A revision of 45 South African species of Argyrolobium is presented comprising
nomenclature, typification, recorded distributions and full descriptions. In an
attempt to reduce confusion between subtly different species, diagnostic characters
are listed and comprehensive illustrations are provided. The dissertation includes
numerous taxonomic and nomenclatural changes.
Currently two sections are recognised based on fruit morphology. This is replaced
by a system of five new sections based on morphological, micromorphological and
phytogeographical evidence.
Constraints and advantages of floral dimorphism and monomorphism are discussed
with respect to the fecundity and distribution of sections. It is proposed that the
occurrence of facultative cleistogamy in two sections has enhanced their success
and distribution.
Generic and specific phylogeny is interpreted using models generated through
cladistic methodology. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1994.
