Lagerstroemia calyculata

Lagerstroemia calyculata known as the "Guava Crape Myrtle" (Vietnamese name : "Bằng Lăng Ổi", "Bằng Lăng Cườm"; "tabaek"; Cambodian name: Srolao "ដើមស្រឡៅ"); the name is derived from its very characteristic mottled flaky bark. It is a species of flowering plant in the family Lythraceae and found in Southeast Asia and Oceania.
It is a medium-sized tree growing up to a height between 10 and 20 m. Like other species of the same genus, it is quite common as a decorative tree in the parks of Thailand owing to its beautiful bunches of pink flowers. Its wood has a low commercial value, which is why it thought to have maintained the forest structure in previously logged parts of Cat Tien National Park, where it may constitute >25% of tree counts.
