Abstract Fossils of 134 taxa attributed to the Rubiaceae are described or mentioned in 115 publications dating from 1850 and from deposits as old as the Cretaceous and Paleocene. Close scrutiny of these records indicates, however, that the oldest and most likely (accepted) representatives of the family are four genera, Emmenopterys Oliv. from the Middle Eocene of Oregon and Washington, U.S.A., Faramea Aubl. from the Late Eocene of Panama, and Guettarda L. (cf. as †Guettardidites; †= fossil… Expand
Fossil Records in the Lythraceae
TLDR
Diversification of the Lythraceae occurred primarily during two major periods of global temperature change, during the Paleocene-Eocene Thermal Maximum and from the middle Miocene forward when temperatures decreased markedly and seasonality and dry-adapted vegetation types became more prominent. Expand
Fossil Record and Age of the Asteridae
TLDR
The results suggest that the Asteridae dates back to at least the Turonian, Late Cretaceous and that by the Late Santonian-Early Campanian its four main clades were already represented in the fossil record. Expand
Assessing the Fossil Record of Asterids in the Context of Our Current Phylogenetic Framework1
Abstract The fossil record provides good evidence for the minimum ages of important events in the diversification and geographic spread of Asteridae, with earliest examples extending back to theExpand
Paleobotanical remains from the Paleocene–lower Eocene Vagadkhol Formation, western India and their paleoclimatic and phytogeographic implications
TLDR
The wood and leaf taxa in the fossil assemblage are suggestive of tropical moist or wet forest with some deciduousness during the Paleocene–early Eocene, and the presence of many fungal taxa further suggests the prevalence of enough humidity at the time of sedimentation. Expand
Early Eocene Spore and Pollen Assemblages from the Laguna del Hunco Fossil Lake Beds, Patagonia, Argentina
TLDR
The LH spore-pollen assemblages augment the plant fossil record for this significant Eocene locality by incorporating new taxa, and reinforce the presence of plant families previously reported from macrofossils, such as Juglandaceae, with pollen grains similar to those of the Engelhardia-Alfaroa group. Expand
Amphistemon and Thamnoldenlandia, two new genera of Rubiaceae (Spermacoceae) endemic to Madagascar
TLDR
A molecular phylogenetic study indicates that the Madagascan endemic members of Spermacoceae are the result of at least two independent colonization events, most likely by long-distance dispersal from the African mainland. Expand
Dispersing towards Madagascar: Biogeography and evolution of the Madagascan endemics of the Spermacoceae tribe (Rubiaceae).
TLDR
Interestingly, not only colonization from Africa occurred but also long distance dispersal from the Neotropics shaped the current diversity of the Spermacoceae tribe on Madagascar. Expand
New Caledonian lineages of Psychotria (Rubiaceae) reveal different evolutionary histories and the largest documented plant radiation for the archipelago.
TLDR
Results show that New Caledonia was colonized four times by Psychotria and its allied genera during the Neogene long after its mid-Eocene re-emergence from the sea. Expand

Role of the Qinghai-Tibetan Plateau uplift in the Northern Hemisphere disjunction: evidence from two herbaceous genera of Rubiaceae
TLDR
The Qinghai-Tibetan Plateau separated the eastern and western Tethyan area may contribute significantly to the disjunct distributions of Theligonum, and the North Atlantic migration appears to be the most likely pathway of expansion of Kelloggia to North America. Expand

Studies in Neotropical paleobotany. XII. A palynoflorafrom the Pliocene Rio Banano Formation of Costa Rica and the Neogenevegetation of Mesoamerica.
TLDR
Data from the Pliocene Rio Banano Formation of southeastern Costa Rica are consistent with those from 12 other Miocene andPliocene palynofloras from northern Latin America, indicating the late appearance of dry habitats and moderate paleoelevations and a progressive southward introduction of northern temperate elements with late Cenozoic cooling.

Studies in Neotropical Paleobotany. XV. A Mio-Pliocene palynoflora from the Eastern Cordillera, Bolivia: implications for the uplift history of the Central Andes.
TLDR
When the total uplift is corrected for probable amounts of erosionally driven isostatic rebound, the paleoelevation estimate suggests that from one-third to one-half of the uplift of the Eastern Cordillera had occurred by the beginning of the Pliocene, consistent with other paleoeLevation estimates from the Central Andes.

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