In
1885, through a combination of funding from
the Harvard Botanical Museum and the Gray
Herbarium, Pringle was hired to begin
cataloging the plants of Mexico, because
little botanical work had ever been done
there. This work would continue over the next
26 years, years in which he ended up
botanizing 21 of the 27 states of Mexico. On
his trips to and from Mexico, Pringle always
made a point to take different routes; he was
thus able to further enrich his collections as
he passed through a diversity of terrains in
both the U.S. and Mexico.
By the time Pringle passed away in 1911, the botanical work he had done was astounding. He had distributed to various herbaria (including his own), some 500,000 sheets of about 20,000 species. These include 29 genera new to science, 1,200 new species, 100 new varieties, and 4 new combinations, more than almost any other collector. At the time of his death, Pringle Herbarium included approximately 155,000 sheets: a combination of his own collections and the rich diversity of materials he received in exchange. Among the institutions from which Pringle received exchange materials are the British Museum, Berlin, Kew Gardens, Edinburgh, Melbourne, Calcutta and also French, Swiss, Austrian and South African herbaria.
Ezra Brainerd Collection
(Middlebury College Herbarium):
Ezra
Brainerd, a past president of Middlebury
College, was a plant systematist specializing in
the difficult genera Cretaegus, Viola,
and Rubus. The vouchers for his
research on these genera, along with a
high-quality general herbarium from New England
and New York, formed the basis for the
Middlebury College Herbarium. In 1950,
Middlebury College transferred 3,000 sheets,
including all of Brainerd's collections and
about 100 types, to Pringle Herbarium.
Nellie F.
Flynn Collection (Goddard College
Herbarium): Nellie
Flynn was a prominent Vermont botanist and
author of a revision of The Flora of
Vermont; she was active in the early
1900s. She assembled an impressive collection
of plants from the Burlington, Vermont area,
and at the suggestion of L.R. Jones, wrote the
Flora of Burlington and Vicinity: A List of
the Fern and Seed Plants Growing Without
Cultivation.
She was an invested and productive plant
collector, documenting not only the local flora
but assembling collections from Massachusetts,
North and South Carolina, Virginia, Florida,
Canada, Cuba, the Bahamas, Switzerland, England,
France, Italy and Morocco. Her collections from
Nantucket, Massachusetts are among her largest
and serve as baseline information for
stewardship and systematic work on the Sand
Islands at the Wisconsin terminal moraine. In
1956, Pringle Herbarium acquired the Nellie
Flynn Herbarium holdings from Goddard College as
a permanent loan. This increased the holdings of
Pringle Herbarium by another 22,700 specimens.
Leopold
A. Charette Collection: Leopold Charette
served as assistant curator to Vogelmann and Seymour
from
the late 1950s through 1970. During his tenure, he
made substantial collections in Japan and China
(Pringle Herbarium holds ca. 5,300 of his sheets);
he also developed an exchange program to accession a
diverse set of additional plants from the same
region. Charette was equally important in the task
of making most of the sheets in Pringle Herbarium
accessible and available for study. Furthermore, we
are indebted to Mr. Charette for organizing the
voluminous Pringle archival materials.
Bates
College Herbarium: In 1981, Pringle Herbarium
purchased the herbarium collection from Bates
College (BCL), an acquisition of about 20,000
sheets (Index Herbariorum is incorrect). A
substantial portion of this collection has since
been integrated into Pringle Herbarium. The
Bates collection includes documentation of the
flora of Maine as well as apparent exchange
materials from the Gray Herbarium and the New
York Botanical Gardens. It also has strong
representation of the European flora.
William
Countryman Collection:
William Countryman
was a professional biologist with a broad
diversity of interests across the kingdoms of
living things. He ran both a botanical
consultant business and a horticultural
enterprise;
for many years, he specialized in peonies out of
his home in Northfield, Vermont. Bill was a
life-long collector; his personal herbarium of
about 15,000 sheets, with a strong regional
focus on Vermont and adjacent New York, was
donated to the Pringle Herbarium by his wife,
Anne, in 2006. The abundant duplicates in this
collection were distributed widely in exchange
in the following four years.

Peter F. Zika Collection: Peter Zika
received his undergraduate degree in botany at the
University of Vermont in 1983. He is currently a
botanist for the Bureau of Land Management in
Oregon. During his time as an undergraduate and in
the several years thereafter he made a substantial
investment in documenting and improving our
collections of the Vermont flora. His original
interest was in the alpine flora: he was the first
person since Pringle to certify the occurrence of
many of the rarer species at high altitudes in
Vermont. His interests broadened to include the
flora of the entire state, and working together with
Jerry Jenkins, a productive consultant systematist
here, has developed a high-quality checklist for the
flora of Vermont based on modern circumscription of
species. This work continues to be an interest of
Zika's in spite of his geographical separation from
us. There are some 7,500 sheets of mounted Zika
material at the herbarium and an additional 2,000
awaiting accession.
Steven R. Hill Collection: Dr.
Steven R. Hill is a botanist with the Illinois
Natural History Survey, with research interests
in the systematics of the Malvaceae, the flora
of Dominica and the Lesser Antilles, the
floristics of the eastern U.S. and the
threatened and endangered vascular plants of
Illinois. He has held several herbarium
positions, including Curator of the University
of Maryland (MARY) and Clemson University
(CLEMS) herbaria. Dr. Hill is an extraordinarily
active collector in an era of decreased emphasis
on documenting flora, with over 35,000 lifetime
numbers. He has chosen the Pringle Herbarium as
the permanent repository for The Hill Herbarium
(SRH), which has already led to adding
substantially (20,000+) to our New World
temperate and tropical holdings, with recent
high-quality documentation of the flora from
throughout the region. Dr. Hill has expressed a
desire to donate his extensive library and
remaining collections to our herbarium.
