Nomenclature, Leucospermum sect. Hamata, L. sect. Secundifolia, Tetragonia ser. Echinatae


New infrageneric taxa are described in Leucospermum R.Br. (Proteaceae) and Tetragonia L. (Aizoaceae) to accommodate species that are currently unplaced in the respective generic classifications. Leucospermum section Hamata J.C.Manning is described to accommodate the relatively recently described L. hamatum Rourke and L. harpagonatum Rouke, and L. section Secundifolia J.C.Manning for L. secundifolium Rourke, which was unplaced following the transfer of the type of L. section Xericola Rourke to the genus Vexatorella Rourke. In Tetragonia L., T.
series Echinatae J.C.Manning & Klak is described for three species that were left
unplaced following their exclusion from subgenus Tetragonoides DC.. In addition, the three series T. series Chenopodinae, series Pedunculares and series Macranthae are incorrectly attributed to Fenzl and are shown to be combinations by Adamson of unranked taxa published by Fenzl. In Aizoon L., we replace the illegitimate name, A. procumbens (L.f.) Klak, with the new name A. flavescens Klak.
