Reinstatement of Burchardia congesta (Colchicaceae)
KEIGHERY, G.J. AND MUIR, W.
Burchardia R. Br. is an endemic Australian genus of five species in the Colchicaceae. Burchardia umbellata R. Br. is a widespread taxon occurring disjunctly in temperate Eastern Australia and in south-west Western Australia. Studies on the morphology, ecology and anatomy of the Western and Eastern populations have shown marked discontinuities in character sets, leading to the recognition that each area is a seperate taxon. The name B. congesta Lindl. is re-instated for the Western populations and the name B. umbellata restricted to the Eastern populations.
