Saribus rotundifolius (Lam.) Blume
Saribus rotundifolius or Anahaw in Filipino, is also known as the National Leaf of our country. Ecologically, its leaves can purify air, has a cooling effect, and improves water supply, and its roots hold the soil. Commonly planted as an ornamental plant, its leaves are also used for thatching and wrapping foods.
Leaves are known to be medicinal when crushed and applied on the affected area for fresh wounds, and also used as a decoction to treat diarrhea (Balangcod & Balangcod, 2015). Its straight durable trunk is highly in demand for poles and pillars, flooring, pack carriers, fishing rod bows, canes and spear shafts. It has also proven its viability as a good material in the manufacture of floor tiles (Fernandez, 2008). However, S. rotundifolius is already listed as Other Threatened Species (DENR-DAO 2017-11).
Anahaw trees in the main campus were cultivated in front of the Interfaith Chapel. It is one of the most valued native plants of the University that could provide edible fruits in times of famine. Seedlings of Anahaw are also found strewn around the campus as it can be easily dispersed by birds and by rainwater.
