James Emory Eckenwalder (born 1949 in Neuilly-sur-Seine) is a Canadian botanist. His scientific work deals with the taxonomy, hybridization, and evolution of trees. His official botanical author abbreviation is Eckenw. [1]
James Eckenwalder was born in Neuilly-sur-Seine in France in 1949. He studied at Reed College in Portland, Oregon, where he graduated with a BA in 1971. He completed his doctoral thesis Systematics of Populus L. (Salicaceae) in southwestern North America with special reference to sect. Aigeros Duby at the University of California at Berkeley and obtained his Ph.D. in 1977. During this time he was a research assistant at the Jepson Herbarium. He started his university career at the Fairchild Tropical Garden Research Center in Miami, Florida, but after just one year he moved to the University of Toronto as an assistant professor. Since 1979, he has also been a research fellow at the Royal Ontario Museum. In 1985, he became an associate professor in the Department of Botany at the University of Toronto. [3] Following departmental reorganizations, he became a member of the Department of Ecology and Evolutionary Biology, from which he retired as Associate Professor emeritus in 2017.
Eckenwalder is an expert in the taxonomy of poplars (Populus). Further areas of interest are cycads (Cycadales), conifers (Coniferales), morning glories (Convolvulaceae) and water hyacinth relatives (Pontederiaceae). [3] His scientific work focuses on taxonomy, the formation of natural hybrids, paleobotany, and evolution, some of which led to significant changes in the taxonomy of conifers. [4] His field studies have taken him to vast areas of the United States and Canada, the West Indies, Central America, South America, and Europe. [3]

The order Pinales in the division Pinophyta, class Pinopsida, comprises all the extant conifers. The distinguishing characteristic is the reproductive structure known as a cone produced by all Pinales. All of the extant conifers, such as Araucaria, cedar, celery-pine, cypress, fir, juniper, kauri, larch, pine, redwood, spruce, and yew, are included here. Some fossil conifers, however, belong to other distinct orders within the division Pinophyta.
Taxodium is a genus of one to three species of extremely flood-tolerant conifers in the cypress family, Cupressaceae. The name is derived from the Latin word taxus, meaning "yew", and the Greek word εἶδος (eidos), meaning "similar to." Within the family, Taxodium is most closely related to Chinese swamp cypress and sugi.
Neuilly-sur-Seine, also known simply as Neuilly, is an urban commune in the Hauts-de-Seine department just west of Paris in France. Immediately adjacent to the city, north of the Bois de Boulogne, the area is composed of mostly select residential neighbourhoods, as well as many corporate headquarters and a handful of foreign embassies. One of the most affluent areas of France, it is the wealthiest and most expensive suburb of Paris.
Podocarpaceae is a large family of mainly Southern Hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs. It contains 19 genera if Phyllocladus is included and Manoao and Sundacarpus are recognized. The family achieved its maximum diversity in the Cenozoic, making the Podocarpaceae family one of the most diverse in the southern hemisphere.
Halocarpus is a genus of conifers of the family Podocarpaceae. The genus includes three closely related species of evergreen trees and shrubs, all endemic to New Zealand.
Paul Arnold Fryxell was an American botanist known for his work on flowering plants, especially those within the Malvaceae.
Randall James Bayer is an American systematic botanist born in Buffalo, New York, who spent his childhood in East Aurora. He earned a B.Sc. with major in plant breeding and minor in horticulture in 1978 from Cornell University; an M.Sc. in systematic botany in 1980 from the Ohio State University; and a Ph.D. in 1984 from the Ohio State University with the dissertation Evolutionary Investigations in Antennaria. His interest in the genus Antennaria was inspired by noted evolutionary botanist George Ledyard Stebbins (1906–2000) who was a visiting professor at the Ohio State University in 1978–1979.

Christopher Nigel Page (1942–2022) was an English botanist who specialised in Ferns and Spermatophytes. He also worked on conifers, naming species of Afrocarpus, for example Afrocarpus dawei and Afrocarpus gracilior, Sundacarpus and Retrophyllum. He read botany at Durham University then gained a PhD at Newcastle University, followed by a post-doctoral fellowship from 1968 to 1970 at the University of Queensland, in Brisbane, working on Queensland pteridophytes, before returning to the UK to work at Oxford University for a year. In 1971 he became a Fellow of the Linnean Society and that same year he joined the Royal Botanic Garden Edinburgh (RBGE), founding the RGBE Conifer Conservation Programme, now The International Conifer Conservation Programme. In 1976-77 he visited eastern Australia to work on pteridophytes and also Japan, Taiwan, Hong Kong, The Philippines and New Zealand. He retired from the RBGE in 1996, moving to live in Cornwall. He joined Camborne School of Mines, University of Exeter, in 2004, teaching part-time on the Environmental Science and Technology degree in CSM, and also in Biosciences until 2008. Some of his research in Cornwall involved experiments in regreening former extractive minerals sites, which he presented in 2017 in Parliament, with Professor Hylke Glass, also of CSM, as co-author. He had given a talk on BBC4 in 2008 in the series "Meetings with Remarkable Trees" on monkey puzzles. He retired, as Senior Honorary Research Fellow, in June 2022.
