A Conspectus o f the Tribe Vernonieae (Asteraceae) in India
Abstract and Figures
A conspectus of the tribe Vernonieae (Asteraceae) in India is provided which includes 9 genera, 64 species (including 1 cultivated and 5 doubtful species), 1 subspecies and 3 varieties (including 1 doubtful variety; excluding variety proper) among which 2 genera, 27 species and 1 variety are endemic to India. A new combination viz., Vernonia mastersii (Strobocalyx mastersit) has also been made in this treatment.

... specimens of extant species of Uniyala suggested that four of the paleotropical Vernonia species endemic to southern India have very close affinities Uniyala. The morphological characteristics (Gamble 1921, Rau & Narayana 1983, Uniyal 1995, Robinson & Skvarla 2009), palynology (Vasanthy 1985), and the distribution restricted to the southern Western Ghats, particularly Kerala and Tamil Nadu states (Gamble 1921, Uniyal 1995, Bhattacharjee et al. 2019; see also https:// powo.science.kew.org/) of Vernonia anamallica, V. bourneana, V. gossypina and V. malabarica clearly correspond to the diagnostic features of Uniyala rather than to those of Vernonia s. stricto. Gamble (1921) treated all the shrubby or subshrubby Vernonia species with paleaceoushairy outer pappus under one group, and some of them were later transferred to Uniyala by Robinson and Skvarla (2009). ...
Based on morphological, palynological and phytogeographical evidence, four new combinations in the genus Uniyala (Asteraceae) are proposed: U. anamallica (Bedd. ex Gamble) K. Sampath Kumar & Arum., U. bourneana (Sm.) Arum. & K. Sampath Kumar, U. gossypina (Gamble) K. Sampath Kumar & Arum., and U. malabarica (Hook. f.) Arum. & K. Sampath Kumar. Lectotypes are designated for the names Vernonia malabarica Hook. f. and V. gossypina Gamble, and a key to all the species of Uniyala is provided.
New subtribes Stokesiinae and Pacourininae are established in the Vernonieae (Asteraceae) for the Southeastern United States genus Stokesia and the South American genus Pacourina.
The genus Critoniopsis is found to have 18 species in Ecuador. The treatment includes the removal of a previously cited species for the country, C. bogotana, the reduction of C. sevillana to a variety of C. floribunda, and the description of three new species: Critoniopsis cerulosa, C. persetosa and C. zamorensis. A key for identification of the currently credited species is provided and notes on the distribution and taxonomic problems are presented.
