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]
