Sachin Patil*, Shrirang Yadav and Meena Dongare: Tectaria fuscipes (Tectariaceae, Pteridophyta), a New Record for Southern India

Department of Botany, Shivaji University, Kolhapur, Maharashtra, INDIA*Corresponding author: sach2010d@gmail.com

Summary: Tectaria fuscipes (Wall. ex Bedd.) C. Chr. (Tectariaceae) is reported for the first time from Castle Rock, Forest of Uttara Kannada district, Karnataka, southern India. Previous south Indian records referred to the rather similar species, Tectaria paradoxa. Synonymy, description, range and phytogeographical details of Tectaria fuscipes are given, and a key to the species of south India.

Indian pteridophytes have been studied by various pteridologists viz., Beddome (1884), Dixit (1984), Fraser-Jenkins (1997), Chandra (2000), Ghosh et. al. (2004) and Fraser-Jenkins (2008). It consists of approximately 1000 species of pteridophytes belonging to 35 families and 192 genera (Chandra 2000). Most of the pteridophyte diversity is observed in the Himalayas, Eastern and Western Ghats. The south Indian pteridophytes were studied by Blatter and d’Almedia (1922), Naiknaware (1984), Manickum and Irudayaraj (1992), Jadhav (2011), Patil (2012) and Mahamuni (2012).

The genus Tectaria (Tectariaceae) is distributed throughout India, where 22 species have been recorded, out of which four species were reported from south India (Fraser-Jenkins 2008). However, in order to assess the pteridophytic flora of Northern Western Ghats (India) authors collected Tectaria species having dimorphic fronds which did not match with known species from southern India. It is identified as T. fuscipes which has been recorded only from northeastern part of India. This species is therefore reported here for the first time from Southern India. A brief taxonomic description and a key to the south Indian species of Tectaria

are provided here for easy identification.

Authors are very much thankful to the Head, Department of Botany, Shivaji University, Kolhapur for providing the laboratory facilities. The identity of Tectaria fuscipes in south India was confirmed after consulting with Fraser-Jenkins.
