Check out the violet key at the Delaware Wildflowers web site. Great photos too.

The California Flora project has a neat app to report observations of any of their species in California. According to their website: This application makes it easy for you to report the species name, date, and location of over 10,000 California native and non-native plant taxa. You can also add a photograph to a report, and share it with others later to confirm identification. Your reports are transmitted wirelessly to the Calflora database, where you can edit them and see them on a map. To read more about it CLICK HERE. The Bay Area Early Detection Network uses it to map invasive plants. Below is a 9 minute video of how that works. The app demonstration starts at minute 2:15. Would it be useful to have something like this for the New York Atlas?
Here is a good video from the University of Wyoming about how to collect plants for botanical specimens.
I recently came across a website called identifythatplant.com by Angelyn Whitmeyer from North Carolina that contains resources and tips for identifying plants. One of the videos is below:

This is a good website for beginners and contains useful information on plant identification. Check it out and let others know what you think in the comments section. – Steve Young
The NY Natural Heritage Program and environmental firm Tetra Tech are teaming up this summer to assess the condition of various wetlands across New York for the EPA. The project began with wetlands in the Adirondacks, continues on to Western New York, and finishes on Long Island. Below are some photos from the work in the Adirondacks. – Steve Young
In a recent post the new tree identification Apple app Leafsnap was featured. I collected 5 tree leaves today to see how well it worked. Here are the results:
1. American elm – It had it listed as its 4th guess.
2. Witch hazel – It was not in the database. I guess it considers it a shrub.
3. Gray birch – Right on its first guess.
4. Cottonwood – Right on its first guess.
5. White ash – It was listed as its 10th guess.
There are quite a few exotic trees in the database which are very similar to our native leaves, especially the compound leaves. It certainly was not perfect but we will test more leaves soon to see if it does better. – Steve Young
Many years in development, the leaf identification app Leafsnap is finally available for the iPhone and iPod touch with camera and wifi connection. It will be interesting to see how it will be integrated into dendrology and other flora classes. See the YouTube video below to see how it works. Are the graminoids next?
If you want to enter GPS coordinates in web-based maps it can be a hassle to convert the coordinate systems depending on how you record them. There is a great website that does it for you and with one click will go to the web map you want. It is called leware.net and can be found at http://leware.net/geo/utmgoogle.htm. For a UTM set of coordinates, for example, just fill in the yellow boxes with zone 18T and hit the display button. It will take you directly to your location on the map, even in Bing Birds-eye view. This is a very simple and handy tool that I use all the time now to find locations that I record on my GPS. – Steve Young
