| Habitat: | Slopes of hollows, steppe shrubberies, steppe rocky and stony slopes, rocks (Grubov 2001). |
| Habit (i)general appearance of a plant | |
| Growth form: (i)Herb, shrub, tree or climber. | shrub, subshrub or semishrub (i)Shrub, multi-stemmed, mostly (0.2) 0.5 - 5 m high, shoots woody up to the tip
example: Caragana leucophloea 
|
| 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
from 600 mm to 1000 mm
from 1000 mm to 3000 mm
|
| 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 Rosaceae: no parasite/saprophyte
|
| Water or terrestrial plant: (i)Where do the plants grow? | terrestrial (i)Plant grows on dry land
example: Orostachys spinosa
|
| Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades) | |
| Leaf development: (i)Structure and development of leaves. | with green leaves (i)Plant with green leaves inherited by family Rosaceae: with green leaves
|
| Leaf arrangement: (i)Arrangement of leaves at the stem. | alternate (i)One leaf per node; distiche: arranged in two vertical rows, equitant
example: Phragmites  
|
| 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 
|
| 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? | elliptic (including ovate and obovate) (i)Elliptic: broadest at the middle and narrower at the two equal ends; ovate: egg-shaped, attached at the broad end; obovate: attached at the narrower end
example: Limosella aquatica 
|
| Length of leaves: (i)How long is the leaf, be carefull in compound leaves, measure the complete leaf. | from 21 mm to 50 mm
more than 50 mm
|
| Leaf apex: (i)Appearance of the tip of leaf resp. leaflets in compound leaves. | acuminate (i)Gradually tapering to a (sharp) point
example: Populus laurifolia? 
|
| 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
example: Pedicularis 
|
| Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk) 
|
| Stipule: (i)Leaflets at the base of the petiole, these are smaller and of different shape. | pair (i)A pair of free stipulae
example: Lathyrus, Trifolium  inherited by genus Armeniaca: pair
|
| Flower (i)reproductive portion of the plant, consisting of sepals, petals, stamens, and pistils | |
| Flower appearance and pollination: (i)General appearance of the flower. | attractive, animal-pollinated (i)attractive and coloured flowers, mostly large, attracting surely animals
example: Trollius, Rosa, Chamaerhodos inherited by family Rosaceae: attractive, animal-pollinated
|
| 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. | white (i)Most plants of the population white
example: Pleurospermum, Maianthemum
|
| 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 genus Armeniaca: 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. | radiary, regular (actinomorphic) (i)More than two axis of symmetry
example: Saxifraga: 5; Iris: 3  inherited by family Rosaceae: radiary, regular (actinomorphic)
|
| Flower form: (i)common forms of flowers ? Veronica | simple (flat) - Do not confuse with inflorescences as in some Asteraceae (i)Petals spread out, flower appearing flat
example: Mollugo, Trientalis, Pulsatilla, Saxifraga  inherited by family Rosaceae: simple (flat) - Do not confuse with inflorescences as in some Asteraceae
|
| 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 genus Armeniaca: 5
|
| Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i)

|
| Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing nectar. | no spur (i)Flower without appendage
example: Peganum inherited by family Rosaceae: no spur
|
| 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. | free (i)Stamens with separate bases
example: Malus inherited by family Rosaceae: free
|
| Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis | |
| Inflorescence: (i)Structure of the inflorescence. | Solitary flowers (i)Each flower grows on an own leafy stem there may be more than one, if the plant has many leafy shoots
example: Viola, Saxifraga hirculus, Rubus arcticus inherited by genus Armeniaca: Solitary flowers
|
| Fruit (i)the seed bearing organ, with or without adnate parts; a ripened ovary and any other structures which are attached and ripen with it. Aggregate fruits are handled like simple fruits for determination. | |
| Consistency: (i)Fleshy fruits or dry fruits, see dispersal adaptations for further classification. | dry (i)With a dry outer shell, no fleshy parts, but seed (embryo) could be edible
|
| Type of fruit: (i)Common fruit types (including pseudocarp). | Indehiscent fruits inherited by genus Armeniaca: Indehiscent fruits
Solitary fruits (i)    inherited by genus Armeniaca: Solitary fruits
