Tina Ayers, Ph.D
Tina’s interests are in plant
systematics, biogeography, and floristics; she teaches graduate courses in all
of these topics and a course in plant systematics is offered at the
Currently, Tina is completing
a monograph of the genus Lysipomia
(Campanulaceae), a genus of about 40 species endemic to the Andean alpine
tundra. Additional projects include a molecular phylogenetic analysis of Nemacladus, which is being done in collaboration
with Dr. Nancy Morin; systematics of Cyphocarpus;
and systematics of Lobelia in Mexico
and Central America. All of these studies involve gathering molecular sequence
data from chloroplast or nuclear genomes and collecting macro- and
micromorphological data. Tina is also interested in rare plant conservation and
florisitics, especially in the southwestern United States and northern Mexico.

became a volunteer for the Deaver Herbarium after retiring from the U.S. Forest
Service, where he worked for 28 years, including 21 years with the Coconino
National Forest. Greg is in the herbarium a few mornings per week processing
historical collections donated by the U.S. Forest Service or processing his own
collections from travels throughout the West. Greg is also compiling a
floristic inventory of the Cataract Canyon drainage. This effort includes
surveying for rare plants.
Max Licher, Architect
Max is one of the coordinating
botanists for the Plant Atlas of Arizona Project (PAPAZ) and an avid
photographer. He has contributed many images to the Southwest Environmental Information Network, or SEINet, database. Max has been working on an annotated checklist of the
plants of Oak Creek Canyon and the Red Rocks area of the Verde Valley, Arizona.
He is also currently working in collaboration with Glenn Rink on a revision of Carex for Arizona
the latest vascular plant manual for Arizona.
Gisela Kluwin, P.T.,
Vera Markgraf, Ph.D.
Gisela and Vera are major contributors to the Plant Atlas of Arizona Project
(PAPAZ) and process all of their specimens in the Deaver Herbarium. When
they aren't off collecting or processing specimens, they are busy mounting,
accessioning, and filing specimens.

question, Glenn is out in the field collecting plants for various agencies or
just for fun on most days. He is currently documenting flora in southern
Colorado Plateau area, focusing especially on the Kaibab Plateau. Glenn is also currently collaborating with Max Licher on a revision of Carex

Randy Scott, Ph.D.
currently working on a monograph of the genus Brickellia (Asteraceae), a genus of 90 to 100 species found
primarily in the southwestern United States and western Mexico. He also lends a
hand wherever he is needed at the herbarium, including identifying many of the
unknown Asteraceae the herbarium receives, filing newly mounted specimens, giving
tours, and whatever else comes up.

John Spence, Ph.D.
John Spence, who
lives in Page, Arizona, is the botanist for Glen Canyon National Recreation
Area. He regularly visits the Deaver Herbarium to work on specimens from around
the world that have been loaned to the herbarium. John’s interests are wide
ranging and include the biogeography and evolution of Colorado Plateau flora,
especially endemic and rare species; vegetation ecology and classification;
bryophyte and vascular plant systematics; bird inventory, monitoring, and
ecology; and ecological effects of climate change. View more information about John’s interests and publications and
