The species of Ceropegia found in the Cape Province of South Africa are reviewed with particular reference to their occurrence in the field. A classification is proposed which departs from that put forward in recent literature: 15 species are discussed and the following new combinations are made: C. fimbriata subsp. connivens, C. fimbriata subsp. geniculata, C. africana subsp. barklyi and C. linearis subsp. tenuis. The species C. dubia is regarded as a synonym of the tropical C. meyeri-johannis and is probably not indigenous to the Cape. Information on inflorescence structures found in the Cape species, habitats and distribution is provided and each taxon recognised is illustrated.

Die kapländischen Arten der Gattung Ceropegia werden mit besonderer Berücksichtigung der Verbreitungsverhältnisse bearbeitet. Die vorgeschlagene Klassifikation unterscheidet sich in einigen Punkten von modernen Einteilungen. 15 Arten werden diskutiert und die folgenden Neukombinationen werden veröffentlicht: C. fimbriata ssp. connivens, C. fimbriata ssp. geniculata, C. africana ssp. barklyi and C. linearis ssp. tenuis. Ceropegia dubia wird als Synonym der tropischen C. meyeri-johannis betrachtet und ist im Kap vermutlich nicht einheimisch. Alle anerkannten Arten sind abgebildet; zusätzlich werden Informationen über Infloreszenzbau, Standort und Verbreitung gegeben.

A synopsis is given of the species of Sedum recorded from Ethiopia, together with a key for their identification. Seven species are reliably recorded, of which three, S. baleënsis M. Gilbert, S. mooneyi M. Gilbert and S. glomerifolium M. Gilbert, are described as new. The status of two further species is queried.

This is the third instalment of an annotated list of Mammillaria names, continued from Bradleya 2: 65–96 (1984). A change of name is suggested for M. microcarpa Engelm., to M. milleri (B. & R.) Boed., as the former name was not validly published (provisional name).

The original German text of Ehrenberg's ‘Beitrag’ (Linnaea 19: 337–368. 1846) is reprinted, together with an English translation, an introductory biographical note, notes on the identification of the plants mentioned, a sketch map of localities, and indexes to plant- and place-names.

Der Nachdruck der deutschen Original-fassung von Ehrenberg's ‘Beitrag’ (Linnaea 19: 337–368. 1846) wird von einer englischen Uebersetzung, einer einführenden Bibliographie, Bemerkungen zur Identifikation der aufgeführ-ten Pflanzen, einer Karte der erwähnten Ortschaften, sowie einem Index der Pflanzennamen und Ortschaften begleitet.

A list is given of the new names and combinations not validly published in C. Backeberg's post-1957 contributions (‘DieCactaceae’, ‘DescriptionesCactacearum Novarum’ II and III, ‘Das Kakteenlexikon’, und a few papers in journals), together with a short indication of the ICBN-articles which have been transgressed.

A classified list of periodicals devoted entirely or in part to succulent plants is given. Relevant bibliographical information is provided for each title, as well as a consistent set of abbreviations. Important sub-titles, alternative titles, etc., are always cross-referenced to the main entry. Two appendices list the periodicals according to publishing country and subjects, respectively.
