The long-running hawkweed ( Hieracium × longistolonosum ) is an extinct hybrid that arose from the parent species Hieracium bauhini and Hieracium peleterianum within the genus of the hawkweed ( Hieracium ). It was a micro- endemic occurring in Bavaria .
features
The forked stems, covered with protruding, long hairs, reached a height of 20 centimeters. They were either leafless or had a small leaf on the lower half. The plump runners were very long. The flower heads were quite large and glandular below. The lanceolate rosette leaves were long and stiff-bristled, gray-tomentose underneath and, like the leaf margins, soft-haired. The bracts either had many glands and few hairs or few glands and many hairs. The flowering time was in June.
Occurrence and status
The cross-country hawkweed was only known from the Tegernheim mountains and the Scheibelberg near the village of Donaustauf near Regensburg . According to a final record in 1937, this plant is considered to be most likely extinct.
