Retkeilykasvio (Field Flora of Finland)

Hämet-Ahti, L., Suominen, J., Ulvinen, T. & Uotila, P. (eds.) 1998: Retkeilykasvio (Field Flora of Finland), Ed. 4. 656 pp. Finnish Museum of Natural History, Botanical Museum. Helsinki.

Retkeilykasvio, Field Flora of Finland, includes all vascular plant species and subspecies, and most important varieties and hybrids, native or clearly established aliens in Finland, as well as casual immigrants and cultivation escapes which have been found at least several times. However, only selected species are treated in the apomictic groups of Hieracium, Pilosella, Ranunculus and Taraxacum.

Scientific names are followed by the Finnish name and the Swedish name. The morphological description, especially as to measurements, is mainly based on Finnish plants, and its sequence is as follows: height, stem, leaves, inflorescence, flowers, fruits. Illustrations have been made of Finnish specimens. Chromosome numbers are included, those counted on Finnish material with bold characters. Flowering months are given with Roman numerals. These, as well as ecological data, are based on the Finnish situation. Some taxonomical notes and possible protection by law are given. At the end of the description, edible plants have been marked with an asterisk (*), poisonous plants with a cross (†) and very poisonous plants with two crosses (††).

Map symbols

The distribution in Finland according to biogeographical provinces is given with maps. The maps are based on data from herbarium specimens, reliable literature, the "Atlas of the Finnish Flora", and field notes. The 11 map symbols used are as follows:
