Summary The structure of the xylem body of nine woody species of Sedum belonging to two different groups was studied with respect to the character states of the characters correlated with the hybridization patterns of the species. No significant differences in the structure of the wood were found between the specialized and less advanced species. Like the wood of Aeonium, Kalanchoe , and Cotyledon , the features of the wood of Sedum indicate secondary woodiness or paedomorphosis. These results support the idea that the Crassulaceae descended from an herbaceous ancestor and that woodiness evolved independently in several groups.
