Applequist, W.L. (2020). A revision of Homalium sect. Rhodonisa (Salicaceae) endemic to Madagascar. Candollea 75: 245–268. In English, English & French abstracts.

Homalium sect. Rhodonisa (Tul.) Sleumer is endemic to Madagascar and has included three recognized species. A new revisionary treatment of the section is presented and an identification key is provided. Twelve species are recognized, of which seven are newly described: Homalium analavelonae Appleq., Homalium ihosyense Appleq., Homalium megaphyllum Appleq., Homalium phillipsonii Appleq., Homalium pseudoracemosum Appleq., Homalium rakotovaoi Appleq., and Homalium vohitsiandrianense Appleq. Two lectotypes are designated. Taxonomic novelties are provided with line drawings or scans of their holotypes. Risk of extinction assessments indicate that two taxa are “Critically Endangered”, one is “Endangered” and four “Vulnerable”. Occasional hybridization is observed. Some specimens are not classifiable and it is possible that other unrecognized species exist.
