Your wildflower search engine.

Search for wildflowers by location, color, flower shape, flower size and time of blooming. 3,126 plants indexed. This web site helps those of us with limited knowledge of botany to identify flowering plants that are found outside of gardens. This help is provided by presenting you with small images of plants. You can use a number of search techniques to get to the images that are most likely the plant you are looking for. When you click on a plant image the program shows you links to plant descriptions and more plant images. The site has about 5 ways of searching for a plant. You can use these searches in any combination. Some searches eliminate some plants from consideration. Most searches give a "score" to each plant depending on how well the plant matches the search criteria. The plants with the highest score are displayed at the top of the results.

Time Tree

TimeTree is a public knowledge-base for information on the evolutionary timescale of life. A search utility allows exploration of the thousands of divergence times among organisms in the published literature. A tree-based (hierarchical) system is used to identify all published molecular time estimates bearing on the divergence of two chosen taxa, such as species, compute summary statistics, and present the results . . . For those interested in published summaries of relationships and divergence times of major groups of organisms (family level and above), see the authoritative synthesis The Timetree of Life.

Here are some examples to get you started: Humans and Chimpanzees diverged 6.3 MYA; Giraffes and Dolphins diverged 58.3 MYA; Cats and Mice diverged 95.2 MYA; and Dogs and Fleas diverged 777.8 MYA. [more inside]

What Is A Species?

What Is A Species? "To this day, scientists struggle with that question. A better definition can influence which animals make the endangered list."
