The Taxonomic Position and Lectotypification of Frullania diversitexta Steph. (Frullaniaceae, Marchantiophyta) and Its Synonyms, with Notes on the Placement of F. ignatovii Sofronova, Mamontov & Potemkin

On the diversity and distribution of the genus Frullania in Northern Holarctic

“…The recently described section Inflatae includes here three species, namely F. inflata, F. rappii, and F. sabaliana -endemics of North America. There are also two new undescribed species of this section, first of which is still known only in Texas, while the second in Arizona and Baja California [14]. Section Pluricarinatae includes here three species -F. cobrensis, F. cuencensis, and F. mexicana.…”

“…Most representatives of another section, Australes, are distributed in East and Southeast Asia, Australasia, Africa, and South America, while only one of them, F. parvistipula, has been found in the Northern Holarctic, that is in Baikal Siberia (Russia) and Arizona (the U.S.A.) [20]. The monospecific section Diversitextae includes F. diversitexta, which is distributed in Japan, the Russian Far East, Republic of Korea, and China [13]. This species reveals close molecular and morphological affinity to another monospecific section of subgenus Trachycolea, namely Planae.…”
