Despite extensive efforts, there are unresolved questions on evolutionary relationships in the angiosperm family Rubiaceae. Here, information from six loci and 149 Rubiaceae taxa provide new insights. Acranthera and Coptosapelta are strongly supported as sisters. Pollen grains of Acranthera possess several features common in Rubiaceae, but amongst potential similarities with the unusual grains of Coptosapelta are the nature of the apertures and the structure of the sexine.

Evolutionary relationships in the Spermacoceae alliance (Rubiaceae) using information from six molecular loci: insights into systematic affinities of Neohymenopogon and Mouretia

This work addresses evolutionary relationships in the Spermacoceae alliance (Rubioideae) with special emphasis on the Asian genera Mouretia and Neohymenopogon, here sequenced for the first time.

Towards a better understanding of intertribal relationships and stable tribal delimitations within Cinchonoideae s.s. (Rubiaceae).

Target capture data resolve recalcitrant relationships in the coffee family (Rubioideae, Rubiaceae)

A robust phylogenetic hypothesis of Rubioideae is inferred with the vast majority (or all) nodes being highly supported across all analyses and datasets and few incongruences between the inferred topologies.

Time Tree of Rubiaceae: Phylogeny and Dating the Family, Subfamilies, and Tribes

This study estimated the phylogeny for 534 Rubiaceae taxa from 329 genera with up to five different chloroplast regions by Bayesian analysis, resulting in a highly resolved tree with many strongly supported nodes.

Phylogenetic affinities of Myrioneuron and Cyanoneuron, generic limits of the tribe Argostemmateae and description of a new Asian tribe, Cyanoneuroneae (Rubiaceae)

A robust phylogeny of Rubioideae was reconstructed with sequence data from five plastid regions of 176 accessions and using the Bayesian Markov chain Monte Carlo and parsimony methods, and a new key to the genera of Argostemmateae is provided.

Phylogenetic structure and clade circumscriptions in the Gardenieae complex (Rubiaceae)

The phylogeny of this large and diverse Rubiaceae-Gardenieae and closely related tribes Bertiereae, Coffeeae, Cremasporeae, Octotropideae, and Pavetteae is reconstructed using an extensive sampling of 108 genera and five plastid DNA regions.

Molecular systematics and morphological character evolution of the Condamineeae (Rubiaceae).

Morphological ancestral state reconstructions indicate that protogyny have evolved at least two times within the Condamineeae and that indehiscent fruits, loculicidal fruit dehiscence, and intrapetiolar stipules have evolved independently several times.

The present study includes the first chromosome counts reported for the tribes Cordiereae and Hillieae, as well as for 10 genera and 27 species, providing new aspects of Rubiaceae systematics.

Phylogenetic relationships and new tribal delimitations in subfamily Ixoroideae (Rubiaceae)

A revised tribal classification, including the description of five new tribes, Airospermeae, Augusteae, Scyphiphoreae, Steenisieae and Trailliaedoxeae is provided, to resolve the phylogeny and assess the tribal delimitations in the expanded Ixoroideae.

A phylogeny of Urophylleae (Rubiaceae) based on rps16 intron data

Using sequence data from the rps16 intron to address the question where the four genera Temnopteryx, Pentaloncha, Pleiocarpidia, and Poecilocalyx belong, it is shown that there is conflict regarding the resolution among lineages in Rubioideae, which partly affects the support for relationships within Urophylleae.

Combined phylogenetic analysis in the Rubiaceae-Ixoroideae: morphology, nuclear and chloroplast DNA data.

The combined analysis resulted in higher resolution compared to the separate analyses, exemplifying that combined analyses can remedy the incapability of one data set to resolve portions of a phylogeny.

Palynological characters and their phylogenetic signal in Rubiaceae

The systematic usefulness of pollen morphology in Rubiaceae is discussed at the (sub)family, tribal, generic, and infraspecific levels, using up-to-date evolutionary hypotheses for the different lineages in the family.

Phylogeny and classification of the subfamily Rubioideae (Rubiaceae)

P phylogenetic analyses of the subfamily Rubioideae (Rubiaceae) based on three different pieces of chloroplast DNA, the protein coding rbcL gene, the spacer sequence betweenatpB andrbcL, and the recently published rps16 intron data are performed.

Phylogeny of Gardenieae (Rubiaceae) based on chloroplast DNA sequences from the rps16 intron and trnL(UAA)‐F(GAA) intergenic spacer

The results indicate that Gardenieae is polyphyletic and that genera included in the subtribe Diplosporinae should be transferred to the Coffeeae and Octotropideae.

Searching for the taxonomic position of the African genus Colletoecema (Rubiaceae): morphology and anatomy compared to an rps16-intron analysis of the Rubioideae

Morphological and anatomical comparison shows that Colletoecema differs in many aspects from the Psychotrieae (e.g., wood anatomy, seed structure).

Molecular Phylogenetics and Patterns of Floral Evolution in the Ericales

It is demonstrated that sympetaly is a homoplasious character in the order, that a diplostemonous floral ground plan likely arose from haplostemonic flowers in Ericales, and that the combination of ovules with a single integument and cellular endosperm formation is characteristic for two of the major clades in theOrder.
