Notes.

Poa nemoralis  is a polymorphic species with two recognised patterns of variation and numerous transitional forms in the territory encompassed by Flora iberica. The first recognised variety, Poa nemoralis  var. nemoralis  [ Poa cinerea  Vill., Hist. Pl. Dauphiné 2: 126. 1787, type: "Il vient au même endroit que le précédent -Poa angustifólia-.”; P. debilis  Thuill., Fl. Env. Paris ed. 2: 43. 1799, type: "Habitat in pratis"; P. miliacea  DC. in Lam. & DC., Fl. France ed. 3, 3: 64. 1805, type: " .. par M. Ramond, qui l’a trouvée dans les Pyrénées; ..."; P. nemoralis var. montana  Gaudin, Alpina 3: 27. 1808, type: "In den Wäldern des Jura Ṩ. Bl. im Jun. un Jul."; P. nemoralis subsp. vulgaris  Gaudin, Agrost. Helv. 1: 179. 1811, nom. superfl.; P. nemoralis subsp. firmula  Gaudin, Agrost. Helv. 1: 181. 1811, type: "In plantici dumetis non rara"; P. nemoralis subsp. coarctata  Gaudin, Agrost. Helv. 1: 185. 1811, type: "In aridis apicisque, ad muros etiam alpinis hawd infrequens"; P. nemoralis var. miliacea  (DC.) Godr. in Gren. & Godr., Fl. France 3: 541. 1856; P. nemoralis var. eunemoralis  Hack. in Briq., Prodr. Fl. Corse 1: 141. 1910, nom. inval.], is widely distributed in the area covered by Flora iberica [And. Por.: BA DL TM. Spa.: Al Av B Bu Ca Cc Cs Cu Ge Gr Gu Hu J L Le Lo Lu M Ma Na Or O P S Sa Sg So SS T Te To V Va Vi Z Za]. This taxon includes plants that are usually green or sometimes glaucous, generally with smooth and flexible stems and with most leaves flat and flexible, linear or linear-lanceolate and erect or erect-patent. The other variety, Poa nemoralis  var. rigidula Mert. & W.D.J. Koch, Deutschl. Fl. 1: 617. 1823 [type: "Auf Wiesen, im Gebüsche der Triften, am Saume der Wälder”], is dispersed throughout the region [And. Port.: TM. Spa.: (A) (Ab) Al Av Bu Cc Gr Hu L M Na P S Sg Te Z] and includes plants that are usually glaucous, with rigid and often rough stems and usually convolute leaves that are setaceous, linear or linear-lanceolate, ± rigid and erect.
