In the present paper, the vascular plants of Andaman and Nicobar Islands, belonging to 204 families, 1045 genera and 2315 species have been put to their exact life forms and percentage belonging to each life form class. The same has been compared with Raunkiaer's normal and other spectra determined in different parts of the country. Phanerophytes, Chamaephytes, Hemicryptophytes, Geophytes or Cryptophytes, Therophytes, Lianas and Epiphytes represent 49.40, 12.14, 7.48, 3.37, 12.31, 9.49 and 5.81 percentage respectively and it has been found that the phyto-climate of these islands is typical phanerophytic which is characteristic of the humid tropics and subtropics.

Abstract


In the present paper, the vascular plants of Andaman and Nicobar Islands, belonging to 204 families, 1045 genera and 2315 species have been put to their exact life forms and percentage belonging to each life form class. The same has been compared with Raunkiaer's normal and other spectra determined in different parts of the country. Phanerophytes, Chamaephytes, Hemicryptophytes, Geophytes or Cryptophytes, Therophytes, Lianas and Epiphytes represent 49.40, 12.14, 7.48, 3.37, 12.31, 9.49 and 5.81 percentage respectively and it has been found that the phyto-climate of these islands is typical phanerophytic which is characteristic of the humid tropics and subtropics.
