Cultivars established in the three nothogenera ×Graptophytum Gossot, ×Graptoveria Gossot, and ×Pachyveria Haage & Schmidt (Crassulaceae) have entered specialist and general horticulture, and are increasingly and widely cultivated, especially in mild-climate parts of the world. However, uncertainty has existed regarding the place of valid publication and authorship of two of these nothogenus names ×Graptophytum Gossot and ×Graptoveria Gossot. We show that both names were validly published in a littleknown book, Liste des Plantes Grasses sauf Cactées du Jardin Botanique des Cèdres, which was published by J. Marnier-Lapostolle in 1949. Both names should be attributed to [Pierre] Gossot. ×Pachyveria was validly published by Haage & Schmidt in 1926. Notes are included on the author attribution ‘Haage & Schmidt’.
