Ferns and Lycophytes Basic Biology ~ Ferns and lycophytes are two groups of vascular plants without wood seeds or flowers They are both ancient groups of plants that once dominated the forests in many parts of the world They have since been outcompeted by angiosperms and gymnosperms as the dominant plants but are still an important component of the plant community in many forests

Biology and Evolution of Ferns and Lycophytes Botanical ~ The chapter Evolution of the nuclear genome of ferns and lycophytes points out a crucial gap in current fern research The long delay in the acquisition of nuclear markers in ferns compared with angiosperms is regrettable especially as nuclear markers may shed new light onto introgression and hybridization processes
