Plagiopus Bridel, 1826.

Only one species of Plagiopus is found in the world, and that species has not yet been found in California. Its occurrence in nearby areas to the north suggests that it may be encountered here. It is a plant very similar to Bartramia pomiformis in possessing very narrowly subulate, strongly crispate and dentate to serrate leaf margins. The leaves differ from B. pomiformis in being tristichous and epapillose but with cuticular streaks resembling papillae running the length of the leaf. It should be looked for in moist rock crevices at medium elevations in the extreme northwestern part of the state.
