Schistidium  Brid. [GRIMMIACEAE] 

         The understanding of this genus in the Interior Highlands is in a state of flux.  Currently, based on unpublished treatment by H. H. Blom, most collections reported earlier editions of this Checklist under the names of Schistidium agassizii, S. apocarpum and S. rivulare, may be placed in two taxa, Schistidium apocarpum subsp. canadense (Dupr.) H. H. Blom ex B. H. Allen & Pursell and Schistidium viridie H. H. Blom. The following treatment of Schistidium for the Interior Highlands of North America is based primarily on specimens deposited at the Missouri Botanical Garden (MO).
