Abstract
In a taxonomic treatment of Kalanchoe Adanson (1763: 248) (Crassulaceae subfam. Kalanchooideae) in Madagascar, 13 nomenclatural novelties at the ranks of species, variety, and forma were validly published by Boiteau & Allorge-Boiteau (1995). In three cases that have gone unrecorded this was done inadvertently, but nonetheless validly. In the other 10 cases, Boiteau & Allorge-Boiteau (1995) variously and explicitly ascribed the new names and new combinations published in that work to either: (1) P. Boiteau, or to (2) L. Allorge-Boiteau. Only in three cases, that of the inadvertently validly published replacement name K. marnieriana H.Jacobsen ex Boiteau & Allorge-Boiteau (1995: 102) and the inadvertently validly published new combinations K. synsepala Baker (1882: 110) var. trichantha (Baker 1883: 140) Boiteau & Allorge-Boiteau (1995: 179) and K. integrifolia Baker (1887: 471) var. bitteri (Raymond-Hamet & Perrier de la Bâthie 1914: 120) Boiteau & Allorge-Boiteau (1995: 183), were Boiteau and Allorge-Boiteau co-authors of the names.
