Abstract

JSTOR is a not-for-profit service that helps scholars, researchers, and students discover, use, and build upon a wide range of content in a trusted digital archive. We use information technology and tools to increase productivity and facilitate new forms of scholarship. For more information about JSTOR, please contact support@jstor.org.. The University of Chicago Press is collaborating with JSTOR to digitize, preserve and extend access to International Journal of Plant Sciences.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, northeastern China; and Kamchatka and the Koryak Upland, northeastern Russia. Amersinia obtrullata gen. et sp. nov. has globose to ellipsoid infructescences with four or five basal deciduous bracts and numerous obtrullate, trilocular fruits with epigynous calyces. Each locule bears one seed and has a dorsal germination valve near the apex. The infructescences and fruits show many similarities to those of extant Camptotheca, but the extant genus is distinguished by only one or two locules and the absence of infructescence bracts. Fossil leaves previously assigned to "Viburnum" cupanioides (Newberry) Brown, Viburnum kingiensis Chelebaeva, and Viburnum pseudoantiquum Golovneva are transferred to the extinct foliage genus Beringiaphyllum gen. nov. They are distinguished from Viburnum by their long petioles and compare favorably to the leaves of extant Davidia. The fossil leaves are elliptical to ovate with pinnate secondary veins, percurrent tertiary veins, and obtuse teeth. Beringiaphyllum leaves and Amersinia fruits are considered likely to represent a single extinct genus because of their shared cornalean affinity and co-occurrence at numerous sites both in North America and Asia. Although the leaves share more characters with Davidia, the Amersinia fruits share more characters with Camptotheca. The existence of Amersinia and Beringiaphyllum both in Asia and North America, together with their absence or rarity in the Paleogene of Europe, indicates that this plant probably dispersed across Beringia in the late Cretaceous or early Tertiary.

Early diverging asterids of the Late Cretaceous:Suciacarpa starriigen. et sp. nov. and the initial radiation of Cornales

“…The fossil record of these families is extensive and is particularly well-documented by fruits (e.g., Reid and Chandler 1933;Eyde and Barghoorn 1963;Knobloch and Mai 1986;Eyde 1988Eyde , 1997Mai 1993;Tiffney and Haggard 1996;Stockey et al 1998;Manchester et al 1999Manchester et al , 2010Manchester et al , 2015Martinetto 2011). The general endocarp morphology observed in these families is also seen in Suciacarpa.…”

Monophyly and relationships of the tribe Exaceae (Gentianaceae) inferred from nuclear ribosomal and chloroplast DNA sequences

“…The Gentianaceae, or even the whole Gentianales, have so far not many reliable fossil records. The earliest fossil records for the basal clades of Asterids such as Cornales and Ericales are mostly from the Late Cretaceous (Turonian-Coniacian) of about 90 MY before present (Crepet, 1996;Crepet et al, 1992;Manchester, 2002;Manchester et al, 1999;Nixon and Crepet, 1993;Schonenberger and Friis, 2001;Takahashi et al, 1999). Archaefructus, supposed to be the earliest angiosperm fossil found so far, was 145 MY old (Sun et al, 1998).…”

Pollen, fruits, and leaves ofTetracentron(Trochodendraceae) from the Cainozoic of Iceland and western North America and their palaeobiogeographic implications

“…This Early Cainozoic biogeographical pattern is typical for a number of angiosperm taxa that are confined to East Asia today. Examples are Dipteronia (Sapindaceae, McClain & Manchester, 2001), Davidia (Manchester et al, 1999), Ulmus furcinervis (Borsuk) Ablaev sensu Feng et al (2003) and the closely related Ulmus okanaganense Denk & Dillhoff (Denk & Dilhoff, 2005). The Icelandic records of Tetracentron add to this pattern.…”
