I've already posted several photos of acacia trees in this blog. In my little corner of Quezon City, they are still quite numerous and they are also the largest and most magnificent of the trees I see here. Someone commented in one of those previous posts that these acacia trees harbor lots of higad, those fuzzy, spiky caterpillars whose tiny hairs can cause extremely itchy and painful allergic reactions. That's very true. But with higad season (around March or the beginning of summer) over, it's safe to walk underneath them again. These acacias line Roxas Avenue in the Diliman campus of the University of the Philippines.
