41. P. ROSTELLATUM. Brid. St. ⅛–¼in., tufted; l. linear-lanceolate,
spreading obtuse, nerve excurrent, margin plane; caps. olive-brown ovoid
elliptical with a straight beak; pedicel equalling caps. in length: a
smaller plant than the last.

Dried beds of pools, &c. Autumn, Spring.


                         5. GYMNOSTOMUM. HEDW.


 SECT. I. Infl. dioicous, margin of l. reflexed or plane, not incurved.


  _a._ St. short, per. l. sheathing; caps. elliptic-oblong, narrow at
             mouth, lid conical, annulus large persistent.

42. G. TENUE. Schrad. St. tufted; l. lingulate, sub-erect, upper ones
longest entire, nerved nearly to apex; caps. pale brown, lid obtuse.

Sandstone rocks and walls. VII. VIII.


  _b._ St. taller, branched; per. l. slightly sheathing, caps. oval or
   ovoid, truncate; lid with a long beak, annulus narrow, persistent.

43. G. RUPESTRE. Schw. St. ½in. densely tufted, slender, dichotomous; l.
linear-lanceolate, spreading obtuse keeled, nerved nearly to apex;
capsule erect oval, lid flattish, suddenly rising to a longish scarcely
bent beak.

Wet alpine rocks. Autumn.

 var. β. _ramosissimum._ densely tufted, leaves shorter, capsule smaller
           on a shorter pedicel.

      γ. _stelligerum._ loosely tufted, l. fasciculate and
           stellato-patent at the ends of the branches,
           linear-lanceolate acute.

      δ. _compactum._ leaves fascicled, longer and more obtuse.


44. G. CURVIROSTRUM. Hedw. St. ½–1in. cæspitose branches fastigiate; l.
linear-lanceolate, spreading keeled, margins recurved, nerved nearly to
apex; caps. broadly ovoid, lid adhering to columella, conical battened,
with a long suddenly bent beak.

Moist sub-alpine rocks. Autumn.

 var. β. _pomiforme._ leaves narrow, caps. more spherical.

      γ. _microcarpon._ l. broader, erecto-patent, caps. smaller,
           roundish obovate.

      δ. _pallidisetum._ st. long slender, l. fascicled, caps. small
           obovate, with a shorter pedicel and beak.


    SECT. II. Infl. monoicous; margins of l. incurved or plane, not
                               reflexed.


_a._ Caps. contracted at mouth; sporangium adherent to columella forming
                             a closed sac.

45. G. SQUARROSUM. Wils. St. ¼in. loosely tufted, l. linear-lanceolate,
squarrose, distant, blunt, nerve running out into a mucro; caps.
elliptical, sometimes oblique and unequal; lid with a blunt beak.

Clay fields and banks. Autumn, Spring.


46. G. MICROSTOMUM. Hedw. St. ⅛ to ¼in. densely tufted; l.
linear-lanceolate, acute, upper ones longest, nerve excurrent; capsule
elliptical, sometimes oblique and gibbous, olive-brown, much contracted,
lid with a longish curved beak.

Fields, &c. Spring.

 var. β. _obliquum._ caps. oblong, oblique, lid sub-rostrate.
