Eryngium thorifolium is a species of flowering plant in the family Apiaceae, endemic to Turkey.
Description and habitat Eryngium thorifolium is an Eryngo with single tall stem (to 1.5 m), based with round, shield-like, saw-toothed greyish leaves and smaller ones up the stem, flowering with a few branches of yellowy-green flower heads. Under the heads are 6–8 spiny bract-leaves, within the heads the individual flower bracteoles are three-part.
It naturally grows on rocky serpentine soil, and apart from Eryngium pseudothorifolium, lacks close allies.
It may be confused with Eryngium pseudothorifolium, whose leaves are more wedge-topped and less indented at the base, with only 1–3 flower heads, and which grows on marly soil, and also with species of Pimpinella, such as Pimpinella flabellifolia.
Distribution It is native to the far southwest of Turkey.
