Steve and Yan

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.


Patrick Alexander

"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 14,000 botanical photos to Flickr for use in teaching and to help him remember taxonomic-ecological-geographical points-in-time. Thank you, Matt, for allowing others to use your photos.

Uli Lorimer

Uli Lorimer is the curator of the Native Flora Garden in the Brooklyn Botanic Garden. He has had a passion for wildflowers and anything green since he was a boy. Photography came later on in his career as a way to document what was going on in the garden as well as in his field work.

The team leader is John Seiler, Distinguished Professor of Forestry. Happily, their photo use policy allows their photos to be used in nonprofit uses such as this website.


Thousand Photographers

More than a Thousand Image Authors have contributed to this website, so many that they can not all be listed here. But every one of them is appreciated. Most often they have posted their photos with a Creative Commons license. Some have made their photos public domain. Others have given us their permission to use their photos.

You can see their names and the number of photos that have been contributed on the Image Authors page. Thank you for taking great botanical photos, for identifying the species, for posting your photos on the web and for giving us permission to use them.


Botanical Collectors

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 Attribution and Copyright link. Thank you, collectors and herbarium staff, for the work that you do.
