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.

The article describes the development of collecting botanical knowledge of Finnish vegetation, and the problems that have occurred with the aspirations, to examine the Finnish vegetation and to collect the examples of the species. It also gives recommendations how the future studies on vegetation should be organized.

The data has been collected during summer 1867. It examines the moos and lichen species in for regions of Lapland: spruce region, pine region, birch region and fjeld region. The division of the regions is related to the climatic and biological conditions of areas, the first mentioned being the most southern and still suitable e.g. for many grasses. Respective regions have been presented with their general characters and list of species. Finally the findings of different regions are compared.

The article is a travel report of the author’s travel from Helsinki to north of Finland. Alongside the description of the travel arrangements, it contains observations about the vegetation of the destinations they visited. The observations are divided into section of “spruce region”, “pine region” and “fjeld region”.

The first part of the text deals with a general presentation of the geographical, biological and cultural conditions of the studied areas. The second part presents the characteristics of vegetation classified according the forest types, with lists of species. Forested areas, open lands and swampy areas are dealt with separately. The Saoneshje peninsula is presented separately.
The third part of the text discusses the similarities of the natural conditions between studied area and respective part of Finland. The vegetation and amount of species is clearly more diverse in studied area than in parts of middle-Finland. The study shows that in respect to vegetation Onega-Karelia cannot be seen as a part of the same region than Finland.

Data for this paper have been collected during years between 1859 and 1862 in the communes of Asikkala, Hollola, Padasjoki, Lammi and Koski.
The first part of the text deals with a general presentation of the geographical, biological and cultural conditions of the studied areas. The second part presents the vegetation according their habitats; they are classified by the degree of moisture. The last is further classified as forested areas or open lands. The examination concentrates on phanerogams (seed plants).
The characteristics of vegetation of forests, open lands and paludified places (swampy or swamp forming places) are presented with the most influential characters and lists of species.
The text is the opening presentation by the author at his public defence of his doctoral thesis on plant geography of Finland. The text discusses the principles that apply on plant geographical classification of earth with respect to characteristics of vegetation and gives an oversight on the plant geographical work conducted in Scandinavia.
