Diskussion:Digitalis purpurea

Poland: spheroid, slightly triangular, oblate (PoFormI approximately 0.85), microreticulate to microrugulate. Small polar field (PolFeldI about 0:22). Aperturmembranes are not ornamented. According to Beug predominantly prolate, but found only slightly oblate PK (such as information in PalDat).

Verhältnis des polaren zum aequatorialen Pollenkorndurchmesser: Peroblat < 0.5; Oblat 0.5 - 0.75; Sphäroid 0.75 - 1.33; Prolat 1.33 - 2.0; Perprolat > 2.0.

Polarfeldindex: Polarer Pollenkorndurchmesser dividiert durch den aequatorialen Pollenkorndurchmesser (auch P/E-Ratio). Klein < 0.25; Mittelgross 0.25 - 0.5; Gross >0.5 - 0.74; Sehr gross > 0.75.
