Abstract Within the past decade, Scrophulariaceae sensu lato has been shown to be polyphyletic and, as a result, is currently undergoing major systematic revision. The traditionally recognized family is now generally considered to comprise several smaller families including the newly expanded Plantaginaceae, a family of 12 tribes, 92 genera, and approximately 2000 species. Recent evidence from molecular phylogenetics supports the inclusion of the tribe Gratioleae within the Plantaginaceae… 
Phylogenetic Relationships and Morphological Evolution in the Carnivorous Genus Philcoxia (Plantaginaceae, Gratioleae)
TLDR
The phylogenetic placement of Philcoxia within tribe Gratioleae has been uncertain since its discovery due to its unique morphology and limited data from phylogenetic studies, and the need to reassess the concepts and circumscriptions of some currently accepted genera of the Gratioelae such as Bacopa, Conobea, and Stemodia, and for the tribe Angelonieae.
Phylogenetic relationships, systematics, and biology of carnivorous Lamiales, with special focus on the genus Genlisea (Lentibulariaceae)
TLDR
This analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled the authors to infer more precise phylogenetic hypotheses for the Lamiales tree, and the multiple independent evolution of the carnivorous syndrome is strongly supported by all analyses and topological tests.
Lapaea (Plantaginaceae, Gratioleae), a new genus endemic to the Espinhaço Range (Brazil) with a remarkable red-flowered new species
TLDR
The monophyly of the 'S. stellata group' was confirmed, and its segregation from Stemodia corroborated, and a taxonomic revision of the species recognized in Lapaea is presented, providing an identification key, photos, descriptions, distribution map and notes on their morphology, geographic distribution, habitat, ecology, and conservation status.
Plastome comparison and evolution within the tribes of Plantaginaceae: Insights from an Asian gypsyweed
TLDR
The phylogenomic study revealed the sister relationship between V. ovata subsp.
Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences
TLDR
Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants and the evolution of selected morphological characters such as flower symmetry is discussed.
Phylogeny of Pedaliaceae and Martyniaceae and the Placement of Trapella in Plantaginaceae s. l.
TLDR
The phylogeny indicates the three tribes of Pedaliaceae are monophyletic, but that Sesamum is not, and shows that the two families exhibit a combination of shared floral morphology due to their proximity in Lamiales, and convergent functional morphology for dispersal.
Seed Morphology and Its Taxonomic Significance in the Subtribe Gratiolinae (Plantaginaceae)
TLDR
The diversity in seed surface morphology suggests extensive but taxonomically significant seed variation in the subtribe Gratiolinae.
Underground leaves of Philcoxia trap and digest nematodes
The recently described genus Philcoxia comprises three species restricted to well lit and low-nutrient soils in the Brazilian Cerrado. The morphological and habitat similarities of Philcoxia to those
Dizygostemon riparius (Plantaginaceae, Gratioleae), a new species from Maranhão, northeastern Brazil
TLDR
The new species is assessed as Endangered (EN) according to IUCN categories and criteria and provides diagnostic features that help to differentiate Dizygostemon from the similar Brazilian genera Achetaria, Stemodia and Tetraulacium.
Several origins of floral oil in the Angelonieae, a southern hemisphere disjunct clade of Plantaginaceae.
TLDR
Angelonieae date back to the Uppermost Eocene and diversified in dry areas of southern South America and switched from nectar to oil as a reward four or five times over the past 25 Ma, as predicted in a previous non-clock-dated study.

Piecing together the "new" Plantaginaceae.
TLDR
In a phylogenetic study of 47 members of Plantaginaceae and seven outgroups based on 3561 aligned characters from four DNA regions, the relationships within this clade were analyzed and the results from parsimony and Bayesian analyses support the removal of the Lindernieae from Gratioleae to a position outsideplantaginaceae.
Redefining Phrymaceae: the placement of Mimulus, tribe Mimuleae, and Phryma.
TLDR
In light of the molecular evidence, it is clear that species of Phrymaceae have undergone two geographically distinct radiations; one in western North America and another in Australia (about 30 species).
The Linderniaceae and Gratiolaceae are further lineages distinct from the Scrophulariaceae (Lamiales).
The Lamiales are one of the largest orders of angiosperms, with about 22,000 species. The Scrophulariaceae, as one of their most important families, has recently been shown to be polyphyletic. As a
Further disintegration of Scrophulariaceae
TLDR
A novel, strongly supported, clade of taxa earlier assigned to Scrophulariaceae was found and possibly represents the tribe Lindernieae, diagnosed by geniculate anterior filaments, usually with a basal swelling.
Disintegration of the scrophulariaceae.
TLDR
A molecular systematic study of Scrophulariaceae sensu lato using DNA sequences of three plastid genes revealed at least five distinct monophyletic groups, which are newly erected herein to recognize the phylogenetic distinctiveness of tribe Calceolarieae.
Combining Data in Phylogenetic Systematics: An Empirical Approach Using Three Molecular Data Sets in the Solanaceae
TLDR
Data from sequences of two chloroplast DNA genes, ndhV and rbcL, and from restriction site mapping studies of the entire chloroplane genome were analyzed for the same set of 17 species of Solanaceae and the outgroup Ipomoea, finding the "X = 12" dade is the most well-supported dade within the family.
Monophyly of the Asteridae and Identification of Their Major Lineages Inferred From DNA Sequences of rbcL
A parsimony analysis of 57 angiosperm rbcL sequences was conducted to test the monophyly of the Asteridae and to identify major lineages within the Asteridae. Three major clades, the Caryophyllidae,
The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis.
TLDR
The results of this study show that a survey using as few as three representative taxa can be predictive of the amount of phylogenetic information offered by a cpDNA region and that rate heterogeneity exists among noncoding cpDNA regions.
A taxonomic revision of the Australian species of Limnophila R. Br. (Scrophulariaceae
TLDR
In Australia five species of Limnophila are here recognized: L. arornatica, L. chinensis, L.'sophagus, fragrans and L. gratioloides, an Australian native which has previously been considered conspecific with L. indica.
