This research aims to conduct a comprehensive inventory of plants in South Kalimantan while delineating their significance from the ethnobotanical perspective of the Banjar people. Employing descriptive and qualitative research methodologies, data collection involved a triad of methods: observational studies, interviews, and extensive library research. The study followed a structured sequence encompassing observation, data collection, presentation, analysis, and conclusive inferences. Rooted in ethnobotany theory with an ethnographic approach, this investigation aimed to unearth the intrinsic relationships between the Banjar community and their local flora. The findings unveiled a rich lexicon of plant names in South Kalimantan, particularly spotlighting categories such as swamp plants (Nypa), woodproducing species (Eusideroxylon zwageri), fruit-bearing flora (layung), lemongrass (Cymbopogon citratus), ornamental plants (e.g., bird nest fern or Asplenium nidus), and yam plants (Manihot esculenta). Additionally, the indirect consumption of fruits, such as sugar palm (Arenga pinnata), and vegetables like yellow velvet leaf (Limnocharis flava), were documented. This research sheds light on the multifaceted roles that South Kalimantan's plants play within the socio-cultural and utilitarian framework of the Banjar people. Understanding the intricate connections between the local flora and the Banjar community not only enriches ethnobotanical knowledge but also underscores the significance of indigenous plant life in sustaining traditional practices and livelihoods.
