Alternanthera nodiflora var. linearifolia Moq. | |
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]
