Abstract
In 1994 Tzvelev described ×Asterigeron ucrainicus Tzvelev, which he interpreted as a hybrid of Aster amellus L. and Erigeron acris L., and thus established a nothogenus ×Asterigeron Tzvelev (Aster L. × Erigeron L.). However, the name ×Asterigeron Tzvelev is a later homonym of Asterigeron Rydb.; because of that a new replacement name, ×Asterron Olshanskyi, is proposed for this nothogenus. Also, the new nomenclatural combination ×Asterron ucrainicus (Tzvelev) Olshanskyi (≡ ×Asterigeron ucrainicus Tzvelev) is validated.
