Plagiochila squamulosa subsp. tamas-pocsii Sajitha, Manju & Rawat, a new subspecies of P. squamulosa Mitt. of sect. Vagae Lindenb., is described from the Nelliyampathy Hills in the Western Ghats of Peninsular India. This is the first Indian record of the species P. squamulosa from outside Africa and is supportive of the close relationship between the bryophyte floras of tropical Africa and southern India. The affinities of the new subspecies with P. peradenyensis Schiffn. and P. palangiensis S.C.Srivast., K.K.Rawat & P.K.Verma are also discussed. [ABSTRACT FROM AUTHOR]

The article explores the new records of national and regional bryophyte. These include the species of Anomobryum bavaricum, Barbula convoluta, and Bartramia strumosa which are distributed in various countries, such as Russia, Mexico, and the U.S., characters that distinguish the species of Brachymenium andersonii, Brachymenium morasicum, and Brachythecium salebrosum, as well as their classification.

The article offers information on national and regional bryophytes which involves plant species. It mentions that Brachythecium rutabulum is a bipolar species with some intermediate stations in tropical mountains in the Americas, East Africa and in the Hawaiian Islands in the Pacific Ocean. It states that Bucklandiella chlorocarpa is a rheophytic moss growing on rocks, often submerged, in stream beds and cascades with quickly flowing water.

The article offers information on the recording of new regional and national bryophyte species, and mentions the distribution of species in various countries. Topics discussed include Brotherella harveyana of the Sematophyllaceae family found in India; the moss species Bryum pseudotriquetrum found in Antartica; Bryum tenuisetum found in Hungary; and Frullania subarctica found in Japan.

The article discusses the status of the genus Rectolejeunea A.Evans bryophyte in Tamil Nadu, India. The genus Rectolejeunea is noted to have dark green in colour, with medullary cells and broad ventral keel. The identity of the genus is determined as Lejeunea aloba. The Indian species under genus Rectolejeunea is considered to fall under genus Lejeunea based on their characteristics like pycnolejeunoid subgynoecial innovation and presence of caducous leaves and basal.
