Scientific name: Scaevola macrophylla

Common name: Large-flowered Scaevola

Conventionally accepted as Scaevola macrophylla (CHAH 2011).

The Large-flowered Scaevola is an erect herb covered in rough, yellow hairs, that is woody at the base and grows to 40–60 cm in height. The leaves are ovate (broad at base and pointed at tip) or lanceolate (long and pointed at tip), and mostly toothed. The flowers are blue or purple, almost sessile (without a stalk) and in a terminal, leafy spike up to 15 cm long which is at first very dense, but afterwards lengthening (Bentham 1869; Carolin 1992b; Robinson & Coates 1995; Western Australian Herbarium 2006). The fruit is ovoid, approximately 3 mm in length, rugose (wrinkled, creased), with few scattered hairs (Carolin 1992b).

The Large-flowered Scaevola is endemic to Western Australia. It is known from three populations in the Cape Riche area near Albany (approximately 480 km south-east of Perth) where it was last recorded in 1987 as 'locally abundant' (WA DEC 2009a). Whilst the species has not been rediscovered, it is still considered to exist as soil-stored seed (WA DEC 2009a).

Anecdotal information suggests the area of occupancy for the species is less than 1 km² (WA DEC 2009a).

The species has not been well surveyed, with large areas of potential habitat not investigated (Robinson & Coates 1995).

The Large-flowered Scaevola grows in rocky loam soil with the parent soil material being laterite. The species occurs in association with Featherflower (Verticordia spp.) and Kunzea (Kunzea spp.) species (WA DEC 2009a) and is often found within or on the margins of forests (Carolin 1992b).

The flowering period for the Large-flowered Scaevola is from September to October (WA Herbarium 2006). The species is thought to be a short lived species that recruits post-fire (WA DEC 2009a).

The main identified threat to the Large-flowered Scaevola is inappropriate fire regimes, which may affect the long-term viability of the species (WA DEC 2009a).

Minister's Reasons for Recovery Plan decision

There should not be a recovery plan for Large-flowered Scaevola as the approved Conservation Advice (TSSC 2010as) for the species provides sufficient direction to implement priority actions and mitigate against key threats.

Management documents for the Large-Flowered Scaevola can be found at the start of this profile.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
