Two new genera and species of Linderniaceae (Lamiales) from inselbergs in northeastern Brazil: morphological and karyological evidence
During field studies of the inselbergs of northeastern Brazil, two potentially new species of were discovered. They share morphological characters with several genera of Linderniaceae (Lamiales) such as Ameroglossum , Cubitanthus and Stemodiopsis , but the morphological differences are such that they do not make a good fit with any...Almeida, Erton ; Wanderley, Artur ; Santos, Amanda ; De Melo, JosÉ ; Souza, Gustavo …

Plastid phylogenomic insights into the evolution of Caryophyllales
The Caryophyllales includes 40 families and 12,500 species, representing a large and diverse clade of angiosperms. Collectively, members of the clade grow on all continents and in all terrestrial biomes and often occupy extreme habitats (e.g., xeric, salty). The order is characterized by many taxa with unusual adaptations including carnivory,...Yao, Gang ; Jin, Jian-Jun ; Li, Hong-Tao ; Yang, Jun-Bo ; Mandala, Venkata …

Phylogenetics, classification and typification of extant horsetails (Equisetum, Equisetaceae)
Horsetails (Equisetum, Equisetaceae) are one of the oldest groups of vascular plants with a nearly continuous fossil record dating back to the Carboniferous. Only a few studies have addressed relationships among and within the extant members of this fern genus. We here present the first complete phylogenetic analysis of one...Christenhusz, Maarten ; Bangiolo, Lois ; Chase, Mark ; Fay, Michael ; Husby, Chad …

‘Unknown yellow’: Pibiria, a new genus of Passifloraceae with a mixture of features found in Passifloroideae and Turneroideae
In 1993, a shrub with yellow flowers reminiscent of but obviously distinct from Turnera was found near Mabura Hill in central Guyana, which was recollected in 2000. This paper offers a morphological description including leaf and wood anatomy and pollen morphology in addition to a phylogenetic analysis based on plastid...Maas, Paul ; Baas, Pieter ; Christenhusz, Maarten ; Clarkson, James ; Koek-Noorman, Jifke …
