RESEARCH INTERESTS

I am broadly interested in the following subjects:

• botanical bibliography, biography, and the history of botany
• the flora and vegetation of California and other mediterranean regions
• systematic anatomy and evolutionary morphology of the land plants (bryophytes and vascular plants)

My research thus involves these areas:

• botanical bibliography, biography, and the history of botany, especially of the period 1870-1945
• the flora and vegetation of California and adjacent areas, especially Baja California
• the flora and vegetation of New Caledonia
• conservation and threatened taxa, especially concerning gymnosperms
• systematic anatomy, including taxonomy, of anomalous taxa and sundry families such as Actinidiaceae, Burmanniaceae, Capparaceae, Labiatae, Pinaceae, Pyrolaceae, Scheuchzeriaceae, Triuridaceae, and especially Myrtaceae
• functional and comparative anatomy and morphology of wood, nectaries, flowers, fruits, and seeds, especially of their vascular systems

Doctoral research sponsored has included:

• Elizabeth Mary Lord (1978): The development and function of chasmogamy in Lamium amplexicaule
• Frank William Ewers (1982): Longevity and development of needles of Pinus longaeva (bristlecone pine) and other conifers
• Raymond Bruce Phillips (1982): Systematics of Parnassia L. (Parnassiaceae): Generic overview and revision of North American taxa
• Edward Kingsbury Merrill (1985): Heteroblastic seedlings of green ash [Fraxinus pennsylvanica var. subintegerrima]
• Larry Don Hufford (1986): Floral ontogeny and the divergence of reproductive morphologies in Eucnide (Loasaceae)
• Timothy Joseph Brady (1996): The significance of population successional status to the evolution of seedling morphology in lodgepole pine (Pinus contorta var. latifolia)
• Raymond Benton Cranfill (2001): Phylogenetic studies in the Polypodiales (Pteridophyta), with an emphasis on the family Blechnaceae
