Abstract

The genus Kleinia Miller (1754: page headed KI KL) (Asteraceae, subfam. Asteroideae, tr. Senecioneae) has been variously circumscribed over time, but in the past was often regarded as worthy of segregation from Senecio Linnaeus (1753: 866) based on, inter alia, the architecture of ovary wall crystals (Jeffrey 1986) and the prevalence of stem succulence (Halliday 1988: 1) and, to some degree, leaf succulence (see Cicuzza et al. 2017 for an overview). The recently described genus Curio Heath (1997: 136) accommodates mostly low-growing to medium-sized leaf succulents with rather dull-coloured capitula that generally lack ray florets.
