ANALYSIS OF GENERA.


                           SECT. I. ACROCARPI.

           Fr. terminal (or in a few instances cladocarpous).


              DIVISION A. Capsule without a deciduous lid.

                    _a._ caps. bursting irregularly.

 ARCHIDIUM (3). Perennial; caps. _globular_, _sessile_;
 calyptra thin and membranous, irregularly torn in the middle;
 _spores large_; infl. monoicous; barren fl. gemmiform,
 two-leaved or naked in axils of perichætial leaves.            PAGE 26.

 PHASCUM (4). _Annual._ Caps. ovate or roundish, very shortly
 _pedicillate_; calyptra campanulate; spores _small_, roughish;
 infl. monoicous; barren fl. gemmiform either at base of plant,
 or axillary, rarely terminal and discoid.                           26.

                     _b._ caps. bursting regularly.

 ANDREÆA (1). Caps. oval erect, opening by four _longitudinal
 slits_, sessile on a stalked vaginula; calyptra mitriform,
 thin; spores small, at first clustered together in fours:
 perennial.                                                          21.


                DIVISION B. Capsule with a deciduous lid.

                           I. PERISTOME NONE.

                _a._ caps. sessile on a stalked vaginula.

 SPHAGNUM (2). Perennial, aquatic; caps. globular, sessile on
 the turbinate fleshy stalked vaginula; lid flattish, calyptra
 surrounding the ripe caps., ruptured near the middle; spores
 as in _Andreæa_. Infl. monoicous or dioicous.                       23.

                _b._ caps. pedicillate; vaginula sessile.

   α. caps. cylindrical; lid with a straight beak; calyptra mitriform.

 ENCALYPTA (29) (In part). Caps. erect, regular, oblong or
 ovate-lanceolate, smooth or striate, lid conical with a
 longish almost filiform beak; calyptra very large, covering
 the capsule, fringed at base (peris. when present of 16 teeth,
 inner of 16 alternating erect cilia). Infl. monoicous or
 dioicous; barren fl. gemmiform, axillary or terminal.               74.

      β. caps. oval, lid with an oblique beak; calyptra dimidiate.

 GYMNOSTOMUM (5). Perennial; leaves of close firm texture, with
 small dense areolæ; barren fl. gemmiform, in monoicous species
 placed near the base of perichætium.                                31.

 POTTIA (21). Annual or biennial; l. rather succulent, with lax
 quadrate or rectangular areolæ, the lower ones enlarged. Infl.
 monoicous; barren fl. near the fertile, naked, or gemmiform
 with three leaves.                                                  55.

           γ. caps. roundish-pyriform; lid obliquely rostrate.

 STYLOSTEGIUM. (12). Perennial; caps. on a very short pedicel;
 calyptra small, cucullate, scarcely covering the lid; l.
 channelled, secund. Infl. monoicous; barren fl. gemmiform.          38.

 ANODUS (11). Annual or biennial; caps. pedicillate; columella
 free; l. setaceous, erect.                                          38.
