Muir, Muir...In Our Halls

April 06, 2020

It was 1875, and John Muir was a busy man. He was already well-known for his journeys through central and northern California. His writing was published in newspapers and magazines around the country. But he still had time to help someone else.

A colleague, John Redfield, wrote to Muir asking for specimens to add to his collection. John Muir wrote back in May of 1875 and promised to collect in a few weeks. True to his word, Muir collected plant specimens in the Sierra Nevada mountain range and sent them to Redfield for study later that year. They continued to correspond about the collections and other scientific pursuits for the next few years.

John Muir went on to campaign for the protection of natural areas. He wrote several articles and a few books describing natural areas and the wonders they contain. His efforts resulted in the creation of Yosemite National Park in 1890. For this achievement, he has been called “The Father of our National Parks”. In 1892, he co-founded the Sierra Club, an environmental organization that works to conserve natural resources and encourage people’s enjoyment of them. In his later years, John Muir traveled the world, taking part in expeditions north to Alaska, south to Brazil and Chile, and east to Africa. He worked for the conservation and appreciation of nature until his death in 1914.

John Muir traveled extensively during his life, and the plants Muir collected went on a journey of their own. In 1875, the collections were sent to Redfield’s herbarium in Philadelphia. Twenty-two years later, in 1897, Redfield’s herbarium was purchased by Missouri Botanical Garden, and the plants were sent to St. Louis, Missouri. The collections stayed at Missouri for an unknown amount of time before they were sent to the Jesup Herbarium at Dartmouth College, probably in a shipment of specimens for exchange. The specimens stayed at Dartmouth College until 2002, when the Jesup Herbarium distributed a large portion of its holdings to other herbaria. BRIT received about 25,000 specimens from the Jesup Herbarium, these Muir fern specimens among them. That’s over 6,000 miles that these specimens traveled, a long way to go for plants that usually stay rooted in one spot! Since then, they have rested in our storage, undiscovered until recently, when a grant from the National Science Foundation gave us the ability to digitize our fern collection. This discovery underscores the importance of digitizing biocollections, as we can never completely know a collection until it is searchable in a database.

The Living Herbarium: A Life’s Work

Article originally published in the The Leaflet (November 2013) by Brian Witte, PhD, BRIT Research Associate Astragalus siliceus , Bob Hutchins 8787, Torrance Co. NM, May 1980 A herbarium can be as much a cabinet of mysteries as it is a repository of knowledge. Some mysteries are the results of quotidian clerical errors, simple misspellings, and the other inevitable vexations of managing a million-specimen collection. Some mysteries, however, are deeper and more gripping. In my year of volunteering and working with BRIT’s Philecology Herbarium, I have become consumed by one of the latter mysteries. My journey began, as many do, with a walk through the stacks, scanning the unofficial storage areas atop the cabinets, looking for boxes of specimens to prepare for mounting. It’s a little-known...

Nameless in the Living Herbarium

Article originally published in The Leaflet (March 2014) by Brian Witte, PhD, BRIT Research Associate Identifying a nameless specimen brings tremendous satisfaction. Naming seems simple. It’s just two words, after all. And yet, a world of stories is implicit in every name. Some of that story is explicit in the labels we affix to specimens: the when, where, and who of the moment it was collected. Much of the story, though, is implicit in the name of the plant. The two words of a scientific name, genus and species, refer to the place of the plant in 4 billion years of evolutionary history. Every species within a genus is, in theory, more closely related than to any species in any other genus. Likewise, all the genera grouped within a family are more closely related than to any genus in a dif...
