The UMYU Herbarium at Umaru Musa Yarádua University in Katsina, Nigeria, features a collection that primarily focuses on the flora of the Sahel and Sudan savanna regions of Nigeria. The collection has a strong emphasis on taxonomic representation, particularly within the Fabaceae, Poaceae, and Asteraceae families, reflecting the regional biodiversity. Geographically, it encompasses specimens from various habitats across northern Nigeria, including grasslands, forests, and semi-arid regions.

Temporally, the herbarium includes specimens collected recently, as the herbarium was established around 2008. The preparation methods predominantly involve dried, pressed plant specimens mounted on herbarium sheets. This collection supports taxonomic, ecological, and conservation research, providing a valuable resource for studying the region's flora.
