Cirsium × reichardtii (Cirsium greimleri × palustre) is a hybrid between C. greimleri and C. palustre.[1][2][3]

It is known from 38 herbarium specimens as of 2020.[4]

Distribution

[edit]

It is found in the Rottenmann and Wölz Tauern, Schladming Tauern, Seckau Tauern, Lavanttal Alps, and Karawanks.[4]: 84 

Description

[edit]

The flowers tend to appear close to C. greimleri,[1] but there is variation between individuals closer to C. greimleri and individuals closer to C. palustre.[2]

The description of Juratzka:[1]

Rhizome unnotable. Stem protruding only in the upper part; lower part denser above more distantly leafy slightly arachnoid with articulated hairs (C. palustre), sparsely branched above, with sub-elongated arachnoid branches (common peduncles). Oblong leaves (lower to 7 lines long and 4 lines wide) rounded-eared, lower to the length of a line, running sinuate-pinnatisect spinose-ciliate, with the lower fins equaling part of the blade in length, with 2-3 subsuperior lobes, oblong-triangular anterior lobes, sparsely hairy above (as in C. palustre), densely cano-arachnoid below; ribs with scattered soft articulated hairs. Capitula on peduncles in pairs and in threes, pedicels 1-3 lines long white-tomentose indentations with filioloque suffulta. Involucres brownish-purple scales appressed to a viscous carina, the margin a little arachnoid obsolete spiny, violet-purple flowers (male) 7 1/2 lines (limb c. throat 4 1/2 lines, tube 3 lines) long.
