Abstract
1, 119 species of spermatophytes recorded from the Punjab State have been analysed as to their exact life-forms. These include 243 (21.7%) phanerophytes, 49 (4.4%) chamaephytes, 83 (7.4%) hemicryptophytes, 215 (19.2%) cryptophytes and 529 (47.3%) therophytes. Similar analyses have also been made for the two floristic subunits of the Punjab State, namely semi-arid Punjab and Punjab Shivaliks. These have been compared with Raunkiaer's normal and other spectra of contiguous and comparable areas. The phytoclimate of the State and its floristic sub-units have been found to be therocryptophytic which is characteristic of semi-arid and intensively cultivated areas. The results support Raunkiaer's concept of correlation between the phytoclimate and statistical distribution of life-forms in the flora of a region.
