ABSTRACT. A new name, Geranium tanii Aedo & Muñoz
Garmendia, is proposed for the illegitimate later homonym Geranium
trifoliatum Z. M. Tan.
While preparing an index of specific names in Geranium,
we encountered a problem concerning nomenclature of the Chinese
G. trifoliatum recently described by Tan (1990). Andrews
(1805--1806) used this epithet for a South African Geranium
now recognized as Pelargonium trifoliatum (Andrews) Sweet
(Sweet, 1826). According to Article 53.1 of the Tokyo Code, Tan's
name is illegitimate due to later homonymy. Thus, the following
name change is necessary.
Geranium tanii Aedo & Muñoz Garmendia, nom.
nov. Replaced name: Geranium trifoliatum Z. M. Tan, in
Bull. Bot. Res., Harbin 14(3): 231. 1990, nom. illeg. Not Andrews
(1805).
