From museum to laptop: Visual leaf library a new tool for identifying plants (PennState)

PennState: From museum to laptop: Visual leaf library a new tool for identifying plants. “Fossil plants reveal the evolution of green life on Earth, but the most abundant samples that are found — fossil leaves — are also the most challenging to identify. A large, open-access visual leaf library developed by a Penn State-led team provides a new resource to help scientists recognize and classify these leaves.”

Nature.com: Massive database of 182,000 leaves is helping predict plants’ family trees. “The story of a plant is etched in its leaves. A tree growing in a cold environment with plenty of water is more likely to have large leaves with many serrated teeth around the edges. But if the same species lives in a warm, dry region, its leaves are likely to be smaller and smoother. Now, an atlas that traces the shapes of 182,000 leaves from 141 plant families and 75 locations around the world shows promise for refining scientists’ ability to read that story. “
