Taxonomy, genetics and conservation: a preliminary study of the variation in Actephila lindleyi (Euphorbiaceae) a rainforest shrub

Abstract

Actephila lindleyi is a highly morphologically variable species. It occurs in disjunct populations in rainforests from Cape York to central New South Wales. Preliminary tests have shown variation between populations is matched by genetic variation at the enzyme and chromosome levels. Thus, taxonomic revision of this species should take this into account. Such taxonomic decisions have implications for conservation and management. For example, the overall conservation status of a widespread species with endangered populations might be much lower than the conservation status of each population when elevated to species status.
