Taxonomic and Nomenclatural notes on Lechenaultia R.Br. (Goodeniaceae)

Abstract

There have been a large number of nomenclatural and taxonomic problems within Lechenaultia, and these are resolved here. A total of 24 names are lectotypified, two neotypes are chosen, a series of misapplied names is elucidated, and L. agrostophylla is synonymised under L. filiformis for the first time. As well, L. brevifolia, L. lutescens and L. papillata are described as new species, and the considerable morphological variation within several of the species is reported in detail. The phylogenetic relationships within the genus are also re-appraised, the sectional delimi- tations are re-defined and section Patentes is described as new.
