In the present study an attempt has been made to correlate the different soil factors with the growth of four different species of Isoetes L. Soil collected from natural habitats of Isoetes have been analysed for colour, texture, pH and available plant nutrients. The present analysis revealed that the habit of the plant of different species is influenced by edaphic diversity. It has also been found that the genus Isoetes is one of the most edaphically diversified genera of the pteridophyta. There was certain sensitivity of plant length in relation to the various soil factors. The lower scale of acidity favored the growth of Isoetes. The length of the plant decreases with the altitude. The nutrients like, zinc, manganese, iron and copper present in the soil showed significant relationships with the growth of the plants.
