Common name

Origins

Derived from tropical South America (ie Brazil, French Guyana, Guyana and Suriname).

Plantings

Many are grown in gardens in Australia, especially in sub tropical and tropical regions. Many cultivars have been developed, which can range in flower color from yellow to pink or even brown chocolate. It is very popular in the Cairns area, in northern Queensland, and some local businesses put it in their corporate identity.

Distribution of the desired

Dynamics in Queensland's coastal district, and most often found in the northern part of the state. North Kennedy, South Kennedy, Port Curtis and Moreton pastoral districts. It is also naturalized in the northern coastal district of Western Australia.

Exiled abroad in China, southeast of the United States (ie Florida) and in some Pacific Islands (eg in American Samoa, Western Samoa, Fiji, Niue and Palau).

Habitate

Allamanda yellow (Allamanda cathartica) prefer damp, well-drained, soil in the tropics. Currently, primarily road and bushy weeds in the wet tropics of northern Queensland, but are also reported to grow along small rivers and disturbed natural vegetation in Western Australia.

Habitat

Vineyards or shrubs with several climbing rods (ie scandent shrubs). These often form into clumps as high as 2 m and 2-3 m wide, but can grow much higher when climbing over other vegetation (up to 6 m tall).

Distinguishing feature

a vine or climbing a bush with milk sap.

The leaves are rough and usually arranged in groups of three or four cigarettes.

The large bright yellow flowers are trumpeted with five lobes of spreading petals.

Its round fruit capsule (about 4 cm) is covered with a soft spine (about 1 cm long).
Trunk and Leaf The older stems are mostly woody and brownish, while the younger branches are generally green and not hairy (ie glabrous). The stems and leaves contain the sap of milk (ie latex).

The simplest leaves are arranged in groups of three or four along the branch (ie, leaves are speckled or vertical). They are carried on very short stalks (ie petioles) that are only 2-5 mm long and have egg-shaped stripes (ie obovate) rather elongated (ie, oval-lanceolate). This leaf (5-17 cm long and 2.5-6 cm wide) has a narrow narrowing base, an overall margin, and a pointed tip (ie, acuminate apex). They are somewhat shiny in appearance, relatively thick and rough in nature, and not hairy (ie glabrous).

Flower & Fruits

Large flowers (7-11 cm long and 5-7.5 cm wide) have five bright yellow petals that are about 4-8 cm long. This tube has a reddish mark on the inside and is covered with five disseminated lobes.

The flowers also have five sepals (8-22 mm long) attached to a grayish-colored tube that is smaller and greenish in the bottom (ie a petal tube). Each flower also has five stamens that go directly into the inside of the flower petals (ie a crown jewelry ornament) and a long style with two small branches at the end. The flowers are borne in a loose group (ie cymes) near the end of the tree trunk, each containing about ten flowers. Individual flowers are borne on short stalks (ie pedicles) about 5-7 mm and flower petals (ie corolla lobes) folded and twisted at buds. Flowering may be mostly during spring and summer.

The fruit is round (ie capsule) capsule (about 30-75 mm) sealed with a soft spine (about 1 cm in length). This fruit is rarely seen in cultivated plants. Seeds are somewhat flatenned (compressed), brown and slightly winged or have thin margins (ie membranes).

Reproduction and spreader

These species breed with seeds and can also be propagated through the stem segment.

Allamanda yellow (Allamanda cathartica) may be mostly dispersed in waste garden discharged along the roadside and in the bush. The seeds then dissolved from this initial infestation by wind and water. The rod segment can also spread to the drains during flooding.

Environmental Impac

Yellow allamanda (Allamanda cathartica) is regarded as an environmental weed in northern Queensland. It is one of a number of exotic ornamental vines that have become invasive in this region after escaping from garden plantings. This species was first recorded as naturalised in Queensland in 1945. By 1992, it was recognised as a weed of roadsides in the wet tropics region of northern Queensland, but it was not then considered to be a high priority environmental weed.

However, yellow allamanda (Allamanda cathartica) has continued to spread and is now widely naturalised in the rainforests of northern and central Queensland. It is now considered to be quite invasive in several National Parks in far northern Queensland and is common along roadsides between Silkwood and Tully. It also invades well-drained soils on the fringes of rainforests and paperbark swamps.

In fact, yellow allamanda (Allamanda cathartica) was recently ranked among the top 25 species on a prioritised list of weeds of the wet and dry tropics regions in northern Queensland. It is also listed as a priority weed in the Far North Queensland Natural Resource Management region, is a locally declared plant in Cardwell Shire, is regarded as an "undesirable plant" in the wet tropics World Heritage Area, and is thought to be adversely impacting upon natural systems in the Townsville City area.

This species also grows along creeks and roadsides, and in disturbed natural vegetation, in northern Western Australia. It was first recorded as naturalised in this state in 1993 and is also locally naturalised on creeklines on Koolan Island. Though it is not yet listed as naturalised in the Northern Territory, yellow allamanda (Allamanda cathartica) is also regarded as a potential weed in Aboriginal lands in the Northern Land Council area.

Other Impacts

All parts of this species are toxic to livestock and humans, and the sticky milky sap can cause skin irritation.

Legislation

This species is not declared or considered noxious by any state or territory government in Australia.

Similar Species

Two other closely related species are also commonly cultivated in northern Australia, bush allamanda (Allamanda schottii) and purple allamanda (Allamanda blanchetii). These species can be distinguished from yellow allamanda (Allamanda cathartica) by the following differences:

yellow allamanda (Allamanda cathartica) has hairless (i.e. glabrous) stems and leaves that contain a milky sap (i.e. latex).

a has a somewhat climbing habit and has relatively large yellow flowers (7-11 cm long and 5-7.5 cm across).
bush allamanda (Allamanda schottii) has hairless (i.e. glabrous)
stems and leaves that contain a clear sap. It has an upright shrubby habit and relatively small yellow flowers (4-6 cm long and about 4 cm across).
purple allamanda (Allamanda blanchetii) has hairy (i.e. pubescent) stems and leaves.
It has a climbing habit and has relatively large purplish flowers (about 10 cm long and 10 cm across).
