Festuca viviparoidea Krajina ex Pavlick subsp. viviparoidea leaf cross section. Photos A–D by Martin Dubé. Scale bar: 500 µm. Leaf cross sections were obtained by cutting a &lt;1 mm long section between the first 1/3 and the middle of the basal leaf blades. Leaf cross section in F. brachyphylla subsp. brachyphylla (A) shows five variously defined ribs with only the midrib being delimited by deep grooves approximately reaching the vein level. Leaf cross section in F. hyperborea (C) usually shows even less welldefined ribs than F. brachyphylla subsp. brachyphylla (which is not the case here) but retains the same looking midrib. Compared to these two species, F. edlundiae (B) presents midrib grooves that are deeper and go beyond the vein level while the other lateral ribs are also consistently well-defined. In F. viviparoidea subsp. viviparoidea (D), the grooves are shallow with well-defined but still small ribs, giving that species unique anatomical facies among Festuca species in Canada (M Dubé personal observation). Ribs, identified by R letters, are the longitudinal bumps containing veins and are delimited by the contiguous grooves (however, some veins may not be included within the ribs)." pageId="24" pageNumber="205">12B</figureCitation>
