Man has surveyed remote galaxies and has stood on the surface of moon but has not so far come anywhere near to completing a taxonomic catalogue of the fewer than half a million species of higher plants growing on our planet. Botanists were exploring the floristic regions of the
The Kerala State lies along the south-west corner of Peninsular India, between 80 18' and 120 48' N latitude and 740 52' and 770 22'E longitude. The boundaries of the State are the Lakshadweep sea in the west, Tamilnadu in the south and east and Karnataka in the north.
The Mountain ranges traversing through the State are considered as the post Jurassic uplifts due to the continental movements. These regions show similarities with some of the mountains in Sri Lanka. Precambrian rock consisting mainly of gneisses, charconites and
The State receives both south-west and north-east monsoons. The mean annual rainfall is 2693 mm. The highest rainfall was recorded (5883 mm) at Neriamangalam and the lowest (651 mm) at Chinnar in Idukki district. The southern parts of Kerala experience
The Malabar coast, well known in the history of plant resource studies in Asia is remarkable for the luxuriant growth of tropical forests. Hooker (1907) classified the botanical regions of the erstwhile British India in to 9 regions based on species distribution. The Malabar region is one among them

The varied topographical features, high rainfall and geologic conditions have favoured the formation of different ecosystems from shola forests on the mountain valleys to the mangrove forests along sea coasts and estuaries.   The compilation based on the floristic studies carried out so far shows that there are 5,094 taxa of flowering plants in Kerala. They belong to 1,537 genera in 221 families. Leguminosae is the
