Habitat:Pebbles at river banks, larch forests, birch kolki, forest fringes, clearings, fire sites, forest meadows, meadow slopes (Grubov 2001).
Habit (i)general appearance of a plant
Growth form: (i)Herb, shrub, tree or climber.herb (i)Herbaceous, erect plant, up to 2m high, mostly with a leafy shoot; if perennial, shoots die to the ground each season, shoots are not woody
example: Artemisia pectinata
inherited by family Onagraceae: herb
Size of plant: (i)Attention: use flowering or fruiting specimens to assess plant height (many biennial plants possess only a basal rosette in the first year). from 250 mm to 600 mm inherited by genus Chamaenerion:
from 600 mm to 1000 mm inherited by genus Chamaenerion:
Parasite status: (i)Is the plant a half- or full parasite?no parasite/saprophyte (i)Plant fully autonomous, leaves with chlorophyll

Simple or divided leaves: (i)Are the leaves simple or completely divided in several parts? Blade of the leaf entire or (more or less) deeply dissected. Attention: There are various appearances of the leaf margin (from entire to toothed and lobed). Here, we ignore this and ask only for dissections that separate the leaf for more than one third of its length or width, whatever is smaller. Sometimes, it is difficult to tell apart compound leaves from a shoot system with simple leaves: look for stipulae and/or axillary buds at the ground of the leaves: if only some possess these structures, the others are most likely leaflets of a compound leaf.simple (i)Non-divided leaf, but margin may be incised nearly to the ground inherited by family Onagraceae: simple
Shape of blade: (i)Easy for simple leaves. In compound leaves use the general shape of leaflet. Always check the ground for largest leaves of a plant.

inherited by family Onagraceae: radiary, regular (actinomorphic)
zygomorphic (i)One axis of symmetry, monosymmetrical flowers

Sepal number: (i)Number of sepal leaves (outer perianth leaves, calyx leaves, mostly greenish). Attention, this character applies only for flowers separated in sepals and petals, thus excluding most monocots.
