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.

Ipomoea Pes-caprae
''Ipomoea pes-caprae'', also known as bayhops, bay-hops, beach morning glory or goat's foot, is a common pantropical creeping vine belonging to the family Convolvulaceae. It grows on the upper parts of beaches and endures salted air. It is one of the most common and most widely distributed salt tolerant plants and provides one of the best known examples of oceanic dispersal. Its seeds float and are unaffected by salt water. Originally described by Linnaeus, it was placed in its current genus by Robert Brown in 1818. Description ''Ipomoea pes-caprae'' is a prostrate perennial, often covering large areas; stems long-trailing often several metres in length, rooting at the nodes, glabrous. It has pink, fused petals with a darker centre. The fruit is a capsule containing 4 hairy seeds that float in water. Distribution This species can be found on the sandy shores of the tropical Atlantic, Pacific, and Indian Oceans. A similar species, ''Ipomoea imperati'', with white flow ...

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 ...
