New Distributional Record and Morphological Characterization of Emilia sonchifolia (L.) DC. from South-Central Rajasthan

Abstract

The species Emilia sonchifolia (L.) DC., belonging to the tribe Senecioneae in the Asteraceae family, is widely known for its ecological significance and medicinal properties. This study documents its first-ever record from the semi-arid Lakhola region in Bhilwara, Rajasthan, highlighting its adaptability to diverse environmental conditions and expanding its known distribution range. The primary objective was to describe its morphological characteristics, evaluate its ecological adaptability, and contribute to its taxonomic understanding. Field surveys were conducted to collect specimens, which were analyzed for detailed morphological traits. Standard taxonomic protocols were followed to compare the species with related taxa. Geographic and ecological data were also recorded to understand its habitat preferences. The study revealed distinct morphological features, including variable leaf forms, tubular pink to purple flowers, and narrow-obloid achenes with a pappus, aiding in species identification and classification. Its presence in the semi-arid region indicates ecological resilience and adaptability to Rajasthan's climatic and soil conditions. These findings are significant in bridging gaps in the distribution and taxonomy of Emilia sonchifolia and highlight its potential for further studies on medicinal applications and propagation methods. The study concludes with recommendations for in-depth research into its ecological interactions and conservation strategies, emphasizing its importance to local biodiversity and sustainable utilization.
