Its capsules are strongly curved and cer- nuous; they mature in autumn. H. IMPONENS Hedw., the Pinnate Hypnum, is a much more common moss in the lowlands and grows almost exclusively on rotten wood in moist shady places. It somewhat resembles the Plume Moss, but is prostrate, forming dense closely cohering mats. It is also darker green; the capsules are nearly erect and symmetric, and the pinnate branching stops short of the apex of the shoots, as is shown in the figure. A careful examination will show that there is a difference in the curvature of the leaves; in the Pinnate Hypnum the leaves curve towards the substratum at right angles to the plane of the stem, while in the Plume Moss they curve towards the branch next below on the stem. The capsules of the Pinnate Hypnum are produced much the more freely; they mature in winter, but persist in good condition for a long time. Hypnum curvifolium Hedw. is a much rarer moss that somewhat resembles H. imponens when sterile. It is more con- fined to the mountains, is larger, lighter colored, and has curved cernuous capsules that are very strongly furrowed when dry. The leaves when dry are so regularly arranged as to give a characteristic appearance like a carefully dressed braid of hair. H. PATIENTIAE Lindb. has furrowed capsules almost like those of the preceding and its general appearance is so similar that it.
