Abstract
Summary: There are three approaches to the problem of distinguishing the pollen of Betula nana. Grain morphology is not considered a reliable criterion. Size measurements alone serve to distinguish B. nana pollen from B. tortuosa, whilst the grain diameter: pore depth ratio distinguishes B. nana from B. pubescens. Reliable separation of B. nana pollen from tree birch pollen requires both these parameters.This publication has 9 references indexed in Scilit:
