Utricularia georgei Species Profile

Utricularia georgei Species Profile

Utricularia georgei is an annual bladderwort endemic to the Kimberley region of northern Western Australia.

Utricularia georgei is a small bladderwort that grows to around 15cm in height. The lower corolla lip is divided into three deep lobes that are rounded towards the edge. The upper corolla lip is small and upright, with a notch at the centre. The palate of the flower has an elongated yellow blotch. The spur is thin and dramatically thrust backwards, forming a horizontal plane with the lower corolla lip. The scapes have one or two blooms.

The species is known from the northern Kimberley region where it grows on seepages and soaks atop sandstone. I observed the plants north of Kalumburu during March. These seeps generally dessicate in the dry season.

Utricularia georgei is most similar to U. kamienskii in appearance, although their ranges do not overlap. Utricularia georgei is distinguished by its corolla spur, which is thrust backwards such that it forms a straight line relative to the lower corolla lip (the spur of U. kamienskii is thrust at an obtuse angle relative to the lower corolla lip).
