Published: Nos 1–63 (many out of print). Discontinued after No. 63. ANNALS OF KIRSTENBOSCH BOTANIC GARDENS A series devoted to the publication of monographs and major works on southern African flora.Published: Vols 14–19 (earlier volumes published as supplementary volumes to the Journal of South African Botany).
