A very large genus of tropical and temperate-country plants, of which only two Australian species are known, 
one of them tropical, and the other extending from the tropics to Tasmania. — Yery remarkable, twining, parasitical, 
leafless plants, known as Dodders in England, where they do great injury to crops of Clover, etc., with slender, 
thread-like stems, that derive their nourishment by suckers from the plants to which they become attached ; the 
seeds germinate in the ground by means of a spiral, undivided embryo, and the young plant, when fully developed, 
decays away near the root, and continues thenceforth to live wholly on the plant it has attached itself to. — Flowers 
rather small, in heads or eta -parent. Calyx four- or five-lobed. Corolla ureeolate, four- or 
five-lobed. Stamens four or five, epipetalous, generally subtended by small scales. Ovary two-celled, cells two- 
ovuled ; styles two, sometimes combined. Capsule indehiscent or bursting transversely. — The Tasmanian C. Aus- 
tralis is distinguished by : 
smooth, deeply five-lobed cah \ sorolla, with five short, recurved lobes; the 
scales beneath, but attached to the dilated filaments 
ful origin.)
