The specific epithet oviflorum comes from the Latin ovi meaning egg and florus meaning flower, which refers to this species flower colouration that resembles a fried egg with bright yellow and pure white colours.

Inflorescences are 4–15 cm long and produce white and yellow flowers that bloom from April to August in the southern hemisphere.

S. oviflorum is endemic to the northern area of Queensland from Mareeba and Wairuna west to Barwidgi.

Its habitat is recorded as being sandy soils in seepage areas, on hillsides, or beside creeks in the company of Melaleuca viridiflora, Eucalyptus camaldulensis, or E. cullenii.

S. oviflorum is most closely related to S. fissilobum but differs mostly in the corolla colour and self-supporting stems.
