FIGURE 7 in Taxonomy and evolutionary diversification of the Central European endemic Spergularia echinosperma (Caryophyllaceae)

FIGURE 7. Characters measured on the seeds (A) and surface papillae (B). The black curved line specifies the part of the seed circumference where the density of papillae was determined. The longitudinal border of this part is a plane halving the vector of maximal seed length and perpendicular to it (indicated by a dotted line). The character PapRat was computed by dividing the width of the papilla head by the width of the neck.
