Ten isozyme systems were investigated by polyacrylamide gel
electrophoresis to discriminate Blandfordia species grown
under in vitro conditions. Peroxidase (PER), esterase (EST) and
acid phosphatase (ACP) systems separated all four Blandfordia
species. Glutamate oxolacetate transaminase (GOT) and superoxide dismutase
(SOD) system, did not separate Blandfordia species well. Glutamate
dehydrogenase (GDH), leucine amino peptidase (LAP), alcohol dehydrogenase
(ADH) and alkaline phosphatase (LAP) isozyme systems were also
investigated, but were not detected. An isolated tableland population of B.
grandiflora from Gibraltar Range included in this study is believed to
have evolved in isolation as a distinct group and requires further investigation.
