Summer rosette of Pinguicula cyclosecta
Pinguicula cyclosecta is a carnivorous plant from the genus of the fatty herbs ( Pinguicula ) in the section Orcheosanthus . It wasfirst describedin 1963 by Siegfried Jost Casper based on collections from 1948 .
The dense, down-to-earth rosette has a diameter of up to 6 centimeters and consists of up to 25 leaves. The upside-down, spatulate leaves with an almost succulent character are colored strongly blue-violet on the slightly ciliate edge, an unmistakable feature of the species. On the surface, the leaves are smooth from the catching secretion with which it catches small insects (e.g. mosquitoes ) and once prey is obtained, digested by enzymes . Towards winter the plant forms a winter rosette consisting of numerous, small and strongly ciliate leaves with a diameter of only up to 2.5 centimeters, the winter leaves are not carnivorous.
From May to July, Pinguicula cyclosecta blooms on one to three three to five centimeters high flower stalks growing from the center of the rosette with terminal zygomorphic , long-spurred individual flowers . The flowers are up to 3 centimeters in diameter and (with spur) up to 3.5 centimeters long and purple, the five corolla lobes are evenly rounded, the epithet cyclosecta refers to this feature .
The number of chromosomes is 2n = 22.
Pinguicula cyclosecta is endemic to Mexico in the Sierra Madre Oriental mountains . It grows there between cushions of moss and in limestone crevices that are soaked by seepage water and that fall almost completely dry in winter. The locations are turned away from the sun, windy and cool.
