Plectocolea ovalifolia

The morphological differences between Plectocolea ovalifolia and Solenostoma infuscum ( var. infuscum ) are small (only uniformly oval leaves are significant). The size of plants and purple rhizoids are not important differences as the same size and purple rhizoids are known also in Solenostoma infuscum . However, according to molecular data ( Bakalin & Vilnet 2012: 569) it probably represents a good taxon of specific rank (belonging to different clades) and they elevate Plectocolea infusca var. ovalifolia to the species rank, Plectocolea ovalifolia . A transfer to Solenostoma is necessary.
