Abstract
APPARENTLY the only plants reported to have successive rings of true cork in the wood are certain species of Sedum1,2. There are, however, the closely related cases of Gentiana cruciata, Aconitum Lycoctonum, Salvia spp.3, Delphinium spp.4,5, and Mertensia spp.8, in which cork develops to some extent in the xylem, but is rarely found there in the form of concentric layers. In these plants, as also in Sedum spp., internal cork is said to arise in connexion with the splitting of the rhizome or root into strands and the segregation of vascular bundles directly connected with effete leaves and annual shoots. There are also on record7 examples of localised and anomalous cork layers round groups of vessels in the wood of various species. Finally, there is the case, recently described by Lemesle8, of concentric suberised layers in the wood of Hymenocrater spp.; but here, no cork cambium is formed and the suberised layer is properly described by Lemesle as a pseudoperiderm.
