Eremophila Oppositifolia , широко известная как Weeka , двойная листья эму и горного сандалового дерева, [ 2 ] является растением в фигуртов семействе , Scrophulariaceae , и является эндемичным для Австралии . Это кустарник или маленькое дерево с листьями, расположенными в противоположных парах и имеет кремовые или иногда цветные цветы с бордовым цветом.

Описание
[ редактировать ]Eremophila Oppositifolia - это кустарник или небольшое дерево, которое растет до высоты 1–5 метров (3–20 футов), иногда до 10 метров (30 футов). Его ветви, листья и цветочные стеблы покрыты слоем тонких волосков, прижатых к поверхности. Ветви грубые из -за постоянных оснований листьев и иногда становятся голыми с возрастом. Листья расположены в противоположных парах вдоль ветвей и имеют линейную или почти цилиндрическую форму и часто имеют крючок. Они составляют 29–120 миллиметров (1–5 дюймов) длиной, 0,9–7 миллиметров (0,04–0,3 дюйма) шириной, покрытые тонкими волосками, прижатыми к поверхности, а молодые листья также имеют желтовато -железистую волоска на нижней поверхности.

The flowers are borne singly or in groups of up to 4 in leaf axils on hairy stalks 3–10.5 mm (0.1–0.4 in) long. There are 5 hairy, spoon-shaped to lance-shaped sepals which are mostly 7–18 mm (0.3–0.7 in) long and which are cream-coloured or brown. The petals are mostly 20–30 mm (0.8–1 in) long and are joined at their lower end to form a tube. The petal tube is cream-coloured with a pink tinge, pink, red or (rarely) maroon. The tube and its lobes are glabrous apart from the margins of the lobes, and the inside of the tube which is hairy. The 4 stamens extend slightly beyond the end of the petal tube. Flowering occurs from winter to early summer[3] and the fruits which follow are oval to cylindrical in shape and 4–7 mm (0.2–0.3 in) long.[2][3][4][5]
Taxonomy and naming
[edit]The first formal description of this species was published by botanist Robert Brown in 1810 in Prodromus florae Novae Hollandiae.[7][8] The specific epithet (oppositifolia) is derived from the Latin words oppositus meaning "on the other side" or "contrary"[9]: 73 and folia meaning "leaves".[9]: 94
The names of three subspecies are accepted by the Australian Plant Census:
- Eremophila oppositifolia R.Br. subsp. oppositifolia[10] has leaves that are almost cylindrical in shape, often flattened or channelled on the lower surface and 1–3 mm (0.04–0.1 in) wide;[2]
- Eremophila oppositifolia subsp. angustifolia (S.Moore) Chinnock [11] has leaves that are cylindrical in shape, not flat, firm, erect and 1–3 mm (0.04–0.1 in) wide;[2]
- Eremophila oppositifolia subsp. rubra (C.T.White & W.D.Francis) Chinnock [12] has leaves that are flat and 3–7 mm (0.1–0.3 in) wide.[2]
Distribution
[edit]Subspecies oppositifolia is widespread and common from the Eyre Peninsula and Gawler Ranges in South Australia eastwards to south-western New South Wales and north-western Victoria in clay-loam in woodland and shrubland. Subspecies angustifolia is widespread and common in Western Australia and in isolated locations in South Australia, growing in a range of soils in mulga and Eucalyptus woodland. Subspecies rubra is found from western Queensland to western and central New South Wales west of Condobolin, usually growing in woodland.[2][3]
Use in horticulture
[edit]This large eremophila has attractive foliage and the colourful sepals extend its flowering period. It is a good feature plant but can also be used as a windbreak or screening plant. Propagation from cuttings is easy and the shrub will grow in a wide range of soils, including clay in either full sun or partial shade. It will tolerate long droughts but occasional watering will help to ensure a good flowering season. Light frosts are tolerated without damage but heavy frosts may cause the loss of leaves.[13][14]
Conservation
[edit]Weeooka is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[15]
