In the above cited article, there was an error in the Identification key for Erigeron acris s.l. occurring in Poland (page 172). It previously read:
(1) Stems and leaves densely villous, involucral bracts abaxially densely villous and sparsely
short-stipitate glandular … 2
(2) Stems and leaves glabrous or sparsely villous at the base, involucral bracts abaxially densely short-stipitate glandular, glabrous or sparsely villous … 3
(3) Outer ray flowers with short, usually white or lilac ligules, exceeding the involucre by up to 2 mm … 4
(4) Outer ray flowers with long, usually pink ligules, exceeding the involucre by up to 4 mm … Erigeron acris subsp. podolicus
(5) Basal leaves with acute apex; cauline leaves narrowly lanceolate to linear; peduncles spar-
sely short-stipitate glandular or glabrous; capitula in racemiform synflorescence … Erigeron
acris subsp. angulosus
(6) Basal leaves with obtuse apex; cauline leaves lanceolate; peduncles densely to sparsely villous and short-stipitate glandular; capitula in paniculiform synflorescence … Erigeron acris
subsp. droebachiensis
(7) Cauline leaves 4–16, flat, usually erect; inter-nodes 1.0–8.0 cm; capitula in paniculiform
synflorescence … Erigeron acris subsp. acris
(8) Cauline leaves 12–36, broadly undulate, recurved; internodes 0.2–3.8 cm; capitula in racemiform or paniculiform synflorescence … Erigeron acris subsp. serotinus
It has now been corrected to:
