Initially published as Botanical Register from 1815 to 1828 (vol. 1 to 14), it becames Edwards's Botanical register in 1829 (vol. 15). Publication stopped in 1847 (vol. 33). The very nice plates that illustrate cacti and succulents of both series are given here as a single interpreted file.
This series was created by Sydenham Edwards after a dispute with the editorial board of the (Curtis's) Botanical Magazine. This explains why Edwards's register looks like a clone of Curtis's Magazine.
