Patuxent Plant List and Herbarium Collection
Entry ID: PWRC_Herbarium


Summary
Abstract: The herbarium presently contains over a thousand collections of pressed, dried
plant specimens that were gathered on the refuge during early plant surveys
undertaken after the creation of the refuge. The first preliminary plant survey
was conducted by Neil Hotchkiss and Robert E. Stewart during the years
1936-1946. At that time the refuge was approximately 2600 acres in size.

In 1979, William H. Stickel republished the original list, which included an
addendum of plants on the refuge that were not listed in the earlier survey.
The following lists represent the plants from the two previous reports, and at
least 25 new plants not previously reported. All plants have received updated
taxonomy and are arranged in phylogenetic order (alphabetic within genera).

It is recognized that some species on this list may no longer occur on the
refuge. Many plants from other parts of the country were introduced to Patuxent
Research Refuge during the early decades. These introductions include wetland
plants for the waterfowl impoundment studies, and upland plants, for the farm
game management program. Those that have been identified during the 1980's and
1990's are identified in bold type. Plants that have specimens in the herbarium
are indicated by the date of the specimen. Plants marked by an asterisk are not
native to North America.

Plant specimens have been added periodically to the collection by the staff and
the herbarium is maintained with the assistance of a staff of volunteers. The
herbarium offers an exceptional reference collection of plants occurring in the
area lying between Baltimore, Maryland, and Washington D.C.
