| Abstract Detail
Themes of land plant evolution, a celebration of the contributions of Leo J. Hickey Green, Walton [1]. The parichnos problem, a foray (after Hickey) into Paleozoic paleobotany. Most of the late Leo Hickey's paleobotanical investigations concerned flowering plants, but his instinct for approaching the plant or ecosystem as a real biological entity pertained even in the Paleozoic. For instance, parichnos is a term describing an anatomical feature in Lepidodendron bark impression fossils that was originally devoid of biological significance. In the last few years, I have been trying to reexamine a debate over the function of the parichnos system that last appeared in the paleobotanical literature in the beginning of the 20th century. Here, trying to emulate Hickey's thoroughness in exploring the historical background of botanical terminology, I trace the use of the term parichnos from its beginning, consider its possible biological interpretations, and discuss its potential significance for the interpretation (or reinterpretation) of Paleozoic coal-swamp communities.
