Clasmatodon parvulus, var. rupestris, Sulliv. & Lesqx. op. cit. No. 246b.
Hab. Trunks and branches of trees in dry places: the variety on the base of trees, stones, &c, near the ground, affecting damp situations, Southern States.—Common.
The size of this species, and the form of its leaf, capsule, operculum, etc., are subject to variations, depending mainly on its location.
The var. rupestris appears to resemble very closely (if, indeed, it is not the same as) Anisodon tenuirostris, Bryol. Europ., found only in the Southern States, and of which we have seen no authentic specimens.
