Celebrating Visionaries in Bamboo Innovation

Currently, Dr. Clark serves as Director of the Ada Hayden Herbarium of Iowa State University and is a Professor and the Interim Chair of the Department of Ecology, Evolution and Organismal Biology (EEOB) at Iowa State University. She holds a Ph.D. in Botany, Iowa State University, (1986), B.S., Botany, Michigan State University (1979), and B.S., Horticulture, Michigan State University (1979).

Her area of expertise is in Plant Systematics and Evolution, and her research program involves four main lines of investigation: 1) bamboo systematics and evolution based on both morphological and molecular data; 2) floristic inventory and monography of Neotropical bamboos; 3) the evolution and development of vegetative features (e.g., leaf shape and 3-D leaf anatomy) within the grass family; and 4) functional trait ecology and evolution in fire-adapted Neotropical bamboos.

As director of Iowa State’s Ada Hayden Herbarium for 32 years, she oversees the herbarium’s 640,000 plant specimens—the 12th largest university collection of plants in the United States.

Today we honor Lynn as an expert in tropical woody bamboos, whose research and teaching have expanded our collective understanding of bamboos. As a high school student, Lynn worked summers with another World Bamboo Pioneer, grass expert Thomas Soderstrom at the National Museum of Natural History.

After earning her Ph.D. in botany from Iowa State in 1986, Clark was hired as a temporary assistant professor in the Department of Botany. At the time, her studies on bamboo and grasses were gaining traction in the research community. Today, Lynn is the world’s foremost expert on bamboo and its evolution. She’s named and published more than 130 new species of bamboo which she discovered in Brazil, Colombia, Ecuador, Mexico and elsewhere. A new grass that a former student identified in Mexico bears her name, Digitaria clarkiae. Lynn’s prowess has secured research grants from the National Science Foundation, the Brazilian government, the U.S. Department of Agriculture, the National Geographic Society and the Smithsonian Institution.

She’s also an accomplished scholar who has published 161 articles in professional journals. Her research, which is primarily focused on bamboo classification, bamboo evolution and grass phylogeny, has garnered more than 7,800 citations, and she has authored several books and chapters on grasses, bamboos, and native Iowa plants.

It’s hard for many people today to understand what it was like before the digital age when we only had hard copy books as references. However, a ground-breaking reference entitled American Bamboos was published in 1999 by Smithsonian Books, authored by Emmett J. Judziewicz, Lynn G. Clark, Ximena Londoño (World Bamboo Pioneer 2018), Margaret J. Stern. Drawing on two decades of fieldwork in the United States and fifteen Latin American countries, the authors brought together current knowledge of the structure, ecology, human uses, conservation value, evolution, and diversity of the forty-one genera of American woody and herbaceous bamboos. For many, it broke the image of bamboo as strictly an Asian plant.

During her time at Iowa State, Clark has served on numerous university committees, taught introductory and upper-level courses and has been a dedicated mentor to hundreds of undergraduate, graduate, and post-doc students. She’s earned numerous awards including the College of Liberal Arts and Sciences International Service Award and an Iowa State University Award for Outstanding Achievement in Research. She was selected as a Dean’s Lecturer in spring 2017. Most recently, she won a 2021 Regents Award for Faculty Excellence.

Within the bamboo community, most notably the American Bamboo Society and its Chapters, the Bamboo of the America’s project, the Colombian Bamboo Society, and the international Bamboo Phylogeny Group formed in 2005, and WBO, Lynn has been a constant consultant on all issues of taxonomy, nomenclature, and evolution of bamboos for decades. Members of the Bamboo Phylogeny Group include 20 researchers in 10 countries. Leaf material was collected from representative species of all tribes in the grass subfamily Bambusoideae (bamboos). DNA sequencing of 5 genetic loci in the bamboo chloroplast genome was used to compare mutations and estimate the first complete tribal and subtribal phylogeny of bamboos. Thanks to the efforts of the group, the analysis is notable for its species sampling, its rigorous testing of the estimate, and its robust results.

Lynn loves teaching, and anyone who has heard her present at a meeting or conference comes away knowing much more than they imagined. Thanks to much of Lynn’s efforts, the Bamboo Phylogeny Group used its estimate of bamboo relationships to produce a revised scientific classification for bamboos. The classification was presented at the 9th World Bamboo Congress in Antwerp, Belgium in April 2012.

Unfortunately, Lynn could not be with us today in Vietnam; she has far too much responsibility at the University at the beginning of the semester to join us. However, we are fortunate to have a recorded presentation by her for our program. Thank you, Lynn, for all your pioneering in the discovery of bamboo taxonomy, evolution and ecology. We are so grateful.
