List of pteridophytes of Sri Lanka
Invertebrates Flora Botanical gardens Civil societies Sri Lanka is a tropical island situated close to the southern tip of India.This makes it very complicated and difficult to summarize the exact number of species found within a certain region.These free sporing vascular plants show a remarkable life cycle with independent gametophyte and sporophyte generations.New leaves typically expand by the unrolling of a tight spiral, the phenomenon known as circinate vernation.In 1947, Copeland adopted a taxonomical system to describe modern taxa of pteridophytes of Sri Lanka.
