Distribution

CH, DE, FR-FRA.

Habitat

In gorges, rough valleys and screes, 400–2300 m a.s.l.; also broad-leaved forest at 330 m a.s.l.

Remarks

Pedroli-Christen (1993) provisionally included H. helveticum, H. jurassicum and H. cornigerum in her concept of H. alemannicum and noted that this complex may constitute one polytypic species. We adopt this view but follow Spelda (2008) in using the older name helveticum .
