Diagnostics:
Pemphia acidula is a very rare plant found in coastal or rocky shores. The leaves are oppositely arranged and elliptic in shape. The secondary veins are hardly noticable. Both the leaves and young branches are densely covered with fine white hairs, thus having a smooth texture.
Interesting Facts:
The bisexual flowers have two forms, known as the "pin" and "thrum" flowers (Tomlinson, 1986). The pin flowers has stamens shorter than the pistil while the opposite applies to the thrum flowers.There is now only one natural individual Mentigi in the mainland; growing on reclaimed land in Changi. A big bush at Changi Beach Park was killed by a storm in 2006. Prior to that, it was already badly damaged by reckless campers who "hanged clothes and built barbecue fires under it" (Tan et al., 2010).
Offshore, it can also be found in restricted islands of Pulau Biola, Senang, Sudong, and Salu.
