DiCRANACEAE. Family. The Dicranum HE plants of this family vary in size from exceedingly minute to several inches in height. The leaves are broadly lanceolate to subulate, often sheathing at base, costate; leaf-cells square, or rectangular to linear, filled with chlorophyll above, more elongated and with little or no chlorophyll toward the base, often with special inflated cells at the basal angles. The calyptra is smooth, narrow, and cucullate. The capsules are an elongated setae, narrow, oval to cylindrical, frequently cernuous and curved; operculum usually long-beaked; peristome of i6 teeth which are cleft half-way to the base or further into two lanceolate or subulate divisions, usually of a reddish color, transversely barred.* There are a few cleistocarpous species with capsules rounded and immersed or elongated and exserted. The leaf character and the peristome when present will usually indicate the family to one who is at all familiar with it. The plants of this family are inhabitants of soil and rocks, rarely growing on trees, frequently on decaying wood. *For an illustration of a Dicranum peristome and a description of its workings see p.
