New mobile app released

On May 1, 2023, we released our mobile app called FloraQuest: Northern Tier, a new plant identification and discovery app covering over 5,800 vascular plants in the northern part of our Flora area. With graphic keys, dichotomous keys, habitat descriptions, range maps, 20,000 diagnostic photos, and over 170 great places to botanize, FloraQuest: Northern Tier is the perfect companion for your botanical explorations. It doesn't need an internet connection to run, so you can take it with you anywhere.

Check out our talk on FloraQuest, the FSUS Web App, and all things Flora of the Southeast.
