It is a sprawling shrub to small tree, typically reaching a height of 1–5 m (3.3–16.4 ft) and a canopy spread of 1–3 m (3.3–9.8 ft), but is extremely variable in size and shape. Like other members of the genus, S. ellipticum is a hemi-parasite, deriving some of its nutrients from the host plant by attaching to its roots.

Wilkesia hobdyi, the dwarf iliau, is a species of flowering plant in the family Asteraceae that is endemic to the island of Kauaʻi in Hawaii. It was first collected in 1968, and was not formally described until 1971. The number of living plants is estimated at fewer than 300. It is considered Critically Imperiled in global rank which means it is at very high risk of extinction. It has been a federally protected species since 1992. The genus Wilkesia is one of three genera constituting the silversword alliance, a group of highly diverse yet genetically exceedingly closely related species, all thought to be descended from a colonizing ancestor related to the tarweed of North America.
