H a b .— 7. At the mouth and on the roof of an old copper mine
between Dolgelly and Tyn-y-Groes, Merionethshire, TF.II. Pearson,
April 1877. Rhaider Dhu, Tyn-y-Groes, G. A. Holt, July 1882.
Mouth of copper mine, near Pistyl Cain, Tyn-y-Groes, C. .T. Wild,
July 1882, Extremely rare.
Obs.— “ Ceph. Alacounii, Aust., comes near to it, but is of a
green colour, steins slender and much branched, leaves subimbricate,
sinus sometimes lunate, apices of lobes not nnguiculate, cells
subquadrate, stipules none. Ceph. divaricata (Sin.) certainly distinct,
flowers aorogenous ; leaves distinctly carinate, rarely more
than to the divided, exunguiculate, cells quadrate, reticulate
(not guttulate). I t differs essentially from C. divaricata in being
still more minute, in the deeply bifid leaves whose narrow segments
end in a clawlike apiculus, the guttulate areolation and
especially in the cladogenous inflorescence which brings it near
to C. Macounii.”—R. Spruce.

17. Cephalozia Jackii, Limpricht MSS.
Cephalozia .Taekii, Limpr., MSS. Spruce, On Cephalozia, p. 07 (1882).
Paroicous, cæspitose, eflagelliferous, small, size of Ceph.
divaricata, aero- and cladocarpous, pale green to reddish-green,
with the flowering apices often purplish. Stems short, fragile,
simqJe or with few brandies, prostrate, radiculose, ends ascending,
some branohes elongate, with minute leaves. Lower leaves, chiefly
of the sterile branches, distant, minute, cuneate, upper near the
? flowers imbricate, cuneate-quadrate or subrotund, all subcari-
nate, almost or even to the middle acute bilobed, segments ovate-
triangular, acute; cells verj' small to small, quadrate to subelongate,
4-, 5- and 6-sided, angles thickened, no trigones.
Stipules half the size of the leaves, lower ones linear or lanceolate,
upper ones ovate-lanceolate, rarely divided at the apex. Involucre
ovate-juliform. Bracts 3-5 pairs, larger than the leaves, ohlong-
orbioulate, concave, less deeply bilobed, more or less denticulate,
enclosing single antheridium, which is oval, the innermost bracts
highly connate, forming with the smaller bracteole (with which
both bracts are connate) a cuplike receptacle. Perianth twice as
long as the bracts, projecting above half its length beyond them,
oblong or ovate-oblong, obtusely 4-5-angled (very rarely trigonous),
composed of a single layer of cells, about 80 round, near the
middle, mouth scariose, truncate, repand, afterwards variously
divided. Capsule oblong.
Fruits March, April.
