Abstract
Present study deals with the diversity, distribution and conservation status of the genus Athyrium Roth in different climatic regimes of Gujarat state. Five species of Athyrium viz., A. hohenackerianum T. Moore, A. falcatum Bedd., A. micropterum Fraser-Jenk., A. parasnathense (C.B.Clarke) Ching ex Mehra & Bir and A. schimperi subsp. biserrulatum (Christ) Fraser-Jenk., were collected form the Gujarat state, of which A. hohenackerianum T. Moore is documented earlier. Therefore, occurrence of A. falcatum, A. micropterum, A. parasnathense, and A. schimperi subsp. biserrulatum, stands as a new distribution records and reported for the first time from Gujarat state. A detailed taxonomic description, photo plates, morphological characters, distribution and comparison of species is provided here for their identification.
Highlights
The lady fern genus Athyrium Roth was originally described in 1800 [1] based on Athyrium filix–femina (L.) Roth
This species is luxuriously growing in the south Gujarat, a population of about 80-150 individuals were found and the area of occupancy (AOO) is 250 km2
A. solenopteris is reported from Girnar Hills and other forest of the Saurashtra regions [11]
Summary
The lady fern genus Athyrium Roth (family Athyriaceae) was originally described in 1800 [1] based on Athyrium filix–femina (L.) Roth. Wang were separated earlier from the genus Athyrium Roth Recently all these representatives are treated under a single genus Athyrium [2,3,4,5,6]. It is one of the most diversified genera in the world, having ca. The pteridological studies were carried out by various researchers in the Gujarat [9,10,11,12,13,14,15,16] and a single species They were collected from different forests of Saurashtra, central and south Gujarat. A brief description and photograph (Fig. 1-4) of these four taxa are given as follow for their easy identification
