Biology: G. gaudichaudii is, next to G. migrans, the most common species in S.Aust. and varies from delicate little-branched annuals to densely tufted perennials with a somewhat woody tap root. It is distinguished by its almost sessile flowers and fruit being often clasped by the subtending linear leaves and its internodes which are usually 10-20 mm long at least on some parts of the plants.
