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  Currently, based on unpublished treatment by H. H. Bloom, most collections reported earlier editions of this Checklist under the names Schistidium agassizii, S. apocarpum and S. rivulare, may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