Northern Serrate Dryandra  |  

Banksia serratuloides subsp. perissa

Status: Critically Endangered on the EPBC Act list

Dryandra serratuloides subsp. perissa, Family Proteaceae, also known as Northern Serrate Dryandra, is a low, compact shrub, growing to 1 m tall and 1.2 m in diameter, with crowded leaves on erect branches. The leaves, 19 cm long, are paler on the underside and divided almost to the midrib forming 20–33 long flat lobes which are quite rigid. The flower heads, held in the leaf axils, are axillary and surrounded by lanceolate bracts which are hairless on the back and with white woolly margins, which later become smooth. The yellow flowers, about 2.5 cm long, have a silky-hairy perianth. The long, hairless style has a narrow, furrowed, darker coloured stigmatic end. Flowering occurs from August to September. This species can be distinguished from Dryandra serratuloides subsp. serratuloides by its longer leaves with more lobes, longer inflorescence bracts, a later flowering time and a more northerly distribution. Northern Serrate Dryandra is now known as Banksia serratuloides subsp. perissa.

    Weeds also exacerbate grazing pressure and increase the fire hazard due to the easy ignition of high fuel loads produced annually by many weed species (DEC; 2009).

    Inappropriate fire regimes are a potential threat as the fire response to this subspecies is currently unknown.
