Status: Native
Synonyms:
Leskea rupestris Berggren
Leskeella nervosa (Bridel) Loeske var. sibirica (Arnell) Brotherus
Pseudoleskeella sibirica (Arnell) P. Wilson & Norris
Pseudoleskeella rupestris lacks the brood branchlets possessed by Pseudoleskeella nervosa and has a single
costa beyond midleaf unlike P. tectorum. It has an acuminate apex, no papillae, and leaves that are straight. This family and
genus have been confusing for quite some time and will continue to be revised.
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp & Dina Clark for loaning this specimen for photography.
