Abstract

Androcalva perlaria is a threatened endemic flora species, numbering less than 400 plants across eight populations in south­ western Australia. The species is gynodioecious, sexually dimorphic and pollinated by generalist invertebrates. Physical seed dormancy was broken in situ by fire or ex situ by wet heat indicating that recruitment required disturbance. An ex situ orchard produced a higher quantity of seed of comparable weight to in situ seed and explants were micropropagated and cryopreserved in vitro, which signified suitable sources for conservation actions. This study expands ex situ conservation options for A.
perlaria, and utilises life history to provide targeted conservation.
