Eremophila praecox |
Eremophila praecoxis aflowering plantin the figwortfamily,Scrophulariaceaeand isendemictoAustralia.It is a small, broom-like shrub with small leaves and purple and white flowers.
Description
[edit]Eremophila praecoxis a broom-shaped shrub which grows to a height of between 0.3 and 1.5 m (1 and 5 ft). The branches have a covering of branched hairs, especially near the tips and are also slightly sticky near the ends due to a covering ofresin.The leaves are mostly arranged in opposite pairs and are linear in shape to almost cylindrical, mostly 5–11 mm (0.2–0.4 in) long, about 1 mm (0.04 in) wide, sparsely hairy and sticky when young but becomeglabrousas they mature.[2][3]
The flowers are borne singly, sometimes in pairs in leaf axils on hairy stalks 2–5 mm (0.08–0.2 in) long. There are 5 green to purplish-black, egg-shaped to narrow lance-shaped, hairysepalswhich are 1.8–3.5 mm (0.07–0.1 in) long. Thepetalsare 9–14 mm (0.4–0.6 in) long and are joined at their lower end to form a tube. The petal tube is purple, tinged white on the outside, while the inside of the tube and lower part of the lobes are white, spotted purple. There are a few hairs on the outside of the petal tube but the inside surface of the petal lobes is glabrous while the tube is filled with long, soft hairs. The 4 stamens extend slightly beyond the end of the petal tube, including in the bud. Flowering occurs from October to December and is followed by fruits which are dry, woody, cone-shaped to oval-shaped with a pointed end and about 3.5–5 mm (0.1–0.2 in) long and hairy.[2][3]
Taxonomy and naming
[edit]This species was first formally described byRobert Chinnockin 2007 and the description was published inEremophila and Allied Genera: A Monograph of the Plant Family Myoporaceae.[4]Thespecific epithet(praecox) is aLatinword meaning "too early ripe", "premature" or "precocious",[5]referring to the anthers which protrude from the flower buds.[2]
Distribution and habitat
[edit]Eremophila praecoxoccurs nearWidgemooltha,CoolgardieandKalgoorlie[2][3]in theCoolgardiebiogeographic regionsofWestern Australia[6]and as scattered individuals in the western part of theEyre PeninsulainSouth Australia.It grows in red-brown sandy loam with other eremophila species.[2][3]
Conservation
[edit]E. praecoxis classified as "Priority One"by the Western Australian GovernmentDepartment of Parks and Wildlife,[6]meaning that it is known from only one or a few locations which are potentially at risk.[7]
Use in horticulture
[edit]This eremophila is a dainty shrub with delicate blue to purple flowers. It can be propagated fromcuttingsor bygraftingontoMyoporumrootstockand grown in a wide range of soil types, including clay. A hardy shrub, it is both frost and drought tolerant, requiring only the occasional watering during a long drought.[8]
