On this encore episode, Missouri Botanical Garden scientist, Charlotte Taylor, names 500 new species of plants. That makes her the most prolific living female botanist — an accomplishment only revealed last year by researchers from Royal Botanic Gardens, Kew and the University of Cambridge. The researchers found Taylor is the third most prolific female botanist in the field — ever. Taylor discusses her contributions to the field of botany and takes us inside the world of a world-class taxonomist.
