The eremophila ( Eremophila ) are an Australian endemic genus of the family of Figworts (Scrophulariaceae).

features

Eremophila deserti

Eremophila oldfieldii

The representatives of this genus are small to medium-sized shrubs, only a few species are small trees. The leaves are opposite or alternate. Many species have gray, hairy leaves as protection against radiation, others have leaves with a sticky surface as protection against evaporation.

The flowers are individually in leaf axils. The chalice and crown are fivefold. The calyx is free, the petals are fused. The crown is tubular and curved. The upper lip is usually two-lobed, the lower lip three-lobed. The flowers are rather large and often strikingly colored (white, cream-colored, yellow, orange, red, pink, purple or brown), and sometimes the calyx as well.

Around three quarters of the species are pollinated by insects ( entomophilia ), the others by birds ( ornithophilia ). The fruits are fleshy or dry capsule fruits with one to twelve seeds.

The number of chromosomes is x = 27.

distribution

The emus bushes are endemic to Australia. They grow mainly in the arid areas of the Mulga in Central and Western Australia. Because of its occurrence on extremely poor soils, many representatives are also called poverty bush ( poverty bush ).

Systematics

Eremophila hygrophana

Eremophila latrobei

Eremophila maculata

Eremophila nivea

Eremophila oppositifolia

Eremophila polyclada

Eremophila sturtii

Eremophila subteretifolia

The genus previously belonged to the Myoporaceae family, but this family was incorporated into the Scrophulariaceae family. The name emus bush ( emubush ) is based on the erroneous assumption that the fruits are eaten by emus and that the seeds are only able to germinate through the intestinal passage.
