Morphology
Description

Inflorescence axillary dichasia or cyme , pedunculate. Flowers hermaphroditic, zygomorphic , 5- merous , bracteolate; calyx synsepalous, cup-like, persistent ; corolla tubular, with adaxial deep split (exposing indusium), fan-like, winged (appearing trilobed), hirsute within; stamens 5, opposite sepals, free of corolla , anthers dehisce in bud , introrse; gynoecium syncarpous, ovary inferior, carpels 2, locules 2, style with hairy pollen -collecting indusium and stylar cup, stigma bilobed. Fruit a drupe , hard, indehiscent with thick endocarp and fleshy or corky mesocarp . Seed 1 per locule .

General Description
Notes on delimitation
  • Currently circumscribed in the Asterales as sister group to Calyceraceae and Menyanthaceae (Stevens 2008). Placed in the Campanuales by Cronquist.
Number of genera
  • 1 Genus:  Scaevola L. with 3 species.
Status
  • Scaevola plumieri occurs throughout the Neotropics.
  • S. wrigtii is endemic to eastern Cuba.
  • S. taccada is an exotic invasive found in the British Virgin Islands.
General notes
  • Scaevola: (from the Latin scaevus meaning 'left-handed') - a reference to a legendary one-handed Roman hero Mucius Scaevola, who was likened to the genus, as its flowers appear to have been cut in half.
  • Insect pollinated.
Distribution
Distribution in the Neotropics
  • Scaevola plumieri (L.) Vahl can be found throughout coastal areas of the Neotropics.
  • S. wrigtii (M.Gomez) is endemic to eastern Cuba.
  • S. taccada (Gaertn.) Roxb (= S. sericea Vahl) is a paleotropical species naturalized in the British Virgin Islands.
Diagnostic
Distinguishing characters (always present)
  • Members of the Neotropical Goodeniaceae are readily distinguished by an unique floral character known as the 'indusium' which is a cup-shaped specialized stylar outgrowth below the apex of the style (that attracted the interest of Charles Darwin), and which acts as a pollen presenter.
Other important characters
  • The fan-shaped corolla and marginal membranaceous wings making each lobe appear trilobed.
  • Barbulae (hairy outgrowths) found at the edge of petal wings and down into the throat.
  • Indehiscentfruit, which lacks a clear demarcation between the hard endocarp and outer layers with unthickened cell walls.
