Harvey (1860) unfortunately overlooked the fact that the name R. meyeri had already been proposed by R.T. Lowe (1857) as a replacement name for the East-Central Asian R. grandifolius E.Mey. (1830) under the misapprehension that the latter was synchronous with his R. grandifolius Lowe (1831) from Madeira. In fact it is R. grandifolius Lowe that is the illegtimate later homonym and thus requires a new name, and R. meyeri Lowe becomes an illegitimate superfluous name for R. grandifolius E.Mey. This renders R. meyeri Harv. an illegitimate later homonym requiring a new name, for which we propose R. dregei in honour of the original collector of the species.
