The type collection of Rondeletia inconstans has the calyx-lobes acute and narrowed at the apex, 0.3-0.4 mm broad, and of a narrower type than those of R. reflexa. The photo of the type specimen of the latter species shows the calyx-lobes oblong-lanceolate to broadly lanceolate, obtuse, and about 1 mm broad. Although Rondeletia orthoneura was described as having 5 calyx-lobes, study of the photograph of the type specimen shows only 4 to be present. Moreover, although the drawing accompanying the photograph shows 5 corolla-lobes, it is apparent from the photo as well as the characters noted for the plant that it is a tetramerous corolla and pertains to Arachnothrix rather than to Rondeletia. Schumann & Krause compared their plant with that having an unpublished herbarium name, “R. ferruginea Kl.”; the photo of this latter plant shows tetramerous flowers and the arachnoid indument of the hypanthium and corolla characteristic of Arachnothrix.
