Norrlin J. P. (1923). Adnotationes de Pilosellis Fennicis. I Notices on Pilosellae (Hieracia sp.) (hawkweed) in Finland. Silva Fennica vol. 23 no. 8 article id 7107. https://doi.org/10.14214/aff.7107

Abstract

The article begins on the page 105/122 of the PDF file.

The article deals with the morphology of Hieracia sp. and their research, especially with Pilosella officinarum, also Hieracium pilosella. The article gives an overview of the most common, wide spread or otherwise remarkable forms of the genus of the Pilosella and reports, starting from the smallest areas, about the formula, distribution, abundance and occurrence of them.

The great amount of forms, their high variability and the tendency to hybridize make the definition of the varieties difficult.  However, the number of varieties in Finland is estimated to be between 150 and 200. The phenotype of the plant is also to some extent dependent on the site. The numerous forms that belong to the group of Piloselloideae can be divided in to groups: main species and intermediate forms.
