The Colorado Rare Plant Field Guide was produced over a three year period through
a cooperative effort involving many individuals and organizations.
The Bureau of Land Management, U.S. Forest Service, U.S. Fish and Wildlife Service,
the Colorado Natural Heritage Program and The Nature Conservancy provided funds
to produce the Colorado Rare Plant Field Guide. Funds for publication of the guide
were provided by the U.S. Forest Service; the Denver Botanic Gardens; the Natural
Resources Conservation Service; The Nature Conservancy; and the Colorado Natural
History Small Grants Program, made possible by the Colorado Natural Areas Program
and the Great Outdoors Colorado Trust Fund. Additional sponsors are listed on the
following page. Sheri Morris and Tamera Hammack with the Bureau of Land Management
in Cheyenne, Wyoming provided technical assistance in the prepress production of
Data gathered from herbaria in Colorado, Wyoming, Utah, Nebraska, and Oklahoma were
essential to the generation of accurate species accounts. We thank William Weber,
Thomas Ranker, and Timothy Hogan with the University of Colorado Herbarium; Ronald
Hartman and Ernie Nelson with the Rocky Mountain Herbarium; David Steingraber with
the Colorado State University Herbarium; Hobart Dixon with the Adams State College
Herbarium; Sylvia Kelso with the Colorado College Herbarium; Walter Kelley with
the Mesa State College Herbarium; William Harmon with the University of Northern
Colorado Herbarium; Neal Osborn with the University of Southern Colorado Herbarium;
David Jamieson with the Fort Lewis College Herbarium; Stanley Welsh, Kaye Thorne,
and Duane Atwood with the Brigham Young University Herbarium; Mary Barkworth and

We appreciate the input of our technical reviewers including Betsy Neely, Walter
Kelley, Janet Wingate, Tom Ranker, Gwen Kittel, John Sanderson, Julie Burt, Craig
Freeman, Ronald Hartman, Walter Fertig and Peter Root.
One of the great strengths of the guide is the depth of information provided through
the technical illustrations and photographs. Individual artists and photographers
are recognized throughout the text.

Rare Plant Field Guide.
Finally, the authors of the Colorado Rare Plant Field Guide would like to acknowledge
the following organizations for their commitment to rare flora research and conservation.
Their contributions towards printing costs helped ensure that copies of this Field
Guide could be found in any office, field vehicle, classroom, or library.
We’ve added 84 new species profiles! See the “Updated Profile” column on the
Master List page.
Your contribution, no matter how small, will help us update the remaining profiles and add the
rest of our tracked species. Click here
