Scientific name: Lechenaultia laricina

Common name: Scarlet Leschenaultia

Conventionally accepted as Lechenaultia laricina (CHAH 2010).

An erect, multi-branched, bushy shrub 30–70 cm high and 20–30 cm wide with many of the branches curving inwards and sometimes suckering. The Scarlet Lechenaultia has small, fine leaves 5–11 mm long, which are densely crowded, terete (cylindrical but usually slightly tapering at both ends ) and fleshy in appearance. The bark is rough except on new growth.

Solitary flowers occur at the ends of branches, with sepals (modified leaves acting as petals) 5–7.5 mm long and a corolla (petals fused together to form a tube) 19–23 mm long, scarlet to orange-red in colour, and densely hairy and usually orange on the inside. The petal lobes have broad wings with a small point between. The inside of the petals are hairy at the base. Two of the petals are erect above the corolla tube but not joined. The style (part of the female reproductive organs) is straight, 13.5–19.5 mm long, and sparsely covered with glandular hairs. The fruit is 17–29 mm long (Carolin 1992b; Durell & Buehrig 2001; Graham & Mitchell 2000).

Whilst the Scarlet Leschenaultia was once regarded as common between Meenaar, Meckering and Northam, Western Australia, it is now known only from a few populations in farmland (Carolin 1992b). Known populations  include (Atkins 1998b):

The Scarlet Leschenaultia is known from flats, slopes and drainage lines in permanently wet, moist or dry conditions. Soils are brown, yellow, white or grey laterites, sands, loams (with gravel) or clays. It occurs in low woodland over low scrub and dwarf scrub (Atkins 1998b; Durell & Buehrig 2001; Morrison 1982). Where the habitat adjoins paperbark (Meleleuca spp.) swamps it is found in association with Flooded Gum (Eucalyptus rudis), Wandoo (E. wandoo), Slender Banksia (Banksia attenuata), Mohan (Melaleuca viminea), Jacksonia spp. and other Melaleuca spp. (Atkins 1998b; Brown et al. 1998; Durell & Buehrig 2001).

The Scarlet Lechenaultia is a pioneer species in disturbed areas (Graham & Mitchell 2000) including disturbed areas in farmland (Atkins 1998b; Brown et al. 1998).

Flowers have been recorded from October to January. The fruits are dehiscent capsules, which split open and release seeds. The Scarlet Leschenaultia is able to regenerate from the rootstock after fire (Atkins 1998b) or grazing (Durell & Buehrig 2001). Seed germination is also known to occur after fire (Atkins 1998b).

The Scarlet Lechenaultia is threatened by clearing for farmlands. It colonises disturbed sites, but growth and germination is often suppressed by weeds (Brown et al. 1998). It is known to tolerate some grazing as evidenced by observed re-sprouting in one population after grazing (Durell & Buehrig 2001). However, heavy grazing may be detrimental.

Prolonged drought caused high levels of mortality in the 1990s (Atkins 1998b). The ongoing impact of this threat is not known. The taxon's response to salinity or the root-rot fungus, Phytophthora cinnamomi, are not known.

The Declared Rare and Poorly Known Flora in the Narrogin District (Durell & Buehrig 2001) report outlines the following management actions for the Scarlet Lechenaultia in the Narrogin region:

  • Liaise with landowners on at least an annual basis.
  • Inspect populations annually, monitoring numbers and condition.
  • Maintain an ex situ population.
  • Conduct further surveys on similar soil and vegetation types, especially on conservation reserves throughout its natural range.
  • Investigate the species' response to environmental impacts.

Management documents relevant to Scarlet Leschenaultia are at the start of the 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.
