Draft:Cirsium × stroblii

Cirsium × stroblii (Cirsium greimleri × spinosissimum) is a hybrid between C. greimleri and C. spinosissimum.

3 herbarium specimens as of 2020.

It is found only in the Rottenmann and Wölz Tauern, although the range overlap extends to nearby ranges.

Identified by August von Hayek in the summer of 1906 from a specimen collected on the slopes of a ravine that feeds the Großer Bösenstein lake by Gabriel Strobl in 1867.

There are few specimens, but it is close in appearance to C. heterophyllum × spinosissimum, differring in having broader leaves with short lobes, without tomentose undersides.
