"For a long time I have held my peace, I have kept myself still and restrained myself; now I will cry out like a woman in labor, I will gasp and pant" (Is 42:14)

Rain Tree or Five O'Clock Tree

A giant "Acacia" along the Biga riverbank at Dalnacan Cogawe, Brgy Cudal, Tabuk City, Kalinga, Philippines
amanea saman, commonly known as the Rain Tree, Five O'Clock Tree, or Cow Tamarind belongs to the pea or legume family (Fabaceae). It was introduced to the Philippines during the Spanish colonial period. Ever since its arrival, it has been known confusingly as "acacia"—a misnomer (a name that is incorrectly or unsuitably applied) by its resemblance to native Acacia species. The leaves fold during rainy weather and in the evenings, hence, the names rain tree and five o'clock tree.

It is believed to have been brought to the country in the early 19th century, although the exact date and the person responsible for its introduction are not well documented. It has been widely introduced to South and Southeast Asia, as well as the Pacific Islands, including Hawaii.

The tree is native to Central and South America and was likely treasured for its shade and ornamental value, as well as its potential use in timber production. Its wood is used for carving and making furniture. The fruit or pod is eaten, with the young leaves as a salad. The fruit pulp can be made into a beverage that tastes like lemons.

Over time, Samanea saman has become naturalized in the Philippines and is now commonly found throughout the country, particularly in urban areas and along roadsides and plazas. The Department of Environment and Natural Resources (DENR) even declared these trees as heritage, centennial, or historical trees, especially those with a diameter of 1 meter or more. 8thworker.us
