Scaevola

Belongs within: Goodeniaceae.

Scaevola, fan-flowers, is a pantropical genus of herbs or shrubs, most diverse in Australia, whose asymmetrical flowers have distinctly spreading corolla lobes. Members of the section Xerocarpaea are perennial herbs or subshrubs with flowers forming terminal leafy spikes (Black & Robertson 1965).

Characters (Black & Robertson 1965): Herbs, undershrubs or shrubs; flowers sessile or pedunculate, in the axil of a leafy floral bract and with two narrow bracteoles at base. Sepals 5, short, sometimes minute; corolla slit to base on upper side, lobes subequal, spreading like a fan or the fingers of an open hand; wings equal; auricles absent; stamens free; ovary inferior, two-celled with one erect ovule in each cell, rarely one-celled with one or two erect basal ovules; style usually curved inwards at summit; indusium cup-shaped, ciliate at summit; fruit indehiscent, dry or succulent, endocarp usually bony; seeds oblong, embryo mostly terete.
