IAN symbol libraries currently contain 3042 custom made vector symbols for science communication, including eight flora themed albums. Each free botanical icon set can be downloaded as an individual file or on palettes as shown below. You can use them cost and royalty free for any use, with attribution to the University of Maryland Center for Environmental Science. Such a diverse range of organisms are covered here in quite some detail, making them much more unusual, extensive and interesting than your average stockphoto plant or botanical icon image. Download and load into Photoshop and Illustrator or just keep in your images folder to use in whatever way you want.
