Diskussion:Kirengeshoma palmata

Pollen: spheroid, triangular, round (PoFormI about 0.91), reticulate. Small polar field (PolFeldI approximately 0.18). Pores are not always well developed, round to oval, diameter about 6.5 (4.5-9.7) microns. Aperturmembranes are not ornamented. Erdtman referred to this species as 3-colpor(oid)ate.

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.
