Stipa maroccana H. Scholz ( Figure 62 (1)).

Lemma dorsal surface: Characterised by rectangular long cells of 14–37 × 12–21 µm in dorsal area and 30–55 × 10–20 µm at margins, smooth walls, 2–5 µm thick at margin and thicker, 3–6 µm in dorsal, linear distribution. Short cells: main Silica cells of 8–11 µm, circular to obovate, sporadic, more frequent at margin, in pairs or threes with a hook or occasionally with a cork cell, situated between long cells, never solitary; Cork cells 9–12 × 5–11 µm, circular to reniform, sporadic, always with a silica cell. Spines and hairs: Hooks circular base 10–22 × 5–7(–8) µm high, regularly distributed between long cells, in pairs or threes with silica, cork or additional hook cells, more frequently solitary, density 12–15 hooks/100 µm 2; Macro-hairs 300–480(–525) µm long, circular base 22–31 µm, regularly distributed in rows from mid-dorsal area to base of lemma.

Lemma apical surface: Characterised by long cells similar to those of the dorsal area, slightly shorter 18–38 × 10–12 µm. Short cells: Silica cells of equal size and morphology to the dorsal, more frequent; Cork cells of equal size and morphology to the dorsal, more frequent. Spines and hairs: Hooks equal in size and morphology to the dorsal, irregular distribution, denser than in dorsal area (16–21 hooks/100 µm 2); Prickles not studied; Macro-hairs circular to ovoid base 28–44 × (18–)21–30(–34) µm and 90–400(–420) µm long, distributed at middle and distal parts of apex. Material studied: Morocco: Serghin, 1920 m.a.s.l., 1-VI-2021, M . Chamboleyron , ECWP n.n.
