Peristome, the fringe surrounding the mouth of the capsule upon removing the lid. This fringe may consist of a single row of processes, known as teeth, as in Fig. 7, or of a double row as in Fig. 27. In the latter case the entire fringe is still the peristome, but the term is also applied in a particular sense to the outer row; the outer row is often spoken of as the exostome (&), and the inner as the endostome (c). The inner row consists of as many projections as the outer, but al- ternating with them; these are known as processes or segments (c). Between the segments there are often one or more slender hair-like processes known as cilia. (Fig. 27, d; Fig. 11, c.) Fig. 27. Moss peristomes, viewed with a compound microscope, are among the most beautiful of natural objects. They are not composed of cells (except in the Polytri- chaceas and a few other small fam- lies), but of thickened cell-walls. Pinnate, having numerous equi- distant spreading branches on each side like a feather. (Fig. 28.) Pleurocarpous, having the sporo- phyte lateral on a short lateral special branch. (Fig. 29.) Pleurocarpous mosses can usually be recognized by the creeping habit. Plicate, folded in pleats or furrows; e. g., leaves of Camptothecium. (Fig. 30.) Plicae, folds of a plicate leaf. Plumose, feathery. Pluriseriate, many ranked; i. c, as applied to leaves arranged in several rows along the stem. Polygamous, with antheridia and archegonia disposed in.
