Beskrivelse
R. eudoxum var. brunneifolium (I. B. Balfour & Forrest) D. F. Chamberlain: Større blade 7-9 cm og med tyndt brunt indument.
R. eudoxa aff. har tydeligt hvidt indument (var. mesopolium) og er (derfor tæt på / eller er) R. sanguinerum. K. Cox mener denne aff. og arten blot er hybrider mellem R. selense og R. sanguinerum (hvilket ikke forklarer hårdførheden HE). Flere arter i Neriiflora har sparsomt / intet indument som temenium, parmulatum, aperanthum. R. eudoxum har desuden kirtlede grene, bladstilke, calyx og kapsler / ovarie i modsætning til R. sanguinerum.
