Distinguishing Features
Plagiochila semidecurrens is an uncommon plant of very wet habitats, where its horizontal stems are laden with drooping, roundly folded and very toothy leaves that are shiny when dry. The spine-like teeth are unique for the genus in the region on account of their number (many!) and length (up to 6 cells long).
Similar species
Instantly recognizable as a Plagiochila on account of its simple leaves with roundly-pleated bases alternating along an arching stem, P. semidecurrens is most likely to be mistaken for P. porelloides, which can occur in the same habitat. That species, however, has teeth that are shorter (1-3 cells long) in comparison to the 3-6 cells that make up the length of teeth in P. semidecurrens.
Habitat
Moist to wet mineral soil, rock outcrops, boulders, cliffs, streambanks, and tree trunks (esp. alder, cedar) in the lowland, montane, and subalpine zones
