Sherwin Carlquist – A Visionary Botanist and Plant Anatomist

Sherwin Carlquist (1930–2021) was a pioneering American botanist whose groundbreaking work in plant anatomy, island biology, and wood evolution impacted modern botanical science.

Over a prolific career spanning more than six decades, Carlquist published influential studies on xylem anatomy, plant adaptation, and the unique flora of island ecosystems—particularly in Hawaii and Australia. His work not only deepened our understanding of plant physiology and evolution but also illuminated how isolated environments drive biodiversity.

A professor, author, and Guggenheim Fellow, Carlquist was admired for his depth of knowledge, and rigorous scientific methodology. His legacy lives on through his extensive publications, scientific collections, and the generations of botanists he inspired.

In 2018, BRIT Library received Carlquist’s collection of archival materials related to his field expeditions. His biological specimens reside at the California Botanic Garden Herbarium (RSA) in Claremont, California.

The Sherwin Carlquist Collection

The Sherwin Carlquist Collection at BRIT Library comprises approximately 160,000 archival objects created by Carlquist from 1951 – 2012. They relate to his field expeditions, observations, and specimen collections from all over the world. The collection consists of field notebooks, color slides, black and white negatives and prints, and index envelopes. The bulk of the collection are the slides, focusing on aerial, landscape, habitat, habit, macro, and cross-section views of plants. However, non-botanical photographs capture Carlquist’s interest in architecture, cultural anthropology, ethnobotany, history, geography, design, and photography.

Sherwin Carlquist and the Extended Specimen Network

In 2022, BRIT and the California Botanic Garden were awarded a grant by the National Science Foundation to curate, preserve, digitize, and connect Carlquist’s biological and archival collections digitally within a framework known as the Extended Specimen Network (ESN). By virtually joining the collections, the ESN aims to enhance the understanding of both for public access and research.

National Science Foundation award #2133562.
