Species in the family Proteaceae are almost invariably tetramerous with the stamen adnate to a tepal. Andromonoecious inflorescences bearing many male flowers composed of a single (spathuloid) stamen and a female flower with a pubescent stigma, as in Endobeuthos paleosum, are unknown. We suggest that the specimen is a bisexual flower with scores of stamens surrounding a single stigma-style. Further, the specimen is too old to fit with current understanding of the migratory history of the Proteaceae.
