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]
