Premise of research. Paleoochna tiffneyi gen. et sp. nov. is described from late Paleocene fossil fruits from Almont (Morton County) and Beicegel Creek (McKenzie County), North Dakota. On the basis of distinctive anatomical and morphological features, these fruits demonstrate strong taxonomic affinities to Ochna and other members of the family Ochnaceae but are distinct at the generic level. Methodology. Fossil fruits were studied with a combination of transmitted and reflected light microscopy…

The mid-Paleocene fruit and seed flora from the Fort Union Formation of Newell’s Nook, southeastern Montana, USA

The middle Paleocene Newell’s Nook biota of the Tongue River Member of the Fort Union Formation, southeastern Montana, is best known for its early Tiffanian mammalian fauna. Here, we describe an…

The Paleocene–Eocene Thermal Maximum: Plants as Paleothermometers, Rain Gauges, and Monitors

We travel back in time through this chapter and take a field trip to western North America during the Paleocene– Eocene Thermal Maximum (PETM), some 56 million years ago. Here, plant-and-animal…

Water supply and demand remain coordinated during breakdown of the global scaling relationship between leaf size and major vein density.

This study demonstrates that shortening the major vein-stomata distance is economically not less advantageous than by increasing minor vein density, as illustrated by the same degree of coordination between vein and stomatal densities and the similar construction costs across networks with dense 2° veins and those with 'normally' spaced 2° vein.

Palynoflora of the Late Paleocene Silicified Shale at Almont, North Dakota, USA

A pollen and spore assemblage of 50 species was recovered from the late Paleocene (pollen zone P5) Almont locality in the Williston Basin, central North Dakota, USA. This palynoflora was extracted…

Palaeocarpinus dakotensis sp.n. (Betulaceae: Coryloideae) and Associated Staminate Catkins, Pollen, and Leaves from the Paleocene of North Dakota

Characters that were previously unknown for the genus are described from anatomically preserved specimens, supporting earlier suggestions that Palaeocarpinus combines features found separately in the extant Coryleae and Carpineae.

An Extinct Genus with Affinities to Extant Davidia and Camptotheca (Cornales) from the Paleocene of North America and Eastern Asia

A new genus of Cornales is recognized based on infructescences and foliage from the Paleocene of Wyoming, Montana, and North Dakota in the United States; southern Alberta, Canada; Heilongjiang,…

EARLY EOCENE MACROFLORA FROM THE RED HOT TRUCK STOP LOCALITY ( MERIDIAN , MISSISSIPPI , USA )

The U.S. Gulf Coast has an extensive but poorly dated paleobotanical record. A fossil locality behind the former Red Hot Truck Stop in Meridian, Mississippi, is wellknown for its unusually rich biota…

Tertiary Ginkgo Ovulate Organs with Associated Leaves from North Dakota, U.S.A., and Their Evolutionary Significance

Ginkgo cranei is the only Tertiary species of the genus described in which the ovulate organs are studied in some detail and corroborates the hypothesis that modern Ginkgo evolved from its ancestors by reduction and is helpful to classify Cenozoic ginks in a natural system.

Reproductive ecology of invasive Ochna serrulata (Ochnaceae) in south-eastern Queensland

Germination occurred under all seed-processing treatments (with and without pulp, and figbird gut passage), suggesting that although frugivores are important for dispersal, they are not essential for germination.

Comparative floral structure and systematics in Ochnaceae s.l. (Ochnaceae, Quiinaceae and Medusagynaceae; Malpighiales)

The most strongly supported subclade of two of the three families in molecular analyses, Quiinaceae and Medusagynaceae, is also particularly well supported by floral structural features, including the presence of functionally and morphologically unisexual flowers.

Phylogenetics of Quiinaceae (Malpighiales): evidence from trnL-trnF sequence data and morphology

Optising characters of breeding system onto the molecular phylogeny reveals that bisexual flowers (Froesia) are the ancestral state in Quiinaceae, whereas androdioecy (Quiina, Touroulia) and dioecY (Lacunaria) are derived breeding systems.

The morphology and relationships ofMedusagyne (Medusagynaceae)

The totality of morphological and anatomical evidence confirms the view that Medusagyne is a very distinct and evolutionarily isolated genus, best treated as forming the monotypic familyMedusagynaceae.

Notes on the taxonomy and distribution of the Ochnaceae in the Greater Antilles

In the Greater Antilles the family Ochnaceae is represented by the genera Sauvagesia and Ouratea, which comprises O. laurifolia, O. jamaicensis and O. elegans, all endemic to Jamaica.
