarracenia purpurea
Sarracenia purpurea
The Red pitcher plant ( Sarracenia purpurea) is a carnivorous plant from the family of Pitcher plants ( Sarraceniaceae ), which occurs from Florida to Canada anywhere in North America.
Description
The Red Pitcher Plant applicable in phylogenetic terms as the most original hose plant. This also explains some of their specific characteristics.
She begins her mostly consisting of insect prey in filled with rain water hoses. It has no cover over the hose input in contrast to other pitcher plants, that collects rainwater.
The Red pitcher plant produces unlike their relatives significantly less digestive enzymes and is therefore dependent on the resolution of their prey to the aid of living in rainwater bacterial cultures. An escape of trapped insects prevent downward hair in the hoses, and the very smooth surface of the lower hose zone. Like all pitcher plants luring their prey with sweet nectar and their attractive color scheme. Despite the " simple" design of the case, it is very successful at catching prey. Since the tubes of the Red pitcher plant are aligned predominantly terrestrial, their prey spectrum consists rather of ground-dwelling insects and other insects. A single tube can reach a length of 30 centimeters. The tubes do not die over the winter.
Dissemination
The species has the widest distribution of all pitcher plants. In the southern distribution area ( the southern New Jersey to the North East of Florida) one finds the Sarracenia purpurea subspecies ssp. venosa ( known in English as Southern ( Purple) Pitcher Plant called ) - it makes compared thicker and more hairy hoses, this subspecies is hardy only to a limited extent.
In several cases, the Red pitcher plant by plant lovers at appropriate locations outside their natural range was angesalbt. Some of these sites are naturalized, the earliest known in the Swiss Jura is about a hundred years old. Next to it Ansalbungen also found in Germany in Middle Franconia (thirty years old ), in the Lausitz (thirty years old ) and the Bavarian Forest. The deposits are considered vital, the plants reach a size of up to 45 centimeters and a coverage of up to 50 %. More Ansalbungen can be found in Europe in Ireland, in the English Lake District, in Sweden and in the U.S. on the coast of California's Mendocino County.
System
Already in 1601 described Clusius, accompanied by the first figure of the species and one of the earliest of a pitcher plant at all, a red pitcher plant peregrinum as Limonium in his Rariorum plantarum historia, saw in it so inaccurately a beach Lilac kind.
The 2001 separated by the Red pitcher plant Sarracenia rosea as an independent species is not uniformly accepted and shall be as far as venosa variety burkii the subspecies.
Among the pitcher plants Sarracenia purpurea is the most primitive kind of Sarracenia purpurea subsp dar.. venosa has a lighter bloom (light red to red) as Sarracenia purpurea subsp. purpurea ( dark red to violet-red ). The flower stalk reaches a height of 20 to 40 centimeters. The flowering period starts from the middle of March.
