Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville, an 18th century patron of botany and co-founder of the Royal Horticultural Society. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae.

Stylidium diceratum is a dicotyledonous plant that belongs to the genus Stylidium. The specific epithet diceratum is Greek for "two horns", referring to the two appendages that are present on the bend of the gynostemium. It is an annual plant that grows from 15 to 35 cm tall. The longer leaves are lanceolate and the shorter ones are spathulate, forming a basal rosettes around the stem. The leaves are around 5–8 mm long and 0.2-2.5 mm wide. Inflorescences are around 6–15 cm long and produce flowers that are orange with dark orange and pink veins and bloom from June to August in their native range. S. diceratum is only known from the type location, which is at creek crossings on the road to Beverley Springs in the Kimberley region of Western Australia. Its habitat is recorded as being sandy soils on creek margins. It grows in the presence of S. ceratophorum, S. rubriscapum, Drosera caduca, D. paradoxa, Byblis liniflora, and Grevillea pteridifolia. S. diceratum is most closely related to S. longicornu, but it can be confused with S. ceratophorum, which also has an orange corolla but twice as large.

Grevillea cyranostigma, commonly known as the Carnarvon grevillea or green grevillea, is a shrub species that is endemic to Queensland in Australia. It was first formally described by Don McGillivray in 1975. He named it cyranostigma after Edmond Rostand's Cyrano de Bergerac, as its long stigma was reminiscent of the character's protruding nose. The type specimen was collected between 1890 and 1895 by Harriette Biddulph of Mount Playfair Station, who was known for her collection of plants from the Carnarvon Range. The species appears to be related to Grevillea sericea and G. victoriae, and is distinguished by glossier leaves than the former and a less hairy perianth than both.
