Autoicous and syn o ico u s ; cæ sp ito s e , pale yellow-green, more or
less branched. L ow e r leaves remote, b ro adly lanceolate, upper larger
crowded, concave, broadly elongato-lanc. acuminate, acute, serrate at
ape.x ; nerve reddish, vanishing in the point or slightly e x cu r ren t;
margin plane, cells lax, thin pellucid and elongated at base, upper
hexagonal, minutely papillose, marginal usually smooth ; perich.
bra cts larger and more acuminated. Caps, on a ta ll red seta, e re c t,
obovate and oblong, pachydermous, pale olive brown, finally ferruginous
and tru n cate ; ca l. smooth, pale brown, with a b lack -point ; lid from a
plano-convex base, longly and obliquely rostrate, when ripe raised on
the atta ched columella ; peristome none. Male on a short la teral
branch, bracts three, resembling the leaves, ra rely synoicous.
H ab.— Moist gravelly banks by the sea and mouths of rivers ; not uncommon.
Fr. 4— 5.
Variable in size, in the length of the seta, capsule and lid, the serration
also sometimes becomes obsolete, and the nerve may vanish below the point,
at the point, or form an excurrent mucro ; it is therefore difficult to
define any distinct varieties.
4. POTTIA TRUNCATULA (L.) Lindh.
Autoicous ; la xly cæspitose. L e a v e s obovate-oblong, acuminate,
mucronate with the excurrent nerve ; ce lls above hexagonal, ch lo ro phyllose,
smooth. Caps, obovate-spherical, deoperculate subhemi-
spherical ; lid ros trate, ca l. smooth. (T. X X V U I , E.)

A utoicous ; cæspitose or densely gregarious, simple or dichotomous,
deep green. L e a v e s obovate-oblong and subspathulate, shortly a cu minate,
mucronate with the excurrent nerve, pa tent and patulous,
w idely concave at base, carinate toward apex, plane at margin, soft,
smooth ; cells at base hexagono-rectang. above large rounded-hexagonal,
chlorophyllose. S e ta short, reddish ; ca.ps. subglobose-turbinate, constricted
below th e mouth, when empty truncate and nearly hemispherical,
fuscous, leptodermous, exannulate ; ca l. smooth ; lid plano-convex, with
a longer or shorter oblique beak, falling with the columella atta ched ;
spores n early smooth, brown.
Male infl. gemmiform, in axils o f upper leaves, bracts 2— 3, ovate-
acuminate,-nerveless.
Hae.— Fallow ground in fields and gardens and on hedge-banks ; common.
Fr. 1— 3.
This common plant varies considerably in size and in the form of the
fruit at maturity and after the lid is cast off, but is easily recognised by the
bright green, large celled leaves, and wide mouthed capsule.
5. POTTIA INTERMEDIA [Turn.) Fuernr.
Resembling P . truncatula, but larger. Le a v e s oblong, apiculate,
margin revolute to above middle. Caps, obovate or subcylindric,
annulate. (T . X X V U I , F.)
