Akasya
Albizia saman (Jacq.) F. Muell.
Albizia saman (Jacq.) F. Muell.
Commonly known as Akasya or Rain tree because its leaves fold down during a rainy weather so the raindrops are flowing immediately downwards to the grasses and to the other plants below it.
Despite of it being widely sourced because of the good quality timber and as livestock feed for local consumption, this tree species is assessed as Least Concern in conservation status with stable population trend by the IUCN in 2019. Aside from being an ornamental tree in parks and sidewalks, the decoction of the inner bark and fresh leaves is used in treating diarrhea. On the other hand, its wood is used for carving items, furniture, paneling, posts, plywood, boxes, and crates while the trunk and branches are used for firewood and charcoal. In addition, its wood is also good in making paper. In the province of Bulacan, shavings made from its wood are also made into hats.
Do you want an interesting fact? We also have Akasya that can be found near the PUP Oval which was estimated to be at least 50 years of age as it was already seen on year 1971 during the administration of Dr. Isabelo Crisostomo. In other words, the Akasya in our campus can possibly be considered soon as an ‘heritage tree’ due to its age and historical value!
