Alternanthera nodiflora (common name common joyweed) [4] is a species of flowering plant in the family Amaranthaceae. [1] [2] It is endemic to Australia, growing in all mainland states. [4] It is naturalised in Tasmania, over much of Africa, in Japan, and in Myanmar. [5]

Description

Alternanthera nodiflora is an erect annual herb. The branches are almost without a covering but the nodes are covered with dense intertwined hairs, and there are two lines of hairs along the branches. The leaves, too, are almost without a covering and are linear, 2-8 cm long and have smooth margins. The inflorescences are globular, and often clustered. The fruit is less than half the length of the perianth. The style is very short. [6]

Taxonomy and naming

It was first described by Robert Brown in 1810. [1] [2] The type specimen is BM001015779 (collected on the east coast of Australia); Isotypes are E00279928 (collected at Broadsound), P00622600 (all three collected by Brown). The name is accepted by the Council of Heads of Australasian Herbaria, [1] by Plants of the World online, [5] but is considered a synonym of Alternanthera sessilis by Catalogue of Life. [7]

The specific epithet, nodiflora, derives from the Latin, nodus,( "knot" or "node") and flos, floris ("flower") to give an adjective describing the plant as having flowers arranged in a knot-shaped inflorescence or flowering at the nodes. [8]

<i>Alternanthera</i> Genus of flowering plants

Alternanthera is a genus of flowering plants in the family Amaranthaceae. It is a widespread genus with most species occurring in the tropical Americas, and others in Asia, Africa, and Australia. Plants of the genus may be known generally as joyweeds, or Joseph's coat. Several species are notorious noxious weeds.

<i>Banksia paludosa</i> Shrub in the family Proteaceae native to New South Wales, Australia

Banksia paludosa, commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus Banksia. It is native to New South Wales, Australia, where it is found between Sydney and Batemans Bay, with an isolated population further south around Eden. There are two recognised subspecies, the nominate of which is a spreading shrub to 1.5 m (4.9 ft) in height, and subsp. astrolux is a taller shrub to 5 m (16 ft) high found only in Nattai National Park.

<i>Banksia sessilis</i> Species of plant of Western Australia

Banksia sessilis, commonly known as parrot bush, is a species of shrub or tree in the plant genus Banksia of the family Proteaceae. It had been known as Dryandra sessilis until 2007, when the genus Dryandra was sunk into Banksia. The Noongar peoples know the plant as budjan or butyak. Widespread throughout southwest Western Australia, it is found on sandy soils over laterite or limestone, often as an understorey plant in open forest, woodland or shrubland. Encountered as a shrub or small tree up to 6 m (20 ft) in height, it has prickly dark green leaves and dome-shaped cream-yellow flowerheads. Flowering from winter through to late spring, it provides a key source of food—both the nectar and the insects it attracts—for honeyeaters in the cooler months, and species diversity is reduced in areas where there is little or no parrot bush occurring. Several species of honeyeater, some species of native bee, and the European honey bee seek out and consume the nectar, while the long-billed black cockatoo and Australian ringneck eat the seed. The life cycle of Banksia sessilis is adapted to regular bushfires. Killed by fire and regenerating by seed afterwards, each shrub generally produces many flowerheads and a massive amount of seed. It can recolonise disturbed areas, and may grow in thickets.
