Abstract: Stipellula capensis (Thunb.) Röser & Hamasha (Figure 65 (1)). Lemma dorsal surface: Characterised by rectangular to quadrangular long cells of (7–)8–24(–31) × 12–14(–16) µm, smooth to undulated walls up to 1 µm thick, linear distribution. Short cells: main Silica cells 12–19(–22) × 14–20(–24) µm, circular to ovoid, frequently solitary, occasionally in pairs or threes with cork cells, between long cells, density 42–61(–64) silica cells/100 µm 2; Cork cells (2–)4–8(–9) × 12–18 µm, fusiform to reniform, sporadic, in all cases with silica cells. Spines and hairs: Hooks not studied; Prickles obovate to circular base (17–)22–29(–35) × 20–27(–29) µm, and up to 75 µm long, irregularly distributed between long cells, solitary, density <3 prickles/100 µm 2; Macro-hairs 600–1100(–1370) µm long, circular to obovate base 22–36(–43) × 22–29(–32) µm, irregularly distributed across entire surface, combined with Macro-hairs up to 210 µm long, and circular to obovate base 20–32(–38) × 21–27(–30) µm irregularly distributed between long cells. Lemma apical surface: Characterised by similar long cell morphology, wall characteristics and distribution, length to 42 µm. Short cells: Silica cells equal in size, morphology and distribution, lower density to 28 silica cells/100 µm 2; Cork cells of equal size, morphology, distribution and density. Spines and hairs: Hooks not studied; Prickles of equal size, morphology and distribution, denser up to> 4 prickles/100 µm 2; Macro-hairs of equal size, morphology and distribution, more frequent towards distal end of lemma apex.
