Journal ArticleDOI
Evolutionary History of the Genus Pseudolarix Gordon (Pinaceae)
Ben A. LePage,James F. Basinger +1 more
TL;DR: The spatial and temporal distribution pattern of fossil Pseudolarix indicates that displacement between Eurasia and North America from the Late Jurassic/Early Cretaceous to the Plio-Pleistocene occurred through Beringia and the newly defined Spitsbergen Corridor; the North Atlantic routes were apparently not used by Pseud polarix.
Journal ArticleDOI
Phylogenetic interrelationships in the order Primulales, with special emphasis on the family circumscriptions
Arne A. Anderberg,Bertil Ståhl +1 more
TL;DR: Cladistic parsimony analyses indicate that the Primulaceae, Theophrastaceae, and Myrsinaceae (excluding Maesa) represent three major monophyletic groups.
Journal ArticleDOI
Phylogeny of the Ranunculaceae Based on Epidermal Microcharacters and Macromorphology
TL;DR: The epidermal microcharacters of 20 genera in the Ranunculaceae and 10 outgroup genera from the families Glaucidiaceae, Circaeasteraceae, Berberidaceae, Menispermaceae, and Lar- dizabalaceae were studied employing scanning electron and light microscopy to assess phylogeny in the family.
Journal ArticleDOI
Comparative floral structure and systematics in Celastrales (Celastraceae, Parnassiaceae, Lepidobotryaceae).
TL;DR: Among Celastrales, Lepidobotryaceae especially share special features with Malpighiales, including a diplostemonous androecium with ten fertile stamens, epitropous ovules with an obturator and strong vascularization around the chalaza.
Journal ArticleDOI
Liana structure, function and selection: a comparative study of xylem cylinders of tropical rainforest species in Africa and America
TL;DR: The American lianas show a distinct propensity to form a crown in the forest canopy constituted of multiple leafy units which grow apart with an increasing distance between each unit (expansion with a centrifugal tendency).
