I'm Steve Sullivan and I made this Website. I collected the data, organized it
and wrote the programs.
I obtained a BS degree in Math from Oregon State University before there was a computer science
degree. Then I worked for Tektronix for 35 years as a programmer, circuit board designer
and an integrated circuit designer. Now that I have retired, making a wildflower
identification website and Apps has become my hobby. I also enjoy taking wildflower
hikes with my wife, Yan, who enjoys photographing flowers with macro photography.
We formed Wildflower Search, an Oregon Not-for-profit Corporation that owns and
maintains the WildflowerSearch.org website and the
Free Wildflower Identification apps.

Matt Lavin is a professor of Plant Sciences & Plant Pathology at Montana State University.
He studies native and exotic plant diversity and teaches courses.
"The emphasis of my research is on the molecular systematics and biogeography of
the biodiverse legume plant family (Fabaceae or Leguminosae), including the cultivated species.
Because legumes are often most diverse in highly seasonal environments, I am interested in
the study of patterns of plant biodiversity across large landscapes of the North American
sagebrush steppe and adjacent desert regions, and Neotropical seasonally dry tropical forests
(those rich in succulent taxa such as Cactaceae and Euphorbiaceae) and adjacent tropical
savannas and wet forests."
Matt has posted about 19,000 botanical photos to Flickr for use in
teaching and to help him remember taxonomic-ecological-geographical points-in-time.

Thousands and thousands of Botanical Plant Collectors, over the last
hundred years, have collected millions of plant specimens that are now archived
in herbaria. Each collection is verified, then pressed and dried
and catalogued. Other people have converted these collections into digital
records which we use to deduce where and when species can be found.
We use over ten million of these collection records.
The search by location, elevation and time of year used in this
website is only possible because of the great amount of work done by the
botanical plant collectors and the herbarium staff. The many herbaria
involved in this work can be seen at this
