Evolvulus nummularius (L.) L. of the Convolvulaceae family has a pantropical distribution, but its occurrence is reported first time in the Philippines. The discovery of this alien species began during the photo documentation of the plant specimens in the botanical garden at the College of Science and Mathematics, University of the Philippines Mindanao campus. It was found growing on clayey soil and thought to be naturally growing in the botanical garden. However, we found out that it was intentionally planted as a cover crop to avoid soil erosion and to reduce mud formation on the pathway to the garden during rainy days. The species is believed to be introduced in the country by traders or enthusiasts as an ornamental or medicinal plant. Though its cultivation is contained within the botanical garden, the species is considered invasive in many countries. Therefore, its cultivation needs to be regulated, and proper management must be put in place in the botanical garden in order to prevent its possible colonization in surrounding areas and across the country
