Its flowers are small and not fragrant, each has six delicate white petals and come from stalks 5–15 mm long.

Uses
The wood of this species has been traditionally valued in many cultures for it is hard and heavy, as well as resistant to rot and warping. It also has naturally a fine finish and may be fashioned into walking canes, fence posts, tool handles, and even anchors. In Réunion and Mauritius it is known as bois matelot. In the Maldives this hardy wood was used in traditional shipbuilding to hold the planks of the hull together, as well as to fashion "nails" in local sorcery.

Pemphis acidula is also one of the plant species used in bonsai. Due to its tropical preference and typhoon-resistance, it is the most common species for bonsai in the Philippines; but it is also grown as bonsai in Taiwan and the Ryukyu Islands of Japan.

The collection, selling, and transport of wild Pemphis acidula is illegal in the Philippines and punishable by fines and imprisonment of up to six years.

In Marovo Island, Tonga, Tahiti, and other South Pacific islands, it is used to make wooden tools such as pestles, tool handles, weapons, and combs.

In Taiwan's Kenting National Park illegal picking has had a negative impact on the coastal ecosystem.
