An excellent species, and a fine addition to our flora, remarkable for the
very short slender seta, which is often curved and flexuose.

The Marquis Bottini, in the paper quoted, has exhausted the subject of
the various forms of this species, and shown conclusively that F . Langei,
which is the British form, must be retained under F . serrulatus, having also
terminal setæ, and differing only by its papillose leaves with a colored margin
of about 4 rows of cells, but which is variable in tint and extent. Pie also
regards F . folyphyllus as a variety, a view with which at present we do not
coincide.

Fissidens adiantoides M i t t , in Journ. Linn. soc. Bot. xxi, 559 (1885).
Although Mitten refers this species to F . adiantoides of Hedwig, I look upon
that name as already occupied by the plant of Linnæus, certainly the same
as that usually so called ; and although Hedwig’s figure does look more like the
present plant, I do not think it conclusive, for F . adiantoides (L.) is usually
dioicous. Dr. Spruce finds a tall form with distant narrow, slightly crisped
leaves, growing on grassy hillocks under shade of Rosa spinosissima at Coney’s-
thorpe, which is identical with one found in Bhotan by Wallich. The
species is widely distributed throughout the whole northern hemisphere.
Var. /?. brevifolius Lindb.
Leaves dense, about half the length of those in the typical form, the
serratures less distinct or almost obsolete, the pale border narrower.
