Creator:: Zobel, Donald B. and Antos, Joseph A.
Abstract:: Premise of research. We sought to determine the role of flowering in recovery of understory herbs from a major disturbance and to determine the effects of plant and environmental factors on flowering patterns. Methodology. We counted flowering and nonflowering shoots in permanent plots eight to 10 times over a 30-year period for...

Creator:: Buczkowski, Emma L., Stockey, Ruth A., Atkinson, Brian A., and Rothwell, Gar W.
Abstract:: Premise of research. A large pollen cone cluster attached to a cunninghamioid twig and surrounded by leaves has been identified from Eocene calcium carbonate marine concretions from the Appian Way locality on Vancouver Island, British Columbia, Canada. The cluster preserves 18 cones but probably bore at least 24 pollen cones...

Abstract:: Premise of research. Twenty-one permineralized fossil flowers assignable to Lauraceae from the Eocene Appian Way locality on Vancouver Island, British Columbia, Canada, provide important anatomical and morphological data for interpreting evolutionary patterns in this diverse magnoliid family. Methodology. Consecutive anatomical sections were prepared using the cellulose acetate peel technique. Morphology...

Abstract:: Premise of research. A new, morphologically distinct, anatomically preserved conifer assignable to the basal Cupressaceae, which was subject to arthropod infestation during life, has been discovered within a marine carbonate concretion from the Coniacian (Late Cretaceous) Eden Main locality of Vancouver Island, British Columbia. Methods. Specimens were studied from anatomical...

Creator:: Smith, MacKenzie A., Rothwell, Gar W., and Stockey, Ruth A.
Abstract:: Premise of research: A distinctive new species of osmundaceous fern, based on a permineralized trunk from Lower Cretaceous deposits of Haida Gwaii (formerly the Queen Charlotte Islands) off the west coast of mainland Canada, provides additional data for addressing the Mesozoic diversity and the overall pattern of phylogeny for osmundaceous...

Creator:: Kelso, Sylvia, Beardsley, Paul M., and Weitemier, Kevin
Abstract:: Primula sect. Parryi comprises five species endemic to western North America: P. parryi, P. angustifolia, P. rusbyi, P. capillaris, and P. cusickiana with four varieties. This section, derived from a clade with representatives in Asia and Europe, exemplifies a phytogeographic pattern in which a widespread species is accompanied by multiple...

Creator:: Mindell, Randal A., Karafit, Steven J., and Stockey, Ruth A.
Abstract:: PREMISE OF RESEARCH: Anatomically preserved platanaceous inflorescences have been found in rocks of Late Cretaceous (Coniacian) age at the Eden Main locality on Vancouver Island, British Columbia, Canada. METHODOLOGY: Specimens occur in calcium carbonate concretions near the base of the Nanaimo Group (Comox Formation) and are studied with the cellulose...

Creator:: Atkinson, Brian A., Rothwell, Gar W., and Stockey, Ruth A.
Abstract:: PREMISE OF RESEARCH. The occurrence of six ovulate cones and six leafy branching systems, two of which show attachment of the ovulate cone, reveals a new cunninghamioid fossil conifer from the Cretaceous Apple Bay locality of Vancouver Island, Canada. This anatomically preserved plant expands our understanding of basal Cupressaceae in...

Creator:: Rothwell, Gar W., Mapes, Gene, Stockey, Ruth A., and Hilton, Jason
Abstract:: Premise of research. A third genus of anatomically preserved conifer seed cones has been recognized from a Late Jurassic deposit in northeastern Scotland. This cone is described as Bancroftiastrobus digitata Rothwell, Mapes, Stockey et Hilton. Methodology. The cone was sectioned with the classic coal ball peel technique and studied and...

Creator:: Smith, Selena Y., Little, Stefan A., Cooper, Ranessa L., Burnham, Robyn J., and Stockey, Ruth A.
Abstract:: Premise of research. The lianoid habit is found in 125 extant plant families and is most diverse and abundant in structurally complex forests, such as tropical forests. A stem with lianoid anatomy is described from Cretaceous sediments of Hornby Island, British Columbia. Methodology. The stem segment, 2.5 cm in diameter...
