Cirsium × stiriacum (Cirsium greimleri × rivulare) is a hybrid between C. greimleri and C. rivulare.[1][2]
It is a rare hybrid, known from only 4 herbarium specimens as of 2020.[3]
Distribution
[edit]It is found only in the Lavanttal Alps and Karawanks.[3]: 85
Description
[edit]_-_Werner_(cropped).jpg)
The type specimen was more similar to C. greimleri than to C. rivulare, but bore pinnately divided leaves, too thinly webbed on the underside for pure C. greimleri.[2]
The description of Reichenbach:[4]
Stems furrowed, slightly hairy; branched at the top, fairly hairless there; head-bearing branches evenly arranged; heads sometimes almost sessile; leaves encircling the stem, sinuously pinnate, sections triangular, here and there coarsely toothed or serrated; surface of the leaves sparse, veins somewhat more glandular-hairy; heads elongated, supporting linear, narrow, intact leaves; bracts lanceolate, dagger-pointed, protruding from the tip to the middle, sticky keeled, ciliate at the edge, protruding at the tip; flower border equal in length to the tube; truncated at the tip; somewhat lobed. Heads large. Flowers dark purple.

Taxonomy
[edit]Identified on 29 June 1903 by Karl Fritsch in the Lassnitz valley.[2] Although earlier authors believed it had been found by Tommasini on Snežnik,[4][2] that record was doubted by subsequent authors.[5]
