Breidler (sub nom. » W. pulchella* in herb. S. 0. L., H. L., 

 V. F. B.). 

 Enligt ett meddelande af Dr. Hagen i Botaniska Notiser, 

 1897, p. 171, torde Pohlia lutescens afven mojligen vara tagen 

 i sodra Sverige; omojligt ar det ej, da den ar antraffad vid Lyck 

 i Preussen. Bland det rikhaltiga material, som statt till min 

 disposition fran Skandinavien af Pohlia palchella, har jag dock 

 ej patraffat en enda form, som skulle kunnat hiinforas till P. 

 lutescens.
