Species

Hoplestigma is a genus of flowering plants in the family Hoplestigmataceae.[1] Many botanists do not recognize this family and place Hoplestigma in Boraginaceae sensu lato or in Cordiaceae. [2]

Hoplestigma has two species. Both are rare trees of lowland jungle in West and Central Africa. [3]

One study of pollen suggested that Hoplestigma might be related to the family Ehretiaceae.[4] In a comparison of chloroplast DNA sequences in 2014, Hoplestigma formed a strongly supported clade with Coldenia and genera that have always been placed in Cordiaceae.[5] The authors of that study recommended that Hoplestigma and Coldenia be included in Cordiaceae.

The genus name Hoplestigma is derived from the Greek hople, "a hoof or a cloven hoof" and stigma, "a flower stigma". The botanical name is a reference to the deeply bifid style.[6]
