“…Together with the Western Ghats of India, Sri Lanka forms a strong biodiversity hot spot in the world (Ashton et al 1997;Gunawardene et al 2007;Gunatilleke et al 2008;Rubasinghe and Long 2014). According to Senaratna (2001), the island harbours over 4100 native flowering plant species, out of which 30% are endemic to the country, and this includes ~ 70% of evergreen trees, 40% of lianas and 11% of mosses (O'Shea 2003;Gunawardene et al 2007;Rubasinghe and Long 2014;Ruklani et al 2016).…”

“…These results corroborates with those made by Tixier based on a collection made by himself in 1975 (Tixier 1975). All floristic analysis to-date are based on these past collections which had been in the southern half in the wet zone of the country (Rubasinghe and Long 2014;Ruklani et al 2016;Rubasinghe and Ruklani 2017). Many localities including natural forests and climatic and topographic zones remain under-explored for bryophtyes.…”

“…Sri Lanka encompassing a land area of about 65,610 km 2 is a tropical island in the Indian Ocean (7.8731° N, 80.7718° E), near the southwestern tip of India sharing the same continental shelf (Myers 1990;Meegaskumbura et al 2002;Bossuyt et al 2004;Daskon and Binns 2010;Ruklani et al 2016). Despite its small size, the island has a varied climate and topography.…”

Sri Lanka is a tropical island and lies in the Indian Ocean, near the southwestern tip of India sharing the same continental shelf. The island has a highly varied climate and topography, spanning from coastal region and lowlands with a tropical climate to central highlands with a cool temperate climate. Sri Lanka harbours a rich diversity of bryophytes. The aim of this study was to trace the species richness patterns and phytogeographic affinites of Sri Lankan thalloid liverworts and hornworts. The analysis is based on comprehensive field excursions carried out throughout the island covering all possible geographic localities. Distribution patterns were deduced for each taxon reported and phytogeographic affinities were traced on the basis of its present worldwide distribution. Their distribution patterns were compared with the floristic regions recognized for flowering plants of Sri Lanka. A variation in the species diversity and pattern of aggregation of species in different climatic and topographic zones was observed. Central Highlands in the wet and intermediate zones, represented the center of diversity of almost all reported taxa. Thalloid liverworts and hornworts are distributed in all floristic regions recognized for angiosperms, except in the coastal, marine and dry zone floristic regions. Zones of highest taxonomic diversity or "hotspots", have been inferred for taxa encountered in the island. Seventy five percent of all thalloid liverworts and hornworts reported from Sri Lanka are shared with the Western Ghats of India and 90% of taxa are shared with mainland India.

“…Sri Lanka is a tropical island with a high diversity of bryophytes, and harbours 327 liverworts, 561 mosses and 07 hornworts species (Abeywickrama and Jansen, 1978a;Abeywickrama and Jansen, 1978b;Abeywickrama and Jansen, 1960;Long and Rubasinghe, 2014;Mitten, 1859;O'Shea, 2002;O'Shea, 2003;Ruklani et al, 2016;Tixier, 1975;Tixier, 1983). Taxonomic studies on Sri Lankan bryophytes initiated only recently and therefore, apart from the lists of taxa, taxonomic descriptions, identification keys, phenological data or details of distribution patterns remain poorly understood.…”

Sri Lanka harbors a rich diversity of mosses (Phylum Bryophyta) with 561 species, 185 genera and 55 families. According to the checklist of mosses of Sri Lanka by O'Shea (2002), Polytrichaceae Schwägr. represents one of the most species-rich families comprising of two genera (Atrichum and Pogonatum) with 12 species. Available details on species and genera of the family are limited to mere literature based lists; no taxonomic keys, descriptions or monographs for therecorded species are available. The present study was carried out to investigate the species diversity and prepare a taxonomic treatment of the Family Polytrichaceae in Sri Lanka. Polytrichaceae is unique among other moss families by the formation of an epiphragm from the columella, presence of photosynthetic lamellae on upper leaf surface and multicellular peristome appearing single with 32 to 64 teeth. Specimens were collected from all possible geographic localities including; NuwaraEliya,
