Identification notes
A very handsome robust moss of dry and exposed basic hard rock in the uplands. In the field, to bryologists who are unfamiliar with it, B. imberbis resembles Nogopterium gracile more than a species of Hedwigia, where it was formerly nested as H. integrifolia.
It always was the odd one out in Hedwigia, lacking hyaline leaf apices and growing in procumbent mats rather than as small tufts or patches.
