Eremophila undulata, commonly known as wavy-leaved eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a small shrub with greenish-brown flowers and leaves that have a wavy margin.
Description
Eremophila undulata is a shrub which grows to a height of between Шаблон:Convert and which has branches covered with long, white, branched hairs and persistent leaf bases. The leaves are arranged alternately along the branches and have stalks Шаблон:Convert long which are covered with hairs like those on the branches. The leaf blades are oblong to elliptic in shape, mostly Шаблон:Convert long, Шаблон:Convert wide, covered with branched hairs and have wavy margins.[1][2]
The flowers are borne singly in leaf axils on hairy, S-shaped stalks Шаблон:Convert long. There are 5 green, overlapping, egg-shaped to oblong sepals which are Шаблон:Convert long and mostly only hairy on their outer surface. The petals are Шаблон:Convert long and are joined at their lower end to form a tube. The petal tube is greenish-brown or yellowish-green with glandular hairs on both inner and outer surfaces. The 4 stamens extend beyond the end of the petal tube. Flowering occurs from June to July and is followed by fruit which are dry, almost spherical, Шаблон:Convert long and have a glabrous, papery covering.[1][2]
Taxonomy and naming
Eremophila undulata was first formally described by Robert Chinnock in 1980 and the description was published in Journal of the Adelaide Botanic Garden.[3][4] The type specimen was found by Alex George in 1974, Шаблон:Convert south of Neale Junction in the Great Victoria Desert.[3][2] The specific epithet (undulata) is a Latin word meaning "wavy"[5] referring to the margins of the leaves.[1]
Distribution and habitat
This eremophila is only known from a few small areas north of Rawlinna in the Great Victoria Desert biogeographic region[6][7] near where the type specimen was found. It is common in those locations, growing in brown sandy soil in association with mallee and hummock grasses.[1][2]
Conservation
Eremophila undulata is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[6] meaning that is poorly known and from only one or a few locations.[8]
Use in horticulture
Although its flowers are greenish, the flowers of this eremophila are produced in large numbers and are attractive to nectar-feeding birds. The wavy leaves are an added attraction. It can be grown from seed, from cuttings or by grafting onto Myoporum and the shrub grows best in well-drained soil in a sunny position. It only requires occasional watering during a long dry spell and is only damaged by the most severe frosts.[9]
