The velvety grey leaves of Hermannia flammula are round-tipped and folding in along the midribs.
H. flammea leaves are greener and not velvety, toothed near their tips. H. flammula leaves are no more than 5 mm near the tips, those of H. flammea wider (Curtis-Scott, et al, 2020; Vlok and Schutte-Vlok, 2015; iNaturalist).
