Habitat:Larch and pine forests, birch groves, forest fringes, shrubberies, forest meadows and clearings (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 genus Vicia: herb
perennial (i)Living for several to many years, as opposed to annual and biennial
Parasite status: (i)Is the plant a half- or full parasite?no parasite/saprophyte (i)Plant fully autonomous, leaves with chlorophyll
example: Most plants, Ranunculus

Water or terrestrial plant: (i)Where do the plants grow?terrestrial (i)Plant grows on dry land

Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)
Leaf arrangement: (i)Arrangement of leaves at the stem.alternate (i)One leaf per node; distiche: arranged in two vertical rows, equitant
example: Phragmites
inherited by family Fabaceae: alternate
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.imparipinnate / ottpinnate (i)A pinnate leaf with an central unpaired terminal leaflet
paripinnate / evenpinnate (i)A pinnate leaf with all leaflets in pairs inherited by genus Vicia: paripinnate / evenpinnate

pinnate (i)With leaflets on both sides of an axis, at least 2 pairs or more
example: Onobrychis
inherited by genus Vicia: pinnate
Leaf margin: (i)Structure of leaf margin (or that of a leaflet in case of compound leaves). Attention: Here we ask for the leaf margin, defined as all those dissections that separate the leaf for less than one third of its length or width, whatever is smaller. To be worked out: how to handle margin of pinnate leaves?serrate / dentate / crenulate (i)Margin saw-like or rounded teethed
example: Betula, Lophanthus (crenulate)

finely serrate / dentate (i)Fine teeth, more than 20 per leaf length; usually only one lateral vein per tooth

Perianth arrangement: (i)Attention: in some plants, flowers may be dimorphic in different ways (dioecious or gynodioecious). If flowers vary, record the characters of the most showy flowers.double, different (i)Two types of perianth leaves, differently coloured (sepals: outer periant leaves, usually greenish, and petals: inner perianth leaves, usually coloured)

inherited by family Fabaceae: double, different
Diameter of flower: (i)Diameter of flower or flower head. from 10 mm to 20 mm (i)
example: Potentilla

Flower symmetry: (i)Symmetry of the perianth leaves. Attention: to assess this character, look on sepals, petals and stamens, but neglect carpels and ovary.zygomorphic (i)One axis of symmetry, monosymmetrical flowers
example: Pedicularis, Nepeta, Viola
inherited by family Fabaceae: zygomorphic
Flower form: (i)common forms of flowers ? Veronicapapilionaceous (i)Butterfly-like flower is structured: standard, 2 wings and keel
example: Most Fabaceae (Astragalus), Polygala
inherited by family Fabaceae: papilionaceous
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. Be aware of the bracts (involucral leaves) of Asteraceae flowerheads, do not qualify these as sepals! Be also aware in Rosaceae is often an epicalyx developed, in this case count all parts.5 (i)
example: Polemonium
inherited by family Fabaceae: 5
Sepal fusion: (i)To which degree are the sepal leaves connected? Attention, this character applies only for flowers separated in sepals and petals, thus excluding most monocots. Be aware of the bracts (involucral leaves) of Asteraceae flowerheads, do not qualify these as sepals!fused (i)Leaves united, only tips are free

example: Silene
inherited by family Fabaceae: 10
Stamen fusion: (i)To which degree are the stamens fused? Attention: Whereas the pollen sacs itself are often free., their stalks (filaments) may be fused. Here, we count them as fused if they are together over at least one thirth of their length.fused with each other (i)All or most stamens fused with each other to a tube-like structure
