New Distributional Evidence of Laggera crispata from South-Central Rajasthan, India

Shahdab Hussain, Jayant Sharma

Abstract: The genus Laggera (Asteraceae) comprises aromatic herbs primarily distributed in hot and humid regions of Asia and Africa. Among its species, Laggera crispata (Vahl) Hepper & J. R. I. Wood holds significant taxonomic, ecological, and pharmacological importance. This study presents a detailed taxonomic investigation of Laggera crispata, focusing on its morphological traits, habitat preferences, and ecological adaptations. The species was first documented in South-Central Rajasthan (Lakhola, near Gangapur), a semi-arid region with diverse vegetation. Field studies (October?December) assessed its distribution and morphological traits, with identification verified through standard taxonomic methodologies. Morphological analysis revealed distinct adaptations, including a fibrous root system, oblong-lanceolate serrated leaves, and corymbose panicle inflorescence, facilitating pollination and seed dispersal. The study highlights the species? resilience to semi-arid conditions and its ethnomedicinal uses, warranting further pharmacological research. Future studies should explore its molecular phylogenetics, physiological responses, and bioactive compounds. This research enhances taxonomic clarity, biodiversity conservation, and sustainable medicinal applications while emphasizing the need for conservation strategies to protect its habitat under increasing environmental pressures.
