Utricularia regia

Utricularia regia is an annual bladderwort described in 2009 from the Sierra Madre del Sur of Guerrero, Mexico. It grows among mosses and Selaginella on wet rocks in pine forest and flowers in September and October. It is known from very few collections and is essentially absent from cultivation, so growing it means raising seed-grown annuals through a short, cool, wet summer.
