In my occasional field explorations in the cogon-dominated, cattle-grazed grasslands peripheralizing Balinghasai farms I can say that this is the most abundant native tree species in this part of the Philippines but is also the most exploited for use as fuelwood. Bauhinia malabarica stumps left by wood poachers readily coppice and wildlings emerged to the onset of rain thus the availability of this wood especially for charcoal producers seemed limitless but sometimes the rate of human collection far exceeds the natural capability of the species to reproduce, and this becomes the problem that leads to species decline. Bauhinia malabarica, for now, may be categorized as a common tree but for how long?
Locally called “Alibangbang”, a common reference which it shares also with a number of exotic Bauhinia species which are grown as avenue trees for their colorful and ornate, orchid-like flowers; this mainly due to the very close resemblance of their leaves. This also got a lot of people mistaken in thinking that these large-flowered ornamental Bauhinias are the real Bauhinia malabarica.
True Bauhinia malabarica is an esteemed tree by plant hobbyists and farm owners due to its edible tart leaves. Chopped leaves, particularly the shoots and tips, are used to flavor all sorts of “Sinigang”. At home, we prefer using this over any other sour-imparting ingredients for our “Sinigang na pata ng baka”. Even the regular “Munggong-guisado” and Sauteed sardines (canned) become a little more interesting to the palette when cooked with this vegetable leaf.
