7 7 . PHILONOTIS, Brid.
Plants short, reclining at base, or long and erect, branching
by dichotomous innovations and by fasciculate branchlets verticillate
in fours at the floriferous apex, radieulose-tomentose.
Stem-leaves nearly equal, small for the size of the plants, erect
or a little inclined to one side, lanceolate, sharply serrate, papillose
on the angles of the areoles. Flowers monoecious and
dioecious, the male discoid in the dioecious plants. Capsule
long-pedicelled, cernuous, globose, striate. Lid small, oblique.
Inner peristome distinctly ciliate.
1. P. Muhlenbergii, Brid. Dioecious: plants loosely and
widely cespitose ; branches numerous, nearly simple, slender,
flexuous, with fasciculate branchlets : stem-leaves erect, subsecund
on the fruiting stems, lanceolate, acute, remotely cirrhate,
bright green ; costa thick, rusty, excurrent ; inner perichsetial
leaves much smaller, lanceolate, obtuse, tender, whitish,
strongly nerved : capsule globose, horizontal, very shortnecked,
ribbed; lid convex, aouminate or mucronate; segments
nearly as long as the teeth ; cilia 2, short, rudimentary. —

Var. ten e lla , Brid. Very small, densely cespitose; branchlets
5 to 10, unequal, secund or recurved, short and slender:
leaves short, lanceolate ; capsule globose-ohlong. — Bartramia
tenella, Muell. Syn. i. 481.
IIab. Springs in sandy hills and rocks; common in Oliio and Pennsylvania.
The variety is given in Rau & Hervey’s catalogue on Austin’s
autliority as from Florida. It is a West Indian and South American form.
Tlie characters indicated by Schwaegrichen and Mueller as separating
this species from P . Marchica, Brid., are not important. They consist
merely in the numerous long simple slender fasciculate branches, which
in P. Marchica are described as of various lengths, and in tlie inner perichætial
ieaves much smaller than the external ones, obtuse, strongly
nerved and whitish, while in P . Marchica they are as long or even longer.
2. P . Macounii. Plants very short and slender, loosely
cespitose, dirty or yellowish green : le.aves narrowly ovate-
lanceolate, long-acuminate, subulate, strongly serrate and flexuous
to the apex ; areolation quadrate, slightly papillose ;
branoh-leaves smaller, subfalcate ; perigonial leaves open-erect
or somewhat spreading, flexuous, lanceolate-acuminate from a
broadly oval much enlarged base ; perichætial leaves longer,
striate, subulate : capsule ovate or subglobose, greenish yellow,
cernuous, on a short thick blood-red pedicel ; lid conical, acute ;
segments a little shorter than the teeth ; cilia none.
Ha b . Vancouver Island (Macoun).
A slender delicate species related to P . Muhlenbergii, differing in the
longer-acuminate subulate leaves, with sliorter quadrate and less papillose
areolation, the perigonial leaves longer and acuminate, flexuous at the
point, etc. The form of the capsule is the same; the pedicel shorter,
thick, not geniculate at base.
3. P. fo n tan a , Brid. In wide more or less compact yellowish
green tufts; stems long, simple or dichotomous ; branchlets
verticillate, nearly equal : leaves often of two forms, either
small, ovate, obtusely pointed and appressed to the stems, or
larger, ovate-lanceolate, acute, erect and open or secund ; costa
excurrent into a short bristly point ; perichætial leaves linear-
lanceolate, plicate at the base, all serrate, papillose, glaucous-
green and opaque : male flowers broadly discoid ; inner perigonial
leaves ovate, lanceolate, spreading above the erect concave
base, blunt or subacute, densely serrate : capsule on a long
solid slightly flexuous pedicel, cernuous, ovate-globose, of thick
texture, striate, longer oblong and ribbed when old ; lid convex-
conical, acute; teeth purple, lanceolate; cilia two, as long as
the segments. — Bryol. Univ. ii. 18. Mnium fontanum, Linn.

Var. a lp in a , Brid. Plants short, densely foliate: leaves
shorter, ovate-lanceolate : capsule shorter pedicelled.
Var. fa lc a ta , Brid. Branches curved at top : leaves longer,
falcate ; costa thick, light brown.
Hab. On the borders of springs and rivulets, and on moist rocks; very
common. The first variety on high mountains, tlie second near springs
in valleys and on mountains; not common.
4. P. c a lc a re a , Schimp. Much like the last, differing in
its thicker wider bright green tufts and more robust stems ;
leaves larger, crowded, secund or falcate-secund, ovate-lanceolate,
those of the male branches often smaller and imbricate,
all loosely areolate with a stouter costa, the perigonium large
and open, and the involucral leaves long-lanceolate from an en
