Plant Checklist for the Rocky Mountain National Park
Websites - All Regions
• PhytoImages. Maintained by Daniel Nickrent (Southern Illinois University Carbondale), photos and metadata are provided for over 120,000 images of plants worldwide.
Maintained by Kevin Nixon (Cornell University), this DOL website is the
software "mother ship" for PhytoImages and contains over 48,000 images
This is a comprehensive website (Plants Database) maintained by the
Natural Resources Conservation Service of the USDA. It provides
nomenclatural information, distribution maps, and photos of all plants
known from North America.
• Wildflower Identification Website. This site by Steven Sullivan is really quite amazing! Lots of information is then available for each plant including distribution maps, phenology, habitat type, etc. A very useful site for wildflowers (no grasses and sedges!) for all regions of North America. One can select the "Parks and Trails" button on the left, and then navigate to Colorado and click on the link to Rocky Mt. National Park.
of the United States. 2206 photographs of 616 wildflower species.
Colorado Plant Websites
• Colorado Rocky Mountain Wildflowers. This app is for your cell phone. It features many of the commonly seen wildflowers in this region. I have it and find it very useful!
Rocky Mountain National Park. This series of pages, hosted by the
National Park Service, provides photos and basic descriptions for algae,
lichens, mosses & liverworts, trees & shrubs and wildflowers of
Colorado Wildflowers. Includes 525 plant species growing east of
the Continental divide.
Wildflowers. For the nonspecialist, plants arranged by flower
of Magnolia. Although it is intended for non-botanists, the site
contains photos of trees, shrubs and wildflowers present in the Magnolia
district near Boulder Colorado. Site maintained by Jennifer Stewart.
a flora: the story of Jennifer Ackerfield by Mo Ewing. Published
in 2015, "Flora of Colorado" (Brit Press) is 818 pages long and covers
3,322 taxa. This flora is a remarkable accomplishment for many
reasons, as described on this web page. Click HERE

Useful Websites from Other States
• Wildflowers, Ferns, & Trees of Colorado, New Mexico, Arizona, & Utah. A very useful website that allows one to identify a plant based on morphological features as well as flowering time, vegetation zone, habitat, etc.
Plants of the Gilia Wilderness. By Russ Kleinman from the Dale
Zimmerman Herbarium. Information on 1100 of the ca. 1500 plant species
that grow in the Gila National Forest of southwestern New Mexico.
Field Guides. Has lots of information (descriptions, photos, maps,
etc.) on not just plants but fungi, lichens, and animals.
Wildflowers and Grasses. This site contains information on nearly
900 species of forbs, grasses, sedges, rushes, trees, and other woody
plants found growing in Kansas. Most photos by Mike Haddock.
• Minnesota Wildflowers. A superb website with fantastic photography (many photos labeled). Some overlap with the flora of Colorado.
Texas Plants. A compilation of photos taken as part of "Native
Plants of Central Texas" course at University of Texas, the site is
maintained by Katie Hansen.
of Eastern Washington and Adjacent Idaho. Beautiful plant
photography presented by Robert L. Carr and Gerald D. Carr.
• Grasses of Iowa. Many of the grasses found in Iowa are the same as seen in Colorado, so this site is useful for identification.
• The Grass Manual. The treatment of grasses for Flora North America used to be up and running, but as this web page explains, it will be unavailable for several months while the site is improved and rebuilt. I can't wait until it is back in operation!
• The Sedge Family East of the Cascade Mountains of Oregon and Washington. With sedges (particularly Carex), one needs all the help available to get an accurate identification. Although distant from Colorado, there is some overlap in these species from the Pacific northwest.
Mountain Herbarium. University of Wyoming, Laramie.
• SEINet: Arizona - New Mexico Chapter. This data portal covers plants in those two states, but many of these are also found in Colorado. Under "Flora Projects", there is one for the Colorado Plateau. Tina Ayers, Susan Holiday, and Glenn Rink have assembled a number of research checklists of plants that are quite useful. The plant names are hyperlinked to the relevant species pages. Those pages have photos (living plants and herbarium specimens), descriptions, and distribution maps.
• Colorado State University. Charles Maurer Herbarium Collection, College of Natural Sciences, Ft. Collins.
Section & University Herbarium (COLO), Museum of Natural
History, University of Colorado Boulder. Includes database
and research tools such as the Catalog of the Colorado Flora and
Colorado Vascular Plants by County.
College Herbarium. This page contains links to the pdf files of
the work entitled "Peak to Prairie" by Tass Kelso. This describes the
flora of El Paso, Pueblo, Teller, and Fremont counties including Pikes
Peak. The specimens collected for the Pikes Peak flora can be accessed
(Southeast Regional Network of Expertise and Collections).
