description

Achillea oxyloba subsp. oxyloba

The Dolomite yarrow is a grass-forming, perennial plant that grows to a height of 8 to 20 (30) cm. It has a branched, widely creeping rhizome. The arching, ascending to upright stem is usually one-headed, its lower part is leafy, the upper part is haired in different densities. The sparsely hairy, dark green leaves have an elongated outline and are deeply pinnately fissured, their narrow sections are three to five-lobed or whole. The leaves sit on the stem, only the lower ones are short stalked.

The heads are approximately 28 mm in diameter. The bracts of equal size are oblong and blunt and have a wide, black skin edge. There are 13 to 18 broad, linear, white ray florets. The tubular flowers are yellowish-white.

Flowering time is from June to September.

The chromosome number is 2n = 18, also for the subspecies Achillea oxyloba subsp. shurii .

Occurrence

The dolomite yarrow is endemic to the eastern Southern Alps and the Carpathian Mountains. The distribution area in the Alps extends from Val Camonica to the Carnic Alps (Switzerland, Italy, Austria). The species prefers to thrive on rocky lawns, rock debris over limestone and dolomite at altitudes of 1600 to 2800 m.

For the region around Fusch im Pinzgau , the names Birgssonnawendblüh and white Sonnawendblüh are also used for the Dolomite yarrow .

Systematics

One can distinguish between two subspecies:

Achillea oxyloba (DC.) Sch. Gdp. subsp. oxyloba : It occurs in Austria and Italy.
Achillea oxyloba subsp. schurii (Sch. Bip.) Heimerl (Syn .: Achillea schurii Sch. Bip. ): It occurs in the Carpathian Mountains in Romania and in the Ukraine.
