"...the present volume is issued, not as Part II of Morphology of Spermatophytes, but as an independent volume entitled Morphology of Angiosperms; and any subsequent ...

Pollen morphology—the study of the size, shape, wall structure and aperture patterns of pollen grains—provides an essential window into the evolution and diversification of flowering plants. The outer ...

International Journal of Plant Sciences, Vol. 180, No. 2 (FEBRUARY 2019), pp. 93-127 (35 pages) Premise of research. Small angiosperm fossils are diverse in Early Cretaceous mesofossil floras from ...

Research interests include the comparative morphology and systematics of primitive dicotyledons and monocotyledons, comparative studies of pollen grains of living and fossil primitive angiosperms, ...

While reproductive evolution of flowering plants (angiosperms) is traditionally linked to the end-Cretaceous biotic crisis, new research suggests angiosperm dispersal ecologies had already diversified ...
