Although in external appearance, colour, and habit, this plant
looks ve ry different from Sph. squarrosum, and is so regarded by
most o f the leading bryologists, it will be found on careful examination
to present not a single point o f structural distinction, by which
they can be separated.
T h e plants are shorter and o f denser habit, but the perichætial
and stem leaves, although a little narrower, agree precisely in areolation
; the branch leaves indeed are ordinarily not squarrose, but
we constantly meet with stems which have the lower branches
more or less squarrose-leaved, while the upper retain their normal
direction, and if we examine growing tufts o f the plant, it is quite
common to find the central stems normal, while those at the circumference
o f the patch have all their branches squarrose-leaved.
T h e dioicous inflorescence and the elongated sterile termination to
the antheridial branches are the sole differential characters.
It also resembles the robust forms o f Sph. acutifolium, but has
stouter and more closely imbricated branch leaves, and the stem
leaves are quite distinct.
Professor Lindberg has pointed out that, like squarrosum, the
branch leaves have v e ry minute papillæ on the internal wall o f the
hyaline cells, where united to the chlorophyllose.

Monoicous ; slender, pale whitish green ; cuticular cells o f stem
in 2-3 strata. Stem leaves large, broadly obovate-spathulate ; the
margin in the rounded upper half laciniate-fimbriate ; border o f
narrow cells one-third the width o f leaf at base, disappearing halfway
up the leaf. Branch leaves ovato-lanceolate, the chlorophyllose
cells compressed, enclosed, but nearest upper surface o f leaf.
Perichætial bracts obovate-oblong, obtuse, emarginate. Male
amentula fusiform.

Monoicous ; in loose, pale whitish-green or glaucous-green tufts.
Stem v e ry slender, 6 - 14 in. long, pale green, with 2-3 layers o f
rectangular, porose, cuticular cells, those o f the peripheral layers not
coloured. Stem leaves large, erect, broadly obovate or obovato-
spathulate, the margin in the rounded upper half laciniate-fimbriate ;
hyaline cells o f the middle and upper part rhombic, with one
or more partitions, and without fibres or pores ; chlorophyllose
cells long, linear, forming a border which occupies one-third the
width o f base, but rapidly narrows and disappears half-way up the
margin.
Ramuli 3-4 in a fascicle, ve ry long, attenuated, two arcuate,
decurved, the others pendulous, filiform. Lower ramuline leaves
broadly ovato-lanceolate, upper elongate, lanceolate, acute, with a
narrow border ; hyaline cells with annular and spiral fibres, and a
row of large pores on each side ; chlorophyllose cells compressed,
enclosed by the hyaline, but nearest the upper surface o f leaf.
Capsules at first immersed in the large imbricated perichætium,
afterwards becoming moderately exserted ; lower bracts obovate
