== Synonyms ==
== Description ==
*An erect spreading shrub or small tree up to 4(-7) m tall; branchlets terete. *Leaves alternate, the majority crowded at the end of the branches, spathulate to obovate, 12-26 cm × 5-10 cm, base attenuate, apex blunt to rounded, margin entire, sinuate to dentate, herbaceous to thin-fleshy, glabrous to shortly tomentose, sessile; stipules absent. *Inflorescence axillary, cymose, laxly branched, about 4 cm long, few-flowered, bracts persistent, peduncle 0.5-2 cm long. *Flowers 5-merous, zygomorphic, 2-2.5 cm long, scentless, white to pale yellow, pedicel 0.3-1.2 cm long, glabrous to densely appressed hairy; calyx adnate to the ovary, lobes linear to narrowly elliptical, 0.2-0.5 cm long, persistent; corolla glabrous to pubescent outside, densely pubescent inside, tube 0.5-1 cm long, lobes membranous, fimbriate towards the base, about 0.5 cm long; ovary inferior, 2-celled, style faintly pubescent at base. *Fruit a fleshy drupe, 1-1.5 cm in diameter, faintly 2-lobed and ribbed, pellucid-white when ripe, stone 0.8 cm × 0.6 cm, 2-seeded. *Seedling with epigeal germination; cotyledons emergent, fleshy; hypocotyl elongated.
== Growth and development ==
== Other botanical information ==
''Scaevola'' has a pantropical distribution and comprises about 100 species, most of them endemic to Australia. The genus is divided in 3 sections. The vast majority of species belong to section ''Xerocarpa'' that is almost exclusive to Australia. Section ''Enantiophyllum'' is confined to eastern Malesia and northern Australia, represented by ''S. oppositifolia'' . Confusion is rampant concerning the nomenclature of the strand ''Scaevola'' species, both belonging to section ''Scaevola'' . The widespread variable species are at present classified as 2 species, ''S. plumieri'' (L.) Vahl with an Indo-Atlantic distribution and ''S. taccada'' with an Indo-Pacific distribution. They are primarily distinguished by the incision of the calyx and the colour of the fruit.
== Ecology ==
''S. taccada'' is a typical constituent of the ''Barringtonia'' formation. It is usually confined to the seashore, restricted to sandy beaches or rock and coral outcrops, occasionally found inland on Pacific atolls in sunny disturbed habitats and rock faces. It is capable of substantial growth and physiological responses, which are required in coastal habitats characterized by large temporal and spatial variations in substrate salinity and salt spray levels. Seaward expansion is limited by a combination of salt spray and substrate salinity.
