Melanthera (common name: squarestem),[3] is a genus of perennial[4] flowering plants in the family Asteraceae, native to North and South America, as well as Africa, Asia and Oceania, including Hawaiʻi.[5][6][7][8][9]
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.[10] 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.[11]
Despite their general hardiness, leaves of Melanthera species are often attacked by rusts such as Uromyces columbianus and Uromyces martinii.[12]
Taxonomy
[edit]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.[13][14]
