Vernacular names
English: Squarestem


Melanthera, squarestem,[5] is a genus of flowering plants in the daisy family, Asteraceae, native to North and South America, as well as Africa, Asia and Oceania, including Hawaiʻi.[6][7][8][9][10]

The generic name means "black anther."[11]

The most common species of this genus is Melanthera biflora, found in the coastal areas and islands of the tropical belt of the Indo-Pacific region.[12] Together with Portulaca oleracea, Ipomoea pes-caprae and Digitaria ciliaris, Melanthera biflora is usually one of the first species colonizing degraded or altered environments in tropical zones of the planet.[13]

Despite their general hardiness, leaves of Melanthera species are often attacked by rusts such as Uromyces columbianus and Uromyces martinii.[14]

Taxonomy

There are difficulties regarding the classification of this genus for its affinities are uncertain. Further studies are needed to clarify its taxonomic and phylogenetic relationships.[15][16]
