Revision of the genus Thysanotus R.Br. (Liliaceae)

The genus Thysanotus is currently considered to consist of 47 species, of which three ? T. fastigiatus, T. glaucifolius and T. lavanduliflorus (all endemic to Western Aus- tralia) ? are described and illustrated for the first time. The other species are fully de- scribed and their relationships with allied species discussed. Those for which illustrations did not previously exist have been illustrated. At the infraspecific level two species ? T. patersonii and T. tuberosus ? have had subspecies formally constituted. A series of 19 maps gives details of the geographical distribution of the species.
