Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses [PDF]
, 2020 Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense.

A revision of the Solanum elaeagnifolium clade (Elaeagnifolium clade; subgenus Leptostemonum, Solanaceae) [PDF]
PhytoKeys, 2017 Le clade Solanum elaeagnifolium (clade Elaeagnifolium) contient cinq espèces de petits arbustes, souvent rhizomateux, provenant des déserts et des forêts sèches d'Amérique du Nord et du Sud. Les membres du clade étaient auparavant classés dans les sections Leprophora, Nycterium et Lathyrocarpum, et on ne pensait pas qu'ils étaient étroitement liés.

Test a Clade in Phylogenetic Trees [PDF]
Molecular Biology and Evolution, 2006 We develop a new method for testing a portion of a tree (called a clade) based on multiple tests of many 4-taxon trees in this paper. This is particularly useful when the phylogenetic tree constructed by other methods have a clade that is difficult to explain from a biological point of view. The statement about the test of the clade can be made through
