Key Words: Pteridophytes – Distribution – Diversity – Tirumala Hills
Tiruumala is located near the holy city of Tirupati in Chittoor District of Andhra Pradesh State, South India. The geographical coordinates at which it is situated is between latitude 13° and 14° North and longitude 17° East. The Tirumala Hill is 3200 feet above sea level, and is about 10.33 sq miles in area. It comprises seven hills which are said to represent the seven hoods of Adisesha, thus earning the name, Seshachalam.
Pteridophytes are well known for their beauty, elegance and infinite variety. These are non-seed vascular plants which reproduce through spores. Their life cycle includes two chlorophyllous, autotrophic, independent phases namely dominant sporophyte and short lived gametophyte called prothallus. They show transition from simple microphylls to complex macrophylls called fronds. They show wide range of diversity in habitat, morphology, anatomical reproductive structures etc..The present study reveals the distribution and diversity of pteridophytes in different parts of Tirumala Hills. Materials and Methods
Various field visits were organized during 2009-2010 to different parts of Tirumala Hills along with expert Pteridologists. The various species were photographed, collected and preserved in the form of herbarium-specimens. The herbarium specimens are deposited with the Department of Botany, N.B.K.R Medicinal Plant Research centre, Vidyanagar, Nellore District, Andhra Pradesh.
