Leslie Roger Landrum (born 1946) is an American botanist serving as senior research scientist at Arizona State University School of Life Sciences, and curator of the ASU Vascular Plant Herbarium. He attained M.S. and Ph.D. degrees from the University of Michigan, and has been at Arizona State University since 1986. [1]
From 1969 to 1973, he worked with the Peace Corps at the Forestry School of the University of Chile, where he gained an interest in the flora of South America, particularly the myrtle family (Myrtaceae). Since then, he has published descriptions of new genera and species within the South American Myrtaceae, devoting particular study to the genus Psidium (which includes the commercially important guava).
Other concentrations include the Chilean species of the widespread genus Berberis , the usage of computer models in evaluating methods of phylogenetic analysis, and serving on a committee of botanists (including D.J. Pinkava) working on a new manual of the vascular plants of Arizona to replace the aging Arizona Flora by Kearney and Peebles (last updated in 1960).
He is on the editorial board of the Journal of The Arizona–Nevada Academy of Science, and since 2005, he has been the editor of Canotia: A New Journal of Arizona Botany.
Landum is one of the original scientists to participate in the Ask A Biologist program and the subject of the "Smashing Success" article detailing his work with ASU Vascular Plant Herbarium.
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous.
