Endemic species are indigenous to a geographical region and hence have area restrictedness. Diversity of such species is measured in terms of a unit called the species count. It gives an indicator of the number, type, location (geographical) and other variations in a particular site, i.e., primulla and potentilla at high altitudes of Himalayas.

There are 25 clearly defined areas in the world called 'hot-spots' which support about 50,000 endemic plant species, comprising 20 per cent of the world's total flora. India's defined location of 'hot-spots' is the Western Ghats and the North Eastern regions. About 4,900 species of flowering plants are 33 per cent of the recorded floras are endemic to the country.

These are distributed over 141 genera belonging to 47 families. The Western Ghats is well-known for harboring 14 endemic species of caecilians (i.e., legless amphibians) out of 15 recorded from the region so far.
