SPIKE-MOSS FAMILY

Dieter H. Wilken

Plants on soil, rocks, or other plants, cespitose, mat-like (± flat), or cushion-like (rounded)
Stems pendent to erect, short to widely spreading, rooting at base or in branch fork; branches intricately intertwined or not
Leaves many, simple, overlapping, appressed, small, ± scale-like, 1-veined, smooth to grooved on back, sessile to decurrent, generally 4-ranked; fertile leaves at same node of prostrate stems equal or not, if unequal, leaves below stem generally appressed, leaves above stem ascending to spreading
Cones generally terminal; leaves like those on sterile stems or not, generally strongly overlapping, triangular in X -section
Sporangia 1 per leaf axil, spheric to reniform; lower generally with (1–3)4 large, 3-ridged, yellow to orange spores; upper generally with many, small, generally pale-colored spores.
