Characteristics of Beach Naupaka Tree (Scaevola taccada) in the Wild

Scaevola taccada
Beach Naupaka or Naupaka Kahakai (Scaevola taccada) is a flowering plant found on tropical coasts in the Indo-Pacific region. It is a tree that grows in the form of a shrub and is common throughout the Arabian Sea, the tropical Indian Ocean as well as tropical islands in the Pacific Ocean.

This tree is often planted as an ornamental plant in homes or villas that are close to the beach because of its low growth and beautiful leaves.

Scaevola taccada is similar to Scaevola plumieri. S. taccada has clear petal lobes and white berries where the petal lobes remain. S. plumieri has short or absent lobes on the petals and the fruit is black when ripe.

In the past, the two were considered to be the same and had a confusing Latin name. But today what is better known is Scaevola taccada and its popular synonym is Lobelia taccada, published by Joseph Gaertner in 1788.
