Tetraphis is a genus of two species of mosses (Bryophyta). Its name refers to its four large peristome teeth.

Reproduction

The sex of Tetraphis shoots can transform depending on the shoot density. When a colony is sparse female—gemmae-producing—shoots dominate. When the colony is sufficiently dense they transform into male shoots.[1]

This density-dependent sexual reproduction strategy is common in fish but Tetraphis is the first moss in which this has been documented.[1]
