Eremophila jucunda
Eremophila jucunda is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. It is a small to medium-sized shrub with hairy branches and leaves, lance-shaped to egg-shaped leaves and cream-coloured, lilac or purple flowers.
Description
Eremophila jucunda is a small to medium shrub, depending on its habitat, growing to about tall on hard, stony clay to on hillsides. Its branches and leaves are covered with grey or lemon-yellow branched hairs, especially densely when young. The leaves are lance-shaped to egg-shaped, mostly long and wide.The flowers are borne singly in leaf axils on a stalk long covered in hairs similar to those on the leaves. There are 5 pale yellowish-green to purplish-brown, linear to lance-shaped sepals which are mostly long but which enlarge after flowering. The sepals are covered with hairs similar to those on the young leaves. The petals are long and are joined at their lower end to form a tube. The petal tube may be white, cream-coloured, violet or purple on the outside and white, sometimes with purple spots inside. The outer surface of the petal tube and its lobes are mostly glabrous but the inside of the tube is filled with long hairs. The 4 stamens are fully enclosed in the petal tube. Flowering occurs from July to September and is followed by oval-shaped to conical fruits with a pointed end and which are long.
Taxonomy and naming
The species was first formally described by Robert Chinnock in 2007 and the description was published in Eremophila and Allied Genera: A Monograph of the Plant Family Myoporaceae. The specific epithet is a Latin word meaning "pleasant", "agreeable" or "delightful".Two subspecies are recognized in the Australian Plant Census:
- Eremophila jucunda subsp. jucunda which has cream-coloured to lilac flowers, bright yellow hairs on the young branches, leaves and sepals, and hairs on the outside of the petal tube;
- Eremophila jucunda subsp. pulcherrima which has lilac-coloured to light purple flowers, grey hairs on the young growth and petals which are glabrous on the outside.
Distribution and habitat
Eremophila jucunda subsp. jucunda is widespread on hills, ranges and plains between Sandstone and Mount Vernon in the Gascoyne, Murchison, Pilbara and Yalgoobiogeographic regions. Subspecies pulcherrima grows mostly on slopes and rocky hills between Paraburdoo and Newman in the Gascoyne, Murchison and Pilbara biogeographic regions.
