Plant diversity and endemism in Sri Lanka are quite high. Of 3,210 flowering plants belonging to 1,052 genera, 916 species and 18 genera are endemic. [3] All but one of Sri Lanka's more than 55 dipterocarp (Sinhalese "Hora") are found nowhere else in the world. Sri Lanka's amphibian diversity is only becoming known now.

The earliest notes on pteridophyte diversity of Sri Lanka dated back to 1887 with Baker's Handbook to the Fern Allies and then in 1892 with Beddome's Handbook to the Ferns of British India, Ceylon, and the Malay Peninsula. In 1947, Copeland adopted a taxonomical system to describe modern taxa of pteridophytes of Sri Lanka.
