Mosses -- Great Britain
431. H. (THUYIDIUM) DELICATULUM. L. St. elongate, erect or procumbent,
bipinnate; br. drooping, often rooting at apex; l. broadly cordate or
ovate-acuminate, sub-striate, papillose or muricate on back and keel,
nerved nearly to apex, which is finely serrulate; caps. sub-cylindrical
curved, cernuous, pale brown, lid large conical, not rostrate.
Limestone and chalk rocks, &c. VII. VIII.
432. H. (THUYIDIUM) TAMARISCINUM. Hedw. St. elongate, arched,
procumbent, interruptedly tri-pinnate; br. not rooting; st. l. cordate
acuminate, plicate; br. l. ovate, obtuse; all papillose at back, but not
so much so as last; serrulate near and nerved almost to apex; caps.
oblong-cylindrical, curved, cernuous, purplish red; lid large conical,
with a long beak.
Woods and banks, frequent. XI.
_Sub-genus_ II. PTYCHODIUM. Branches sub-pinnate; l. patent and secund,
often deeply sulcate, thinly nerved to apex; areolæ shortly linear,
quadrate at the angles; caps. cernuous, horizontal, ovate; per. teeth
dense and narrow, lamellose, cilia rudimentary.
433. H. (PTYCHODIUM) PLICATUM. Schl. St. creeping, tomentous; branches
ascending incurved; l. ovate, imbricate, pointed, margin recurved; per.
l. twice as large; caps. ovate-oblong, small, on a half-inch reddish
seta: dioicous.
Alpine rocks. S. IV. (?)
_Sub-genus_ III. CAMPTOTHECIUM. Stems trailing in part, sub-erect,
branched; l. silky, striate, thinly nerved, areolæ narrowly linear;
caps. cernuous, on a smooth or rough incurved seta; lid shortly rostrate
or conical; internal perist. with long cilia.
434. H. (CAMPTOTHECIUM) LUTESCENS. Dill. St. about 3in. irregularly
branched, sometimes pinnate; l. narrowly lanceolate, tapering to a long
point, entire, nerved nearly to apex; caps. oblong arcuate, on a rough
seta; lid conical, beaked: monoicous.
Rocks and woods (limestone and sandstone). IV.
435. H. (CAMPTOTHECIUM) NITENS. Dill. St. 2–4in. erect, almost pinnate,
radiculose; branches short spreading; l. erecto-patent, lanceolate, long
tapering, acute, not nerved to apex, entire, margin recurved; caps,
arcuate oblong, on a long smooth seta; lid conical: dioicous.
Bogs. E. S. IV. V.
_Sub-genus_ IV. BRACHYTHECIUM. Plants upright or prone, irregularly
branched; l. silky, patent or sub-secund, more or less decurrent, thinly
nerved, striate; areolæ narrowly hexagono-rhomboid, generally quadrate
at basal angles; caps. ovate, sub-globose, or oblong, often turgid, lid
