This is a revised and completely restructured 13th edition of Engler's Syllabus, originally written in German, and is being published in 5 volumes in English for the first time.
Volume 3 (the first published of 5 volumes scheduled) provides a thorough treatment of the morphological and molecular diversity of lower plants including Marchantiophyta, Bryophyta, Anthoceratophyta, Tracheophyta, Rhyniophytina, Lycophytina, Trimerophytina, Moniliformopses and Radiotopses. The advance DNA sequencing and advances in phylogenetic analysis has raised new interest in the relationships of liverworts, mosses, hornworts, ferns and fern allies as extant representatives of early land plant evolution.
