This rare species was recently collected by Dr. Marloth in the Calvinia Division, and to our knowledge has not been collected since the late Dr. Bolus discovered it on the Nieuwveld Mountains near Fraserburg over thirty years ago. Polyxena is a small endemic genus of about a dozen species, the majority of which are very little known, as most of them have not been collected since they were first found by the early Cape botanical collectors. Baker, who described and figured this species in Hooker’s Icones, remarks, “The affinity of this interesting novelty is evidently close with Massonia rugulosa of Lichtenstein and M. marginata of Willdenow, of neither of which we possess specimens in the Kew Herbarium.” Both of them fall under the genus Polyxena, as defined in the Genera Plantarum. Specimens preserved in the National Herbarium, Pretoria (Herb. No. 1448).
