Grimmia anomala is extraordinary in the abundant multicellular globular gemmae produced at the leaf tips which
are deformed to accomadate them. In addition, it certainly appears as if the lamina cells are papillose,
but Hastings and Greven point out in Flora of North America volume 27 on page 248 that they are actually
longitudinal ridges on cell walls that resemble papillae.
Thanks to the University of Colorado Herbarium (COLO), Erin Tripp and Dina Clark for permitting us to photograph
this specimen.
