Diversity of ferns and lycophytes studies
WebBiology and Evolution of Ferns and Lycophytes - Tom A. Ranker 2008-06-19 With their team of contemporary scholars, the editors present a thorough coverage of fundamental topics necessary for obtaining an up-to-date understanding of the biology of ferns and lycophytes. The book is WebThe vascular plants are divided into the seedlesslycophyta (club mosses) and the seedless pteridophyta which includes whisk ferns, horsetails and the more familiar true ferns. The ferns have rigid stems, true roots as well as vascular tissues. These two groups still require moisture for fertilization but their haploid spores travel through the air.
