Variety crenulatum is characterized by its oblong to oblong-lanceolate leaves with apiculate, broadly obtuse apices; the margins in almost all leaves are crenulate near the apex, and the seta is short. The exostome is papillose-striate as opposed to papillose. There are eight endostome segments and the capsule is strangulate when old.
