A note on the Saint Louis Code 2000 is contributed by Roy Mottram, and its effect on names in this index is discussed. The alphabetic index of Opuntia names is continued from Bradleya 18: 113–140. 2000. Includes eight new typifications (1 LT, 5 NT, 2 ET), and six new cultivar standards. Two paintings by Duncanson, lodged in the Kew herbarium, are reproduced here for the first time.
