Pohlia section Cacodon (Mielichhoferiaceae, Bryophyta) with axillary bulbils in the Iberian Peninsula

摘要

A taxonomic and descriptive study is presented of the propaguliferous species –with axillary bulbils– of section Cacodon of the genus Pohlia in the Iberian Peninsula. Among the nine species of this section present in the Iberian Peninsula, seven produce axillary propagula (bulbils). The propagulum morphology, seen to be the most relevant gametophyte identification character, is described. Data are provided on the habitat and distribution of the species in the Iberian Peninsula, where they are considered rare or very rare.
