Achyranthes splendens, commonly called the Maui chaff flower, is endemic to the Hawaiian Islands.

Achyranthes mutica (also called Blunt Chaff Flower) is a species of plant in the Amaranthaceae family.

Blunt Chaff Flower (Achyranthes mutica)

Alternanthera caracasana is a species of flowering plant in the amaranth family known by the common names khakiweed, washerwoman and mat chaff flower.

Chamissoa altissima (False Chaff Flower ) is a plant native to North and South America, and it specially grows up in the Cerrado vegetation in Brazil.

Achyranthes (Cyathula) has properties that inhibits collagen-induced arthritis and acute edema.

Blunt Chaff Flower (Achyranthes mutica)

The larvae feed on Achyranthes, Cocculus, Cyclea, Menispermum and Tiliacora species.

This plant is similar to Achyranthes arborescens, an endemic from neighbouring Norfolk Island, but is a smaller, more compact shrub growing up to 2m tall with a 2m spread.

Achyranthes atollensis (also called Atoll Achyranthes or Hawaii Chaff Flower) was a species of plant in the Amaranthaceae family.

Some plants or fungi that produce phytoecdysteroids include Achyranthes bidentata, Tinospora cordifolia, Pfaffia paniculata, Leuzea carthamoides, Rhaponticum uniflorum, Serratula coronata, Cordyceps, and Asparagus.

The most pressing threats to populations of Achyranthes splendens are the destruction of remaining habitat for development and competition from invasive plants, especially the parasitic vine known as love-vine or dodder (Cassytha filiformis).

The larvae feed on Achyranthes species, including Achyranthes aspera, Achyranthes bidentata and Achyranthes japonica.

Measures currently being taken to protect populations of Achyranthes splendens and other threatened plant species in Hawaii include weed control, conservation of plants and seeds in botanical gardens and seed banks, and preservation of remaining intact habitat.

Most significantly, two novel triterpene glycosides isolated from achyranthes have been shown to be 1,000 times more potent than Sialyl Lewis X (SleX), an important blood group antigen that inhibits excess recruitment of neutrophils to injured tissues.

Achyranthes bidentata Blume (English common name: Ox Knee, Chinese: Niu Xi) is a species of Achyranthes that grows in India, Nepal, China, and Japan.
