Status: Native
Synonyms:
Grimmia pellucida Kindberg
Grimmia prolifera Müller Hal. & Kindberg
Grimmia pseudotorquata Kindberg
Grimmia tortifolia Kindberg
Grimmia torquata should be fairly easy to recognize by virtue of its
curly-Q leaves when dry, but especially because of the abundant multicellular red-brown
globular, stalked gemmae present at the base of the abaxial (back) surfaces of some of the apical leaves
on stems. Many of the leaves have the stalks remaining after the gemmae have dispersed,
deceiving one into initially thinking that the stalks themselves represent the gemmae.
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp & Dina Clark for permitting us
to photograph this specimen.
