Melanthera
''Melanthera'' (common name: squarestem), is a genus of perennial flowering plants in the family Asteraceae, native to North and South America, as well as Africa, Asia and Oceania, including Hawaii. 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. 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. Despite their general hardiness, leaves of ''Melanthera'' species are often attacked by rusts such as ''Uromyces columbianus'' and '' Uromyces martinii''. 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.

Julius Von Röhr
Julius Philipp Benjamin von Rohr (1737–1793) was a Prussian-born botanist and plant collector, naturalist, medical doctor and watercolourist, in Danish service who sent many plants to Europe from South America and the West Indies. He collected male ''Myristica fragrans'' flowers on the Isle de Cayenne in about 1784. Career He created the genus ''Melanthera'' which is closely related to ''Bidens'' in 1792, and is commemorated by the monotypic genus ''Rohria'' Schreb., native to French Guiana This botanist is denoted by the author abbreviation when citing a botanical name. Von Rohr was an immigrant to Denmark, and in 1757 was appointed as municipal buildings inspector and government land surveyor of the Danish West Indies, now known as the United States Virgin Islands. The Danish crown also commissioned a study of the natural history of the islands. Von Rohr started a botanic garden in Christiansted on the island of St. Croix, corresponding with noted natural history scientists ...
