Stipellula parviflora var. hoggarensis F. M. Vazquez

Stipellula parviflora var. hoggarensis (Chter & Martinovsky) F.M.Vázquez (Figure 66 (2)). Lemma dorsal surface: Characterised by rectangular or quadrangular long cells of (6–)8–24(–34) × 10–14(–16) µm, smooth to undulated walls up to 2 µm thick, linear distribution. Short cells: main Silica cells of (9–)12–18(–22) × 11– 16(–21) µm, circular to ovoid, occasionally elongated up to 28 µm wide, frequently solitary, occasionally in pairs or threes with cork cells, between long cells, density 54–66(–71) silica cells/100 µm 2; Cork cells (2–)5–9(–11) × 12–16(– 18) µm, fusiform to reniform, sporadic, in all cases with a silica cell. Spines and hairs: Hooks not studied; Prickles not studied; Macro-hairs 280–600(–700) µm long, circular base 10–16 µm, irregularly distributed across entire surface. Lemma apical surface: Characterised by similar long cell morphology, wall characteristics and distribution, length to 75 µm. Short cells: Silica cells equal in size, morphology and distribution, low density up to 34 silica cells/100 µm 2; Cork cells of equal size, morphology, distribution and density. Spines and hairs: Hooks circular to ovoid base (16–)18–26(–28) × 7–9(–10) µm high, regularly distributed in rows, in pairs with silica cells, more frequently solitary, density 6–12 hooks/100 µm 2; Longer prickles circular to ovoid base up to 27 µm, and up to 46 µm long, solitary, distal end of the apex distributed with angulated prickles of lineal base 15–18(–22) × 4–6(–8) µm in the margin; density 10–18 prickles/100 µm 2; Macro-hairs equal size, morphology and distribution, more frequent at distal part of lemma apex, at the apex some Macro-hairs reach 150 µm. Material studied: Algeria: Hoggar, montis Asekrem, 2600–2700 m.a.s.l., 19-III-1928, R. Maire (nº1330), MPU196599.
