Genus name honouring J.E. Pohl, a German physician. Species name referring to last year's growth, the significance of which is not clear.
Clusters of gemmae are abundant and pale green, especially from autumn until spring; sporophytes are relatively frequent, red-brown when mature in late spring.
When bearing gemmae, these quickly identify P. annotina. The sporangia lack any hint of glossiness, a feature of the genus. The widely spaced marginal teeth also characterize the genus.
Loose, glossy, pale green to yellow-green turfs with reddish stems, at least in lower parts.
Many other species of Pohlia resemble P. annotina, and gemmae are frequently needed to distinguish them. Gemmae differ in colour and form among the species but need microscopic examination for discrimination. From Bryum, the toothed leaves and nonglossy sporangia are usually enough to separate these genera.
