Draft:Cirsium × juratzkae

Cirsium × juratzkae (Cirsium greimleri × heterophyllum) is a hybrid between C. greimleri and C. heterophyllum.

It is known from 58 herbarium specimens as of 2020.

It is found in the Rottenmann and Wölz Tauern, Schladming Tauern, Seckau Tauern, and Lavanttal Alps.

It was named after Jakob Juratzka. It was described it as one of the most "stately and beautiful" hybrids by Heinrich Wilhelm Reichardt, who identified it in 1861 near Bretstein and near Breitenau am Hochlantsch, both at 1400 m.

Although the growth is more similar to C. heterophyllum and the flowers more similar to C. greimleri, the leaves of the hybrids are intermediate between both parents, with significant variation.
