List of plant orders

This article lists the living orders of the Viridiplantae, based primarily on the work of Ruggiero et al. 2015. Living order of Lycophytes and ferns are taken from Christenhusz et al. 2011b and Pteridophyte Phylogeny Group. Living orders of Gymnosperms are added from Christenhusz et al. 2011a while extinct orders are from Anderson, Anderson & Cleal 2007.
