Richard W Jobson

Abstract


Utricularia blackmanii R.W.Jobson from igneous regions in northern Queensland (Australia) is described as new and is considered to be a member of Utricularia subg. Polypompholyx section Pleiochasia. The distribution and habitat preferences of this species are described and the morphological differences between U. blackmanii and species with which it was confused previously are discussed. Specifically, this new species is distinguished from U. dichotoma Labill., U. hamiltonii F.Lloyd, U. fistulosa P.Taylor, U. singeriana F.Muell., U. terrae-reginae P.Taylor, U. triflora P.Taylor, and U. tubulata F.Muell. by means of a diagnostic key.
