Macrochloa gabesensis subsp. kelibiae F. M. Vazquez 2025

Macrochloa gabesensis subsp. kelibiae (Moraldo, Raffaelli & Ricceri) F.M. Vázquez (Figure 52 (2)). Lemma dorsal surface (including base): Characterised by long rectangular cells of (25–)50–120(–160) × (8–)10– 18(–20) µm, sinuous walls 5–9 µm thick, linear distribution. Short cells: Silica cells 12–21(–24) × 12–18(–21) µm, circular to ovoid in mid-dorsal area to elongate 21–37(–41) × 12–20(–22) µm at base, frequent, solitary or in pairs with cork, occasionally with hook cells, situated between long cells, density 7–10(–12) silica cells/100 µm 2; Cork cells not studied. Spines and hairs: Hooks ovoid base 20–28(–31) × 7–11(–12) µm high, irregularly distributed between long cells, frequently solitary, sporadically in pairs with silica cells, density <1 hooks/100 µm 2; Prickles ovoid base (20–)24–30(–34) × 19–25(–27) µm, and up to 20 µm long, irregularly distributed between long cells, solitary, density <1 prickle/100 µm 2; Macro-hairs 600–900(–1100) µm long, circular to obovate base 20–25(–27) × 18–20(–22) µm, irregularly distributed across entire surface, denser at base. Lemma apical surface: Characterised by long cells similar to those of the dorsal area. Short cells: Silica cells of equal size and morphology, distributed solitary, in pairs with cork but not with hook nor prickle cells, at lower density (4–) 5–7 silica cells/100 µm 2 than in dorsal area; Cork cells not studied. Spines and hairs: Hooks of equal size, morphology and frequently with silica cells, denser than in the dorsal area 2–4 hooks/100 µm 2; Prickles similar in base morphology and size than in dorsal area, but longer, up to 50 µm long, distributed at middle of the apex, density> 3 prickles/100 µm 2; Macro-hairs up to 950 µm long, circular to obovate base 18–24(–26) × 16–19(–20) µm, irregularly distributed, more frequent in middle of the apex. Stomata not studied. Material studied: Morocco: Bouarfa, 0631235/ 3609397, 1300 m.s.a.l., 11-IV-2017, M. Chambouleyron (ECWP s.n. (HSSrf 154)); Nzala, Irmil, 2020 m.a.s.l., 18-VI-2020, M.
