Dubious records, and species to be excluded.
In the older works on Icelandic botany there are included several species of
Hieracium which it is impossible to identify with any of the species dealt with above.
Some of the records are evidently due to wrong determination. Below is given a list
of these species:
Hieracium aurantiacum
Gliemann, 1824, p. 146 (after Morch).—Babington, 1871, p. 315.
Hieracium Auricula.
K. & M., 1770, p. 209.—Gliemann, 1824, p. 146.—Babington, 1871, p. 315.
Hieracium basifolium var. alþestre Lindebg. exsicc.
Strömfelt, 1884, p. 106.—Bennctt, 1886, p. 69.
