Atrichum androgynum


Atrichum androgynum has erect, unbranched stems. The linear-lanceolate leaves are thin and translucent, erect to spreading with a toothed margin and gradually narrow to a sharp tip. Unusual for this family, there are only 3-4 closely spaced lamellae running down almost the entire length of the upper leaf surface. Each lamella is one cell in thickness and 2-5 cells in height. Also unusual is the presence of teeth in oblique rows on the lower leaf surface. The  peristome is typical for the family, consisting of short teeth joined at their tips to a membrane covering the capsule mouth with small openings between the teeth.

Widespread in New Zealand in moist forest, clay banks and along stream banks in the shade.
