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." (642)
