Phylohydrax is a genus of plants in the family Rubiaceae. Its species are native to Madagascar, Tanzania and South Africa. [1]

Taxonomy

The genus Phylohydrax was established by Christian Puff in 1986 to accommodate two species previously placed in the genus Hydrophylax . The two genera were distinguished on morphological grounds, in particular the detailed structure of the flowers. Phylohydrax species are heterostylous unlike those of Hydrophylax. [2] Puff placed the genus in the tribe Spermacoceae, a placement supported by more recent sources. [3]

Species

As of March 2023, Plants of the World Online accepted two species: [1]

<span class="mw-page-title-main">Rubiaceae</span> Family of flowering plants including coffee, madder and bedstraw

Rubiaceae is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,100 species in about 580 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee; Cinchona, the source of the antimalarial alkaloid quinine; ornamental cultivars ; and historically some dye plants.

<span class="mw-page-title-main">Charlotte M. Taylor</span> U.S. botanist

Dr. Charlotte M. Taylor is a botanist and professor specialising in taxonomy and conservation. She works with the large plant family Rubiaceae, particularly found in the American tropics and in the tribes Palicoureeae and Psychotrieae. This plant family is an economically important group, as it includes plant species used to make coffee and quinine. Taylor also conducts work related to the floristics of Rubiaceae and morphological radiations of the group. Taylor has collected plant samples from many countries across the globe, including Chile, Colombia, Costa Rica, Panama, and the United States of America, and has named many new species known to science from these regions. As of 2023, Taylor has authored 500 land plant species' names, the third-highest number of such names authored by any female scientist.
