FIGURE 1. Projection of variables on the factor plane (PC1 × PC2) scored for Calamagrostis emodensis var. breviseta and its allies. Abbreviations: AnthL, anther length (mm); AI, awn insertion (mm, measured as the length from the base of the lemma to the point of awn insertion); AI/LL, ratio: awn insertion to lemma length; AL, lemma awn length (mm); CHL, callus hair length (mm, measured as the length of the longest callus hairs); CHL/LL, ratio: callus hairs to lemma length; LGL, lower glume length (mm); LGW, lower glume width (mm); LGW/LGL, ratio: lower glume width to lower glume length; LigL, ligule length (mm); LL, lemma length (mm); LL/LGL, ratio: lemma to lower glume length; NCN, number of culm nodes; PL, palea length (mm); PL/LL, ratio: palea to lemma length; UGL, upper glume length (mm); UGL/LGL, ratio: upper glume to lower glume length; UGW, upper glume width (mm).
