Pinguicula lusitanica is a carnivorous plant from the genus of fatty herbs ( Pinguicula ), Isoloba section. It was first described by Carl von Linné in 1753 as the third species of the genus.
description
Pinguicula lusitanica is a perennial plant with a temperate, heterophyllous habit . It grows in the form of a native rosette, its roots consist of numerous, fine roots. In contrast to the majority of the European species, it does not form a hibernacle for wintering .
leaves
The summer and winter rosette of the species consists of five to twelve elongated egg-shaped, 0.6 to 29 millimeters long and 3 to 8 millimeters wide green leaves , which are reddish in color along their veins and strongly curled up from the side. The leaves of the winter rosette are smaller than those of the summer rosette.
blossoms
The plant forms terminal single flowers on up to eight flower stalks between April and October. The plant is extremely fast-growing, they often bloom in the first year. The zygomorphic flowers are pale pink with a yellow sap mark and self-pollinating, the stigma is curved back into the anthers . The numerous seeds that are formed in the round seed capsule are 0.5 to 0.65 millimeters long and 0.2 millimeters wide.
Chromosome number
The number of chromosomes is 2n = 12.
Distribution and habitat
The species is widespread on the Atlantic coastal areas of Western Europe from Scotland and the Orkney Islands via Ireland, England, France, Spain and Portugal and occasionally on the coasts of the western Mediterranean (Morocco, Algeria, southern France). In France, isolated areas can also be found inland, but these are on the decline.
It colonizes nutrient-poor moors and often occurs in association with the mean sundew ( Drosera intermedia ) and the Dorset heather ( Erica ciliaris ).
