Vazquez 2006 [136,498,1971,1999] Liliopsida Poaceae Stipa Plantae Poales 98 99 Tracheophyta species almeriensis  Lemma apical surface: Characterised by long cells similar to those of the dorsal area, slightly longer up to 100 µm and up to 11 µm thick, sinuous wall. Short cells: Silica cells of 7–12 × 4–7 µm, similar distribution to those of dorsal part, but ovate to oblong morphology; Cork cells (2–)3–6 × 5–10 µm, oblong to sub-reniform (fewer), more frequent in the dorsal area. Spines and hairs: Hooks unpointed, ovate base 7–12(–14) × 5–9 µm, lower density than in dorsal area 6–10 hooks/100 µm 2; Prickles absent; Macro-hairs of obovate to circular base, located at margin leading up to apex. Awn base surface: Characterised by long cells of acute to oblique apex up to 290 µm in twisted, flat and angled parts. Short cells absent. Spines and hairs: Hooks absent; Prickles absent; Macro-hairs absent. Stomata paracytic (Parallel-sided subsidiary cells type), of linear distribution in flat parts and in groove between twists, density 40–80(– 100) stomata/ 1 cm 2.  Material studied: Spain: Granada, Albuñuelas, sierra de Albuñuelas, 1356 msnm,  4-VI-2022,  L .   Concepción, D. M. &  F. M .  Vázquez HSS80853.
