Eremophila bignoniiflora

Eremophila bignoniiflora is spreading, weeping shrub that may reach a height of 5 metres by almost the same width. The branches are smooth and sticky.

It is a species inhabiting inland arid areas, occurring from the western parts of the north-western slopes in NSW (west from about Warialda), out to the north-western and far north-western plains, as well as the south western plains. It occurs over much of Queensland, extending across the entire state in some areas (Rockhampton-latitude), as far north as Karumba on the Gulf of Capentaria; found over the central parts of the Northern Territory and eastern to central parts of South Australia (as far west a snear Coober Pedy). It occurs in the north of Wesertn Australia and only in the very north-west of Victoria.

It occurs commonly on floodplains in dry sclerophyll woodland and arid shrublands, often on sandy-loams to sandy soils and alluvium.

Eremophila spp. mostly have simple and alternate leaves (sometimes opposite or whorled). In this species, leaves are light green, linear to lanceolate, to 20 cm long and 1.5 cm wide; hairless with margins entire or rarely with teeth.

Eremophila spp. have 5-merous flowers with the 5 petals usually fused into a tube (tubulate to campanulate) with 5 petal-lobes (often described as 2-lipped with 3 upper lobes and 2 lower), occurring in small-numbered clusters per leaf axil. Flowers are often curved. In this species, the flowers are large, tubular and usually cream with purple spots in the throat; to 40 mm long, and produced solitarily in leaf axils. Some plants have pale to deep pink blooms and the flowers of this species are considered amongst the largest in the genus. The flowering period extends from winter to spring with sporadic flowering at other times.

The fruit of Eremophila is either a dry or fleshy capsule which splits open into segments. In this species, it is ovoid to 20 mm long and 15 mm wide, somewhat fleshy and green.
