HANSEN, CURTIS J.*, CYNTHIA M. MORTON, and GLENDA GIL. Biological Sciences Department, Auburn University, Auburn, AL 36849. - Vascular plants of Alabama from the John D. Freeman Herbarium (AUA) and the University of Alabama Herbaria (ALU/UNA).
While evidence exists that the vascular flora of Alabama is very
diverse it remains poorly understood and catalogued. Of the 67
counties in Alabama only eleven have floras or checklists completed
and of those only one has been published. Much of the published
documentation regarding the flora of Alabama is focused only on
certain groups or regions, is taxonomically obsolete, or is no longer
in print and although there are several plant guides available, no
current statewide list of vascular plants exists for Alabama. The
Freeman Herbarium at Auburn University and the Herbaria at the
University of Alabama have joined efforts to compile a computerized
list of the vascular plants of Alabama based on the collective
holdings of both institutions. Other selected references were
consulted and included to supplement the data base information. This
information has provided us with an estimate of the total number of
families, genera and species found to occur in Alabama. We have
generated maps showing the numbers of genera and species collected in
each county. This information has been invaluable in identifying
severely under collected regions of the state and in targeting current
collecting activities. Also, a preliminary comparison of species
number to land area among southeastern states was performed and we
found further evidence that Alabama indeed has a rich and diverse
flora in need of further exploration and documentation. With
historical collections dating back to 1840, we are beginning to
examine how ecological and habitat diversity has changed over the last
century and a half. Efforts are also underway at the Freeman Herbarium
to create a "virtual herbarium" by making the data base
information along with digital images of specimens available on the
World Wide Web.
