Alternanthera denticulata (common name lesser joyweed) is a small prostrate white-flowering herb in the Amaranthaceae family. [4] It is native to all states and territories of Australia, [5] New Guinea, and the North Island of New Zealand. [3] It is also one of the food plants of the varied eggfly, Hypolimnas bolina nerina. [6]

The species was first described in 1810 by Robert Brown. [1] [2]

Description

Alternanthera denticulata is a prostrate to erect perennial herb, whose stems root at the nodes. The stems are green flushed pink, and sparsely hairy to being without a covering. The nodes are tomentose (that is, covered with dense intertwined hairs). The leaves are (20-)30-80 by 6–12 mm, and a light green, yellow green or flushed pink, with both the midrib and lateral veins being pink. The leaf margins are finely toothed, [7] or entire. [5]

Habitat and flowering

In Western Australia, it grows on both sand and clay soils, on the banks of creeks, rivers and swamps, flowering from April to August. [4] On the North Island of New Zealand, it is found on coastal and lowland wetlands, lake margins and other damp ground, flowering from January to December. [7]

Conservation status

In New Zealand, it has been assessed by the Department of Conservation as "Data Poor" but "Secure Overseas". [8]
