6. L. Schimperi, Lesq. Plants subcespitose, nearly
simple, short, yellowish green : leaves open, flexuous or falcate-
secund, oblong at base, abruptly and narrowly long-subulate,
denticulate at the apex only, nearly filled in the upper part by
the costa; perichsetial leaves sheathing at base, the inner tubulose,
long-subulate : flowers gemmiforrn, narrow, axillary : capsule
oblong, erect, cylindrical, robust, yellowish brown, with a
shorter thick pedicel ; lid longer than iu the preceding species,
dark red, blunt at the apex ; teeth attached to a large orange
fugacious basilar membrane, slender, pale yellow, linear, irregularly
divided, the segments broad, trabeculate (not articulate),
lacerate or perforated ; annulus simple : spores very large. —

This species has tlie aspect of the last, but is easily recognized by its
greenisii color, the shorter broader solid capsule on a shorter thick pedicel,
the longer dark red operculum, the much longer leaves, larger basilar
areolation, and especially the peculiar characters of the peristome.
7. L. g lau c e sc en s, Hampe, 1. c. Plants cespitose, soft,
glaucous ; stems dichotomous or fastigiate : lower leaves very
small, distant, lanceolate, the upper tufted, lanceolate at base,
linear-subulate above, distantly serrate toward the apex ; costa
percurrent ; areolation distinct ; male and female flowers
gemmiforrn, terminal : capsule subcylindrical, thin ; lid narrowly
conical ; teeth attached to a very short basilar membrane,
the segments of various length, articulate, papillose,
purple. — Trichostomum glaucescens, Hedw. Muse. Frond, iii.

Plants cespitose or pulvinate. Leaves gradually lengthening
from the base of the stem upward ; areolation minute, chlorophyllose
in the upper part, diaphanous in the lower. Teeth of
the peristome divided to the base into two equal semiterete
very papillose segments, either entire or sometimes irregularly
divided or connate. Flowers dioecious.

open from an erect base, soft, linear-lanceolate, obtuse, carinate
concave, reflexed on the borders; costa stout, vanishing
below the apex ; perichætial leaves longer, more obtuse : capsule
ovate-oblong, on a thick red often flexuous pedicel; lid
obliquely rostrate, variable in length : teeth unequal, the segments

truncate, subpyriform ; lid large at base, obliquely long-rostrate ;
teeth split nearly to the base into nearly equal filiform segments
; annulus large, compound, easily detached.
