Polytrichum juniperinum - hairy cap moss

Family: Polytrichaceae

Polytrichum juniperinum has tall, erect stems bearing stiff, sharply pointed leaves with margins without teeth that are folded inwards so that opposing margins almost touch. Leaf structure is typical for the family, being many cells thick and having closely spaced lamellae running down almost the length of the upper leaf surface. Each lamella is one cell in thickness and 6-8 cells in height. The capsule covering (calyptra) is hairy and the capsule is box-shaped and almost square in cross section. 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 open sites from sea-level to subalpine areas.
