Family of mosses
Polytrichaceae
is a common family of
mosses
. Members of this family tend to be larger than other mosses with a thickened central stem and a
rhizome
. The leaves have a midrib that bears
photosynthetic
lamellae
on the upper surface. Species in this group are
dioicous
. Another characteristic that identifies them is that they have from 32 to 64
peristome
teeth in their
sporangium
.
