the Calflora Observer Pro Android phone application for collecting plant occurences in the field. His latest personal project is an Android word game experimenting with creating a multi-player experience from a single-player game. One can always play immediately, and it does away with the game timer to play well while watching television.

What is Calflora?
Calflora is 1. a website you can use to learn about
plants that grow wild in California (both native plants and weeds); and
2. a nonprofit organization responsible for the website.
Calflora is run by two paid staff members and a few volunteers.
Information in Calflora comes from many sources: public agencies, non-profits, scientists, private donors, and you!
Find Out About a Plant
You can enter the common or scientific name of a plant to find out about it. You can even use our new name wizard to just enter part of a name and have the wizard make suggestions. The result is an illustrated table of plants that match the name you entered. Click one of the plants in the table to learn a lot of detail about that plant, in particular, where it's been observed in California.
Try it out!
Find Out What Plants Grow in a Place
You can also enter a place and get an illustrated list of
the plants that grow there. We call that
What Grows Here?
You define "here" by zip code, place name, or any of a number of other ways. You refine "here" by zooming in and out of a map. Then click "Search for Plants" to get an illustrated list of plants known to grow "here."

The Calflora Community
We (the Calflora team -- see above) rely on
a community of interested and engaged users.
If you are interested in wild plants in California,
you are cordially invited to join this community.
So, for instance, if you are aware of a plant growing wild
in some park or other location where it is not yet
shown on Calflora, we urge you to become a contributor and
to add an observation of that plant where you know it grows.
On the other hand, if you notice information on Calflora
that seems wrong or incomplete, please
let us know.
If it is an observation record that does not look right
and you are a contributor, you can write a comment on the record.
We do pay attention to comments and answer emails!
In this sense, what you see on Calflora is in part the product of
the vigilance of engaged users.
