Conspectus of the Family Convolvulaceae with New Additions in Flora of Uttar Pradesh, India

Abstract

The present study provides a comprehensive taxonomic account of the family Convolvulaceae in Uttar Pradesh, India, revealing significant additions to the regional flora. Based on extensive field surveys and herbarium consultations, a total of 74 taxa, including 71 species distributed across 20 genera, were documented. Remarkably, nine species are reported for the first time from the state: Cuscuta campestris Yunck., Dinetus racemosus (Roxb.) Sweet, Ipomoea capitellata Choisy, I. coccinea L., I. hederacea Jacq., I. laxiflora H.J. Chowdhery & Debta, I. littoralis Blume, I. mauritiana Jacq., and I. triloba L. These new records not only enhance the floristic diversity of Uttar Pradesh but also underscore the ecological range and adaptability of the family in varied habitats. Each species was examined for morphological traits, phenology, floral characteristics, dehiscence patterns, and conservation status. The findings highlight the ecological value of Convolvulaceae in local ecosystems and emphasize the urgent need for region-specific conservation measures, particularly for rare and endemic taxa. This study contributes to the baseline knowledge of regional plant biodiversity and serves as a foundation for future generations.
