rodents) are all heavily involved in the spread of this species. The seeds contain 23% protein, 6% fat and 40% soluble carbohydrate. Synonyms. The fat and hence energy content of the A. cyclops funicle is about six times greater than other Acacia species. It may also be naturalised beyond its native range in other areas, such as on the Eyre Peninsula, the Yorke Peninsula, and on parts of Kangaroo Island. Best germination was obtained by nicking the seed (scarification) and although putting the seed in boiling water also increased germination, heating for longer than 3 minutes soon reduced success. var.Acacia mirbelii Dehnh.Racosperma eglandulosum (DC.) Distribution in Portugal. Predators of seed crops include the Pink Cockatoo and many bugs, weevils and moths. Vol. The small yellow or golden-yellow flowers are stalkless (i.e. close-up of small globular flower clusters (Photo: Rob and Fiona Richardson), close-up of mature fruit with distinctive seeds surrounded by large red arils (Photo: Bruce Maslin), close-up of old seeds with faded arils (Photo: Steve Hurst at USDA PLANTS Database), Acacia cyclopis A.H. Mackay ex LoudonAcacia cyclopis F. Muell.Acacia cyclopis SweetAcacia eglandulosa DC.Acacia mirbeli Dehnh., ortho. Adults or larvae of 35 species of Coleoptera (beetles and weevils) were found on A. cyclops of which 11 species were also found on A. saligna. These two-species are now abundant. In New South Wales it is most commonly found along the coast and on the tablelands, but also extends into the eastern parts of the w… sessile) and densely arranged into globular clusters (5-7 mm across), each containing numerous (60-75) flowers. However it does produce useful firewood, Ross (1975). sophorae). Those feeding on the sap and twigs were most abundant. It may also be naturalised beyond its native range in other areas, such as on the Eyre Peninsula, the Yorke Peninsula, and on parts of Kangaroo Island. Loss rates were high and up to 97% of the seeds tested either germinated or rotted by the end of the first year. G. Don, Gen. Syst. Acacia cyclops is found along the coast of SW Australia and of mediterranean-climate South Australia, associated with naturally- and artificially-disturbed habitats. its elongated and flattened pods (up to 150 mm long) become twisted and coiled after opening. It is a serious menace in many parts of the Cape Province where it may form dense, impenetrable stands invading and displacing indigenous flora. The names used were Pt. A shrub or small tree usually growing 1-4 m tall, but occasionally reaching up to 7 m in height. orange or bright red) fleshy aril that surrounds its seeds. Dense, bushy, rounded, glabrous, spreading shrubs 2-4 m high, branching at or just above ground level often with foliage almost to the ground, obscuring the stems; branchlets angular and light greenish-brown but almost terete becoming dark brown with age, a conspicuous feature is the old legumes which often persist on the bush after the seeds have been shed. in Europe, southern Africa, and California in south-western USA), and is particularly widespread in South Africa. It is also naturalised in some parts of southern Victoria. These seeds are mainly dispersed by animals that consume them. Studies have demonstrated that birds, ants and small vertebrates (e.g. Acacia cyclops G.Don Coastal Wattle Gen.Hist. Immigration News. Heat treatment was not very effective. a pulvinus). An account of the distribution and dispersal of A. cyclops in Australia may be found in Gill (1985). regions, but especially in Africa and Australia. The shrubs are essentially coastal in naturally or artificially disturbed habitats mostly, but not wholly, on calcareous sands. (1981) studied the dispersal of A. cyclops by birds in the Cape Peninsula. Jones (1963) showed the seed weights of A. cyclops to be 40-41 mg and that of A. saligna (as cyanophylla) to be 18-21 mg. Used for stabilization in South Africa, it is spreading on sand and sandstone into coastal bush and heathland. The extent to which seeds would be distributed would depend on the ranges of the bird. Distribution Native to southwestern Australia, where it grows mostly on coastal sand dunes. He then attempted to separate A. cyanophylla from A. saligna considering that there were minor differences in the petal midrib and the funicle that could be used. It has invaded these same habitats in other parts of Australia, and has also become a concern in the semi-arid inland regions of south-eastern South Australia. As the seedling grows, each new 'leaf' has phyllodes that are more fully formed and the leaves at their tips are eventually reduced to nothing. The latter soon acquired the Afrikaan name "rooikrans" red wreath, a reference to the red funicle surrounding the seed. Once on the ground ants appear to be the principal agents for seed movement and at least six genera of ants may be active. The Australasian Virtual Herbarium (AVH) is an online resource that provides immediate access to the wealth of plant specimen information held by Australian herbaria.
