Something more easily done with an online publication than a printed one. The problem is the NCL was based mainly on morphology which DNA Sequencing has knocked a considerable number of holes in, so really to make a proper job both volumes would really need updating and the pictures re-ordering to reflect the revised classification. Therefore presumably there will be some form of update. David Hunt is still posting updates in his Cactaceae Consensus Initiatives, which are now being distributed by email to subscribers rather than in printed form.
