Note
Venter & Verhoeven in S. Afr. Journ. Bot. 62: 27 (1996) stated that Preuss 151 (B†) was the holotype of Periploca preusii K. Schum. This was in effect a lectotypification, as several other collections had been cited in the protologue. Extant duplicates of two of the original syntypes have now surfaced – indeed they were cited by Venter & Verhoeven (1996), but not recognised as syntypes at the time. We therefore propose to overturn the earlier lectotypification, and designate the Kew duplicate of Welwitsch 4232 as the lectotype of this name – duplicates of this collection are distributed in a number of other herbaria. D.J. Goyder & H.J.T. Venter. Verdcourt 3598A, a fruiting specimen from K 7 (Voi Hotel, Teita District), has been determined as this species, but in the absence of flowers its identity is questionable.
