Raunkiaer’s (1934) system is the most practical one from ecological point of view to determine life-form. This system is based mainly on one feature namely the protection of the perennating buds of shoot-apices to the unfavourable season. Life-forms are assumed to have evolved in direct response to the environment and accordingly the proportion of life-forms in an area would give a clear indication of its climatic zone. Thus biological spectrum is one of the useful parameter for comparison on a geographical scale and is valuable in expressing the differences and similarities among plant communities (Meher-Homji, 1964). The biological spectrum of different regions in India have been determined by several workers (Meher-Homji, 1964, 1981; Roy & Shukla, 1985; Sinha, 1990; Roy et al., 1992; Kumar & Krishnamurthy, 1993; Pandey & Parmar, 1993; Singh & Arora, 1994; Rana et al., 2002; Joshi, 2010; Sudhakar Reddy et al., 2011; Jakhar, 2015). The present study was conducted in Morni Hills of Panchkula district, Haryana. Quantitative analysis of forest vegetation and life-form classes of Morni Hills was conducted by Jain, 1979; Jain et al., 1982; Jain & Singh, 1984. Rout & Gupta (1989) analyzed forest vegetation of Morni hills in northeast Haryana. Kumar (2001) worked on Flora of Haryana. Kumar & Nagiyan (2006) studied trees and shrubs of Haryana. Negi (2010) studied floristic diversity of Shivalik Hills of Haryana. Singh & Vashistha (2014) investigated the flowering plant diversity and ethnobotany of Morni Hills. Gupta & Kumar (2014) studied vegetation composition and plant biodiversity in forest ecosystems of Shivaliks in Northern Haryana. Further the detailed study of life-form and biological spectrum is not available for this region. The present paper deals to determine the phytoclimatic condition of Morni Hills with the help of biological spectrum.
