• Pultenaea glabra Benth. is a recently revised taxon which includes disjunct populations in Victoria, NSW, and Queensland. Victorian populations were previously described as Pultenaea weindorferi Reader, and listed as rare in Victoria. Pultenaea glabra is known from four locations in Victoria; it is locally abundant at the Bunyip and Lerderderg-Wombat localities, is uncommon at Wandin, and is in serious decline at Kinglake. Viable soil-stored seeds were present at all sampled locations, and seed germination was enhanced by heat pre-treatments, though germination of untreated seeds also occurred. Few mature plants remain at Kinglake and the population structure differed markedly from the other sampled populations. It has been suggested that the species requires a specific fire regime for regeneration, but it is likely that the severe decline in the Kinglake population is the result of grazing, rather than an inappropriate fire regime. At this site, germination is occurring but plants have not reached maturity, and the species is represented by only seedlings. Managing the species at Kinglake will require consideration of multiple factors, and reintroducing fire to the site at this stage may jeopardize seedling survival and result in local extinction.
