• Comment: nom. illeg., nom. superfl., as the epithet crassifolius was available in Colobanthus in 1836 and thus ought to have been adopted by Fenzl. The name Colobanthus billardierei Fenzl var. billardierei is listed by A.D.Chapman, Austral. Pl. Name Index 757 (1991), but this autonym does not exist, in accordance with ICN Art. 22.5 (Melbourne Code, 2012).
