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… 

Fossil Records in the Lythraceae

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.

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 the

Early Eocene Spore and Pollen Assemblages from the Laguna del Hunco Fossil Lake Beds, Patagonia, Argentina

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.

Amphistemon and Thamnoldenlandia, two new genera of Rubiaceae (Spermacoceae) endemic to Madagascar

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.

Role of the Qinghai-Tibetan Plateau uplift in the Northern Hemisphere disjunction: evidence from two herbaceous genera of Rubiaceae

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.

Studies in Neotropical paleobotany. XII. A palynoflorafrom the Pliocene Rio Banano Formation of Costa Rica and the Neogenevegetation of Mesoamerica.

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.

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 purpose of the present work is to review the Paleogene taphofloras of South America and to analyze their paleophytogeographical and paleoclimatical significance, and to agree on the terminology used in biogeographical discussions, especially among paleobotanists.

Fossil pollen records of extant angiosperms

The fossil record for angiosperm pollen types which are comparable to recent taxa is evaluated, following a similar survey published in 1970. Special attention is paid to the dating of the sediments.

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.

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.
