First described in 1995 by Texas botanist Karen Clary, Y linearifolia has had a troubling two decades. Since this initial description, the plant, which grows only in small zones of Mexico's Chihuahuan Desert, has been sought-after by illegal harvesters. "There's a chance they could be used to facilitate poaching, so there's a need for the community to define guidelines around this," Pace says of the Endless Forms project. "When you're dealing with really rare plants, that increases their wow factor. For someone to say, I'm the only person in the world who has this extremely rare plant in my collection, that's a huge status symbol."
