Ecology: Open montane to páramo and puna; on soil. Elevation: 1230-3900 m (Ecuador: 3080 m, Peru: 3900 m, Bolivia: 1230-3600 m). Distribution: Ecuador to Argentina and Chile, circum-subantarcitc (including Australia, New Zealand).
Bryum clavatum, as discussed and illustrated by Ochi (1970), is distinguished by the oblong, concave leaves, broadly acute to somewhat rounded apex, entire or nearly so margins, rather strong costa that is percurrent to short excurrent, firm-walled laminal cells, 2-4 rows of narrow cells forming a border from the base to midleaf. Other than the few collections cited, very little is known about this taxon in the Andes.
Specimens: BOLIVIA. La Paz: Jay s.n. (NY), Williams 1900 (H, JE, NY).
