| Habitat: | Waterside alkaline meadows, river banks, pebbles, rarely solonchaks, sometimes as weed (Grubov 2001). |
| Habit (i)general appearance of a plant | |
| Growth form: (i)Herb, shrub, tree or climber. | biennial (i)Taking two years from seedling stage to maturity, seed-set and death; often only with a rosette of leaves in the first year
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 Melilotus: herb
|
| 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 inherited by family Fabaceae: no parasite/saprophyte
|
| 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. | trifoliate (i)Three-parted leaf (often called ternate)
example: Trifolium, Thermopsis  inherited by genus Melilotus: trifoliate
compound (i)Composed of several similar parts inherited by genus Melilotus: compound
|
| 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. To be worked out: how to handle pinnate leaves? | lanceolate (i)Lance-shaped; much longer than wide, with the widest point in the middle or below 
|
| 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)  inherited by genus Melilotus: serrate / dentate / crenulate
finely serrate / dentate (i)Fine teeth, more than 20 per leaf length; usually only one lateral vein per tooth
example: Pedicularis  inherited by genus Melilotus: finely serrate / dentate
|
| Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk)  inherited by genus Melilotus: with

| Flower colour: (i)Attention: assess colour of the most colourful parts of the flower, but not of the stamens; be aware of single plants with a mutation (mostly white) on flower colour. | yellow to orange (i)Pale to golden yellow
example: Ranunculus, Crepis
|
| 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)
example: Parnassia   inherited by family Fabaceae: double, different
|
| 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 ? Veronica | papilionaceous (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: Fabaceae, Silene   inherited by family Fabaceae: fused
|

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
example: Caragana, Petasites inherited by family Fabaceae: fused with each other
|
| Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil). | 1 (i)One carpel, but clearly one stigma
