Floristic Diversity of Wild Exotic Ornamental Species from Aravalli Hill Ranges of Rewari District of Haryana, India


The Aravalli hill ranges are known for their unique composition of native and exotic flora. The region harbors a large number of exotic plants, which escalate and laud our environmental elements, provide an uplifting outlook towards life, improve estate esteem, and create a sense of prosperity and joy by utilizing these exotics for orna­­­­­mental purposes. The present study was conducted to enumerate wild exotic ornamental plants of the Aravalli hill ranges along with their common names, family, habit, nativity, the continent of origin, ornamental attributes, and purposes. The present study revealed the utilization of 42 wild exotic ornamental species belonging to 21 families from the Rewari district for various ornamental attributes and purposes. The documented planted showed diversity in taxonomic dispersion with 39 dicots, a monocot, and 2 ferns (Adiantum rhizophytum, Asplenium radicans) species. Asteraceae (8), Fabaceae (5), Amaranthaceae (4), Malvaceae, Euphorbiaceae, and Solanaceae (3 each) were the most dominant plant families. The spatial distribution of the plant species was dominated by Herbs (71%), Shrubs (12%), Trees (7%), Climbers, and Ferns (5%) respectively. The wild exotic ornamentals shared their nativity and origin from S. America (29%), C. America (24%), African (15%), Asian (13%), Mediterranean region (8%), European (6%), North American (4%) and least from Madagascar (2%). The present study recommends the use of wild exotic ornamentals as they are an important tool in the reduction of deforestation and land degradation. It is also assumed that Wild exotic ornamental plants may help in increasing genetic diversity and remodeling of urban ecosystems.
