Misc. Stone, in 1910, says "These curious little plants, practically devoid of leaves, are more common than generally supposed, but frequently escape attention, buried as they are among the taller vegetation. They are named in honor of Prof. Benjamin Smith Barton (1766-1815), professor of botany in the University of Pennsylvania and author of a general work on botany and the interesting "Fragments of Natural History" in which the blooming of plants, arrival of birds, etc., are arranged in chronological tables."
