From the Greek words angeîon which means “vessel, container” and spermos “having a seed”, angiosperms are a division under the plant kingdom that produces seeds enclosed in the reproductive structures of a  flower. It is the most diverse and widely distributed plant group on the planet due to its innovation in its reproductive, vegetative, and genomic biology. They are characterized by their reproductive structures called flowers, which eventually develop into fruits bearing seeds. With a complex vascular system, broad leaves, and diverse life cycles, angiosperms have adapted to various environments and play crucial roles in ecosystems. Countless organisms, including humans, rely on them for food, shelter, and resources. Their economic importance is extensive, encompassing food crops, medicinal plants, and ornamentals, making them critical to human survival and biodiversity. 

The university grounds were also the collection site for the angiosperms. Once a weedy plant was chosen, a rapid, visual assessment was conducted to observe if there were at least 10 plant individuals in an area before it was dug from the soil. Only the terminal flowering shoots were obtained from larger plants that extend beyond the knees. Upon cutting, the plant specimens were generously sprayed with denatured alcohol and bagged in a resealable bag. It is then pressed using newspapers and a wooden press to dry, arranged in a similar form to be mounted in an herbarium sheet.
