“…The prevalent winds from the east could have allowed a steady stream of spores and propagules to be blown towards the Indian subcontinent, thereby establishing a high similarity of liverworts between Sri Lanka and Java. The liverwort genera Riccardia, Metzgeria, Plagiochila, Porella, Radula, Frullania, Lejeunea and Marchantia are globallybest represented in the tropics, including Sri Lanka (Schofield, 1985;Ruklani and Rubasinghe, 2013;Long and Rubasinghe, 2014). Among the hornworts Megaceros and Dendroceros are predominantly tropical and Sri Lanka has records of only one species under the genus Dendroceros (Schofield, 1985;Long and Rubasinghe, 2014).…”

Bryophytes (liverworts, mosses and hornworts) are the closest living relatives of the first group of plants that successfully colonized land. This small but well-established group of plants is unique among other land plants in having a dominant gametophyte phase in their life cycle and a single unbranched sporophyte that depends on the dominant gametophyte plant. Bryophytes occur throughout the world in all continents, occupying an assortment of habitats, especially in moist shady places. Many species have broad geographic ranges that may span two or more continents. Dispersal of bryophytes is brought about by spores, vegetative propagules or by unspecialized fragments of the gametophyte.The bryophyte flora of Sri Lanka remains relatively poorly researched. According to checklists available, the Island harbours 560 mosses, 327 liverworts and five hornworts. Most of the collecting has been in the southern half of the country, especially in the Central Highlands. Exact locality details are missing for most of these specimens. There is no documentation for moss or liverwort Flora of Sri Lanka. Lack of a thorough taxonomic foundation is a major impediment to study the biogeography of Sri Lankan bryophytes. O'Shea (2003) presented a summary of current knowledge of biogeography of Sri Lankan mosses. According to his statistical analysis based on existing records Sri Lankan mosses show strong relationships with India, Indochina, and Malaysia but a much lower affinity with Africa.Here we conducted a similar study for liverworts and hornworts using Kroeber's percentage of similarity, which suggests that Sri Lankan liverworts and hornworts show a considerable similarity with those of Java, Malaysia, Thailand, and India. However, more and wider systematic field explorations and taxonomic studies are needed to understand the biogeography of Sri Lankan bryophytes. To address this, field explorations and phylogenetic studies are being carried out, and the results will contribute to elucidate the biogeographic affinities of Sri Lanka's bryophyte flora.

“…Abewickrama and Jansen (1978b) also reported 569 species of mosses and high endemicity was noted (11%) among them. A recent study by Ruklani and Rubasinghe (2013) has added 12 new species of mosses.…”

Ethnomedicine evolved from the traditional use of plant parts for treating various ailments. Historically, most medical breakthroughs have arisen based on the plant sources showing potential for curing many diseases. Even so, the therapeutic power and scientific validation of their modes of action remains unexplored. Sri Lanka being a biodiversity hotspot due to its high endemism and diversity has inspired the search for ethnopharmacological values which may give rise to drug leads or to the discovery of new bioactive compounds. This brief review aims to highlight the global importance of the exploration of traditional medicinal plants, current status and the progress of the studies on Sri Lankan medicinal plants, and the necessity to discover the medicinal value of the Sri Lankan plants.

“…There are two species recorded in Sri Lanka which are C. cavernarum and C. smaragdinum Schiffn. Ex Keissl (Srivastava and Dixit, 1996;Ruklani and Rubasinghe, 2013;Long and Rubasinghe, 2014).-Cyathodium cavernarum is not recorded by although it is recorded by Long and Rubasinghe (2014). Srivastava and Dixit (1996) included records of C. cavernarum from a temple in Anuradhapura, Sri Lanka.…”

As part of a study initiated to trace the evolutionary relationships and biogeographic affinities of Sri Lankan complex thalloid liverworts, we here present the morphological diversity of Sri Lankan complex thalloid liverworts. This serves as the first detailed taxonomic study of the group in Sri Lanka. Specimens were collected from different geographical regions covering almost all topographic and climatic zones of the country. This study revealed 9 genera of complex thalloid liverworts in Sri Lanka. Based on our collections and identifications we prepared a generic key to Sri Lankan complex thalloid liverworts. Taxonomic descriptions were prepared for all identified genera.
