Hypnum extenuatum Brid.
species
Hypnum extenuatum
The epithet is from extenuata (Latin feminine superlative adjective from extenuo, to diminish, to make thin). The epithet refers to the extenuate/attenuate appearance of the branch tips (in contrast to those of Hypnum cupressiforme). However, Bridel described the leaf apices as piliform and “with filiform production”, so he may have considered “extenuatum” doubly appropriate (D. Meagher, pers. com. 11 Nov. 2015).
Type: Australia. Not seen.
