Eurhynchium angustirete (Broth.) Kop. (syn. E. zetterstedtii Storm.) is reported as new to the flora of the Netherlands; it was found near Steenwijk (prov. Overijsel). The author measured 33 capsules of E. striatum s. str. and 26 of E. angustirete from various parts of Europe. Those of E. striatum proved to be narrower (0,9—1,0(—1,1) mm) and usually less dark coloured than those of E. angustirete, measuring (0,9—) 1,0—1,4(—1,6) mm. No marked differences were found in the length of the urn.
