Oxossia is a genus of flowering plants in the subfamily Turneroideae (Passifloraceae) consisting of 15 species. This genus was recently defined in 2019 after a phylogenetic analysis of Turnera justified the creation of the genus.
Description
The genus is characterized by its stipules, small flowers, congested inflorescences, "hairy" stamen and style, and the attachment of stamen to the floral tube. All members of the genus are heterostylous with the exception of O. dasystyla. The genus can be divided into two morphological groups: those with white petals and those with yellow pink or red petals.
