Symphyotrichum pilosum (Willd.) G.L.Nesom var. pringlei (A.Gray) G.L.Nesom, Phytologia View in CoL , 77 (1994, 3): 289. 1995.
( Asteraceae )
Naturalized neophyte new to the flora of Piemonte ( Conti et al., 2005; Celesti-Grapow et al., 2009a).
ITALY. Piemonte. Prov. Vercelli: Ghislarengo , ca. 1.5 km SW of the village, abandoned gravel pit, common, 06.09.2014, F. Verloove 10985 ( BR, MSNM) .
Symphyotrichum pilosum View in CoL is native in eastern North America ( Brouillet et al., 2006) but widely cultivated as an ornamental in Europe. It is a poorly known species that has been confused with S. ericoides View in CoL ( L.) G. L.Nesom, S. lateriflorum View in CoL ( L.) Á.Löve & D.Löve and even S. lanceolatum (Willd.) G.L.Nesom. Italian View in CoL claims of the first two species are mostly erroneous and referable to S. pilosum ( Banfi & Galasso, 2010) View in CoL . The latter is fairly characteristic in having pedicels with numerous linear to subulate bracts and phyllaries with acute, spinulose apices. Stems and leaves may be either pilose to hirsute ( var. pilosum ) or glabrous ( var. pringlei View in CoL ).
In Italy Symphyotrichum pilosum View in CoL was only known with certainty from Lombardia ( Banfi & Galasso, 2010) although it may have been overlooked elsewhere. In Ghislarengo it has invaded rough ground in an abandoned quarry. It looks perfectly established there.
