Inflorescence: Flowers blue or blue purple, veined yellow or white, 20mm across; sepals large to 15mm, with retrorse eglandular hairs, mucro 2mm, flower buds oval, not furry. Foveole usually eglandular, with 0-2 (-3) ridges, beak 40-50mm. 2n=60

Distribution: Australia; mostly western Australia but eastwards to Ayer’s Rock, and Lake Gillies in South Australia.

 

Synonyms: E. angustilobum Carolin - Carolin (1970) distinguished E. angustilobum from E. cygnorum on the basis of its narrow leaf lobes. However, E. cygnorum shows a large variability in leaf shape and size, which includes those with narrow lobes. These forms have no other

associated distinctive character, and consequently E. angustilobum is now considered a synonym of E. cygnorum.
