Though they are morphologically very similar, the two unique mountain populations of miniature Melocactus from Puerto Rico and Hispaniola (Dominican Republic) have been treated as different species. After contrasting several living plants and their cultivated descendants from both island-sites over the years, it is concluded that the minor vegetative differences that separate them do not justify species recognition. As a result, the recently described Melocactus pygmaeus Hoxey, Gdaniec and Ackerman from the steep slopes of Sierra de Cayey, Puerto Rico is hereby treated as a subspecies of the previously described Melocactus praerupticola Areces from the rocky cliffs of Constanza, in the central mountains of the Dominican Republic. Likewise, based on vegetative and floral characters, no apparent similarities were found between this praerupticola–pygmaeus complex and M. guitartii León from Cuba.

Abstract: We describe two new species of Ceropegia. Of these, Ceropegia pseudolugardiae Bruyns of sect. Phalaena H.Huber from Kenya and Tanzania has long been considered to belong to C. lugardiae N.E.Br. but has fibrous roots rather than the cluster of swollen, fusiform roots typical of C. lugardiae. This important feature has been much neglected, as the rootstock is absent from most herbarium specimens. Ceropegia pseudolugardiae is closely related to C. distincta N.E.Br. and C. zambesiaca Masinde & Meve, which all share the fibrous roots and differ in details of their flowers. The second species is C. lubangoensis Bruyns of sect. Laguncula H.Huber from Angola. This is distinguished from all others in this section by the considerably longer corolla-lobes.

Abstract: Cereus tubiflorus Pfeiffer was described in 1837 on the basis of material without known wild origin, and a contemporaneous illustration was recently designated as neotype. In order to stabilize the application of the name (as Echinopsis tubiflora (Pfeiffer) K. Schumann in current classifications) for a taxon from the Andean foothills of N Argentina, we here designate an epitype. Further, we clarify the place of valid publication of the name.
