Description and ecology

Vegetative characteristics

Acacia pulchella grows as evergreen shrub, the plant height usually 0.5 to 1.5 m, rarely up to 3 meters and achieved. The bark of the branches is hairy or bald, depending on the variety. There are leaf axils usually one or two usually 2-20 mm long spines each wound dry (node ​​), sometimes less, to not exist.

The change-constant leaves are bipinnate. The petiole is 0.5 to 6 mm long. It's just a pair of leaflets of the first order with a length of 1 to 15 mm available. There are two to eleven second-order leaflets available; they are oblong to obovate or upside - lanceolate, 1-6 mm long, 0.5 to 2 mm wide, flat, green to bluish, hairless hairy until fluffy. The stipules are trockenhäutig and the side leaflets are 3 mm long. There are glands present in the axils of the first order leaflets.

Generative features

In winter and spring appear laterally in rudimentary racemose inflorescences total of about 3 mm long inflorescence axes one to three kopfige part inflorescences. The 1 to 15 (rarely to 20 ) mm long Blütenstandsschäfte the capitate partial inflorescences are hairy or bald, depending on the variety. Each spherical, kopfige part inflorescence contains 10 to 40, rarely up to 60 flowers. There are cover sheets available. The hermaphrodite flowers are radial symmetry, fünfzählig and golden yellow. The five sepals are fused to one-half to two-thirds of its length. There are five petals, many stamens, and a carpel available.

The narrow oblong legume is flat to slightly undulating, 1.5 to 5 cm long, usually 3 to 5 mm wide, hairy or bald with a thick border. The brown seeds with a length of 2.5 to 4.5 mm long and usually have an aril.

Ecology

Acacia pulchella is a fire to germinate, the seeds germinate only after it was a large fire in abundant quantity. Germination after small fires or in humid conditions occurs only in small degree.

Occurrence

Acacia pulchella is widespread in the south-west of the Australian state of Western Australia from Port Gregory to Cape Arid. It can be found near swamps or streams and prefers nutrient- poor, sandy soils, loamy soil rich and laterite.

The four recognized varieties differ mainly in plant height, presence of leaf hairs ( trichomes ) on the bark and the inflorescence stem, number and length of spines, and the size of the leaves:

• Acacia pulchella var glaberrima Meisn. (Acacia hispidissima DC. ): Height 0.5 to 2 ( to 3) meters.
• Acacia pulchella var goadbyi ( Domi ) Maslin ( syn. Acacia goadbyi Domi ): plant height ( 0.3 to ) 0.5 to 1.5 meters, sometimes spineless.
• Acacia pulchella pulchella var: natural height usually 0.5 to 1 ( 0.15 to 1.5 ) meters.
• Acacia pulchella var reflexa Maslin: Height 0.4 to 1 meter, sometimes spineless.
