The most important macromorphological and anatomical characters of fescues A, B, I a cross-section with three well-defined ribs C, D, G, H a cross-section with only midrib or also two lateral ribs weakly defined. Shape of the cross-section leaf blades: A 4 angular B, C, H obovate A, C, D diagram of the leaf blades’ anatomical structure of Festuca (designed by E.B. Alexeev): а) diameter, b/c) ratio b/c, 1) lateral sclerenchyma strand, 2) lateral ribs, 3) keel sclerenchyma strand, 4) middle rib, 5) vascular bundles, 6) continuous sclerenchyma layer C lateral sclerenchyma strands similar middle strand H lateral sclerenchyma strands less, than middle strand F flower: a) awn, b) lemma E panicle with 1–2 spikelets on lower branches, contacted J panicle with more than 2 spikelets on lower branches, open K grouped shoots (2–3 shoots surrounded by old sheaths) L single shoots: 1) flowering shoot, 2) vegetative shoot (AKA tillers).
