Leptoseris yabei

(Pillai and Scheer, 1976)

Colonies are laminar, in whorls or tiers or vase-shaped. They are commonly over one metre across. Corallites are enclosed in rectangular pockets formed between radiating ridges and low walls which are parallel to frond margins. Septo-costae are moderately exsert and alternate.

Colour: Usually pale brown or yellowish, sometimes with white margins.

Habitat: Usually found on flat substrates.

Abundance: Uncommon but conspicuous.
