368. PuGSLET, H. W. On Hieracium aurantiacum L. Jour. Botany 59: 60-69. 1921. — 

 This species as it occurs in Britain is divided by the author into 2 species, one with subter- 

 ranean stolons, broad leaves, and orange red or brick red heads, and another with superficial 

 stolons, narrow leaves, and brownish-orange heads. The former is considered to be the typical 

 H. aurantiacum of Linnaeus, while the latter is described as new under the name H. brunneo- 

 croceum. — K. M. Wiegand
