This research was concerned with identifying, classifying, naming, and providing a botanical description of the angiosperms present in Saint Louis School Inc. located on Quirino Highway, Baguio City, to raise the awareness of students and personnel on present angiosperms. It is concerned with suggesting ways how to preserve and conserve the different flowering plant species present in the school vicinity. There are 44 plant species identified belonging to 26 families namely Acanthaceae (2), Alstromeriaceae (1), Amaryllidaceae (3), Apocynaceae (4), Araceae (2), Asphodelaceae (1), Asteraceae (4), Begoniaceae (2), Bignoniaceae (2), Bromeliceae (1), Caryophyllaceae (1), Convolcuceae (1), Crassulaceae (1), Ericaceae (1), Euphorbiaceae (1), Geraniaceae (2), Lamiaceae (3), Lythraceae (1), Malvaceae (2), Melastomataceae (1), Nyctaginaceae (1), Orchidaceae (2), Rosaceae (1), Rubiaceae (2), Solanaceae (1), and Verbenaceae (1). Plants belonging to Apocynaceae and Asteraceae have the highest number of plant species. Only a general way of conservation of angiosperms was provided. As a result, a follow-up study on specific ways how to conserve plants that will cater to their different needs is highly recommended. Based on the results, Saint Louis School Inc. is filled with diverse beautiful angiosperms. It is important to maintain, put effort into conserving these flowering plants, and have a deeper appreciation towards them, especially as learners and personnel of SLSI.
