Taxonomic and nomenclatural novelties in Syntrichia (Bryophyta: Pottiaceae), with reinstatement of an endemic continental Antarctic species

Nomenclatural novelties and notes in Penstemon (Plantaginaceae)

Seven nomenclatural novelties in Penstemon (Plantaginaceae) are proposed for taxa that will be included in the forthcoming treatment of the genus in the Flora of North America North of Mexico series. Three additional novelties are made for Mexican taxa outside the flora area. Penstemon xylus A. Nelson is determined to be the correct name for the species heretofore called P. tusharensis N. Holmg...

Nomenclatural novelties in the Postia caesia complex

Within the genus Postia, the P. caesia complex forms a distinctive morphological group. Based on recent molecular data, the current taxonomic status of the P. caesia complex is discussed and the nomenclature of the related taxa is revised as well. New combinations are: Postia subg. Cyanosporus, Postia africana, Postia amyloidea, Postia caesioflava, and Postia coeruleivirens.

Taxonomic novelties in Scapania
