Dogwoods evolved in two main lineages, a red-fruited line in which the inflorescences have basal bracts, and a blue-(or white-)fruited line in which the bracts are rudimentary or lacking. The 15 “red-line” species are mostly well marked, whereas “blue-line” species—numbering roughly 50 if some newer treatments be accepted—are mostly hard to tell apart. Red-line ovules are tenuinucellate, blue-line ovules crassinucellate. Dividing the red line separates cornelian cherries from the showy-bracted… Expand

Systematics and Leaf Architecture of the Gunneraceae
Cladistic and phenetic analyses of leaf and other morphological characters ofGunnera strongly support monophyly of the genus, with the Saxifragaceae s.str. as the closest sister group. ThisExpand
Homologous Fruit Characters in Geographically Separated Genera of Extant and Fossil Torricelliaceae (Apiales)
TLDR
This work shows that the fruits of these three genera are distinctive in their morphology and anatomy, allowing for identification of fossils to the generic level, and supports the previous recognition of Torricellia from themiddle Eocene of North America and from the middle Eocene to middle Miocene of Europe.

Anatomically preserved fossil cornalean fruits from the Upper Cretaceous of Hokkaido: Eydeia hokkaidoensis gen. et sp. nov.
TLDR
A new taxon of Cornales is described, Eydeia hokkaidoensis gen. et sp. Expand
The classification and geography of the flowering plants: Dicotyledons of the class Angiospermae
  • R. Thorne
  • Geography, Biology
  • The Botanical Review
  • 2008
TLDR
This latest revision of the classification and geography of the Dicotyledons is necessitated by the plethora of new information that has become available about the classification of the Angiospermae, especially in the currently popular approaches of cladistic, particulate, and molecular taxonomy. Expand
Floral morphology and morphogenesis in Camptotheca (Nyssaceae), and its systematic significance
TLDR
Inflorescence and floral characters support a close relationship with Nyssaceae and Mastixiaceae but a distant relationship with Cornus, and corroborate molecular inferences and support a separate family NySSaceae. Expand
Leaves of Cornus (Cornaceae) from the Paleocene of North America and Asia Confirmed by Trichome Characters
TLDR
Reexamination of previously described Cornus leaves from the Paleocene of the Rocky Mountains and Great Plains region leads us to reject Cornus nebrascensis Schimper (=Cornus newberryi Hollick) from the genus, and recognizes two new Paleocene species, whose identity as Cornus is confirmed by the presence of characteristic trichomes and venation. Expand
Cornalean affinities, phylogenetic significance, and biogeographic implications of Operculifructus infructescences from the Late Cretaceous (Campanian) of Mexico.
TLDR
Operculifructus provides direct evidence for the occurrence of Grubbiaceae in the Late Cretaceous, much older than previous Eocene evidence. Expand
Cryptic Dioecy in Nyssa Yunnanensis (Nyssaceae), A Critically Endangered Species from Tropical Eastern Asia1
TLDR
The 37 known trees of N. yunnanensis are likely the remnants of a once more widespread, abundant species that has been heavily impacted by human disturbance, a fate shared with many other threatened Southeast Asian taxa whose continued survival will require dedicated conservation efforts informed by a detailed understanding of population structure and reproductive biology.

Curtisia (Cornales) from the Eocene of Europe and its phytogeographical significance
TLDR
The newly recognized fossil occurrences suggest a Laurasian origin for Curtisia, in conformity with the fossil record for several other genera of the Cornales, and cause us to question whether Epacridaceae were present in the Tertiary of Europe. Expand

Analysis of floral structure in all onagraceous genera-with Lopezia and Ludwigia studied most intensively-indicates that the earliest onagrads were isomerous and diplostemonous and had more than fourExpand
The case for keeping Cornus in the broad Linnaean sense
TLDR
Today, in eastern Europe and in Asia, steadfast splitters view all those as genera-Cornus sensu stricto, Swida, Chamaepericlymenum, Cynoxylon-and make four more from dogwoods that Linnaeus did not know-Afrocrania, Bothrocaryum, Dendrobenthamia, Discocrania-and there are the following reasons for retaining Cornus in its broad sense.

INFERIOR OVARY AND GENERIC AFFINITIES OF GARRYA
TLDR
In gynoecial characters Garrya most closely resembles Griselinia and, to a lesser extent, Aucuba, and these 3 genera probably had a common origin within the Cornaceae. Expand
THE SYSTEMATICS AND ANATOMY OF GONGYLOCARPUS (ONAGRACEAE)
TLDR
The degree of relationship between these two habitally very distinct species is determined in the light of a comparative anatomical investigation; their position within the family Onagraceae is investigated; and a description of the ontogeny of their bizarre fruiting structures is provided. Expand
DEVELOPMENT OF THE EPIPHYLLOUS INFLORESCENCE OF HELWINGIA JAPONICA (HELWINGIACEAE)
TLDR
It is argued that the vascular -anatomy does not conclusively confirm the hypothesis that the epiphyllous inflorescence is the congenital fusion product of a leaf and an axillary inflorescence, and it is suggested that the interplay of changes in the position of primordium initiation, and intercalary growth, offers an ontogenetic explanation of the situation.

Flower Associations of Mimetic Syrphidae (Diptera) in Northern Michigan
TLDR
The data from northern Michigan presented here concern a group of little studied, high fidelity mimetic Syrphidae that are particularly numerous in the ecotone between the boreal and deciduous forests. Expand

TLDR
The nucellus of Aucuba, in the formation of a definite layer of parietal tissue, a small epidermal cap, and in subsequent bulk-extension owing to cell-division, approaches the type described by Pechoutre for the Rosaceae. Expand
A revision of the genus Mastixia (Cornaceae)
TLDR
A revision of the genus in its entire range of distribution is presented, and two new subgenera, Manglesia Matthew (2 species) and Mastixia (II species) are established, based on the arrangement of the first order branches of the inflorescence. Expand
Systematic anatomy of Oceanopapaver, a monotypic genus of the Capparaceae from New Caledonia
TLDR
Evidence from vegetative anatomy, reproductive morphology, and palynology does not support a relationship of Oceanopapaver with Cistaceae, Cruciferae, Flacourtiaceae, Papaveraceae, and Tiliaceae, but suggests placement of the genus in Capparaceae, while the phylogenetic and functional anatomy of vegetative and reproductive structures is discussed.

General aspects of angiosperm evolution and macrosystematics
TLDR
It is concluded that pleiomerous flowers with helically arranged parts (corresponding to the Magnolia type, though probably less elaborate), on the basis of recent evidence can still be regarded as the probably earliest floral type in angiosperms. Expand
