Raunkiær’s life-form of the species. Raunkiær’s system is based on the perennating organs (seeds or buds), and in the latter case on the position of the buds relative to the soil or water surface during the unfavourable season.

Ph - Phanerophytes: woody plants with resting buds high above the soil surface

MM - Mega-mesophanerophytes: trees
M - Microphanerophytes: shrubs
N - Nanophanerophytes: subshrubs

Ch - Chamaephytes: perennial plants with resting buds close to the soil surface (dwarf shrubs, cushion plants).

H - Hemicryptophytes: perennial plants with resting buds on the soil surface or right below the surface

G - Geophytes: perennial plants with resting buds in the soil, well below the surface

HH - Hydato-helophytes: aquatic plants with resting buds in the water or at the bottom of the water body

TH - Hemitherophytes: biennial plants that overwinter in the first year and die in the second year after fruit ripening

Th - Therophytes: annual plants that survive unfavourable seasons in the form of seeds

 E - Epiphytes: plants living on other plants, mostly on trees
