H a b .— On rocks in subalpine districts.
Scotland (Dickson). Anglesea (Davies). Near Derry and Colin Glen (Scott 1802).
This species is very variable in size and tint, and several forms may be
found growing together in one tuft.

Readily known from A . nibnm by turning pale vinous red in drying ;
the male infl. is so conspicuous, that when growing alone it has the aspect
of a Phascum in fruit.

Anisothecium Grevillei L in d b . o p . c . 26 (1878).
Dioicous or autoicous ? densely cssspitulose, glossy yellowish green ;
leaves from a wide sheathing base, suddenly narrowed into a flexuose-
patulous subula, margin subundulate, quite entire or with 2 or 3
irregular serratures at a p e x ; basal cells elongated, upper ob lon g;
perich. bracts more sheathing. Capsule cernuous, on a purple seta,
obovate or oval, subgibbous, fa intly striated, solid, exannulate, with a
short tumid or obsoletely strumose neck ; lid with a subulate beak.
Male infl. gemmiform, terminal ; b ra c ts convolute, lanceolate-subulate.
H a b .— Damp clay soil in mountain districts ; rare. Fr. 9.
Old road in Gen Tilt, Blair Atholl [Hookey and GreviUe 1823) ! ! Glenshee (Fergusson).
Both Wilson and Schimper describe this moss as monoicous, but De
Notaris (Epilogo p. 641) as dioicous, observing that he could detect no male
infl. on fruiting plants, and this is also my experience both with original
specimens from Glen Tilt, and Finland ones from Lindberg. The latter also
have the lid conical and only slightly rostellate, so that it is evident this part
varies considerably, as it is usually subulate and decurved.
4. ANISOTHECIUM CRISPUM (Schreb.) Lindb.
Dioicous ; leaves from a dilated base, narrowly lanceolate, irregularly
d enticulate a t point. Capsule ovate-oblong, cernuous, not s tria te ; lid
large, rostrate. (T. X V I , E.)
