Cyperus rupestris – Cynodon dactylon Community 1.1 Ledebouria luteola – Digitaria eriantha Sub-community 1.2 Berkheya onopordifolia – Cynodon dactylon Sub-community 2. Setaria sphacelata – Acacia karroo Community 3. Diospyros lycioides – Rhus pyroides Community 3.1 Salsola glabrescens – Cynodon hirsutus Sub-community 3.2 Sphaeralcea bonariensis – Eragrostis curvula Sub- community 3.2.1 Setaria verticillata Variant 3.2.2 Phyla nodiflora Variant 3.2.3 Asparagus laricinusVariant 4.
