Abstract Lessingianthus plantaginoides (Vernonieae, Asteraceae) is a small natural tetraploid shrub that inhabits rocky highlands from South America. The population studied inhabits and covers an extensive region of a private reserve with high local

Abstract Palynological data have been used in Vernonieae for generic and specific delimitations, particularly in the Lepidaploinae subtribe. For this reason, pollen studies in the genus Lepidaploa are important to solve taxonomic conflicts. We charac

ABSTRACT Lepidaploa is a taxonomically complex genus of Vernonieae, which is difficult to delimit morphologically due to vegetative and reproductive characters that overlap with Chrysolaena and Lessingianthus. Anatomical studies of cypselae are taxon

—Circumscription of genera in the tribe Vernonieae is complex due to overlapping morphological features among genera such as Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus. These genera have been segregated from the genus Vernonia s. l.,

The genus Stenocephalum Sch.Bip. (Vernonieae, Asteraceae) can be distinguished from the remaining South American members of the tribe by 4–11 florets per capitula, cylindrical involucres and cymose inflorescences. It can also be separated from othe
