genus: 14
species: 70
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

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

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
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
Leaf veination: (i)Arrangement of the main veins of a leaf.pinnate (i)One main vein, several side veins, sometimes inconspicuous
example: Cicerbita

Flower (i)reproductive portion of the plant, consisting of sepals, petals, stamens, and pistils
Flower appearance and pollination: (i)General appearance of the flower.not attractive, wind-pollinated or some water plants (i)Small, colourless or green flowers
example: Betula, grasslike plants: Carex, Setaria, Juncus

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.greenish (i)petals absent or not distinctly different from colours of leaves, only stigmas (white) or anthers (yellow) may differ in color
example: Chenopodium, Triglochin

red (i)Reddish (also orange) to deep red
example: Lilium, Rhododendrum

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.simple, similar (i)Only one type of perianth leaves (tepals)
example: Tulipa

Diameter of flower: (i)Diameter of flower or flower head. from 5 mm to 10 mm (i)
example: Stellaria

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.radiary, regular (actinomorphic) (i)More than two axis of symmetry
example: Saxifraga: 5; Iris: 3

Flower form: (i)common forms of flowers ? Veronicasimple (flat) - Do not confuse with inflorescences as in some Asteraceae (i)Petals spread out, flower appearing flat
example: Mollugo, Trientalis, Pulsatilla, Saxifraga

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.3 (i)
example: Baldellia, Alisma

Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing nectar.no spur (i)Flower without appendage
example: Peganum

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
Solitary fruits (i)
nut or nutlet (i)Dry fruit with a single, hard stone inside (and usually a large often edible embryo)
Seed number: (i)Estimate the number of seeds per fruit, if recognizable seeds are in the fruit (in rare cases a fruit may contain one seeded nuts: rose hip, carex).1 (i)A single seed (stone) or seed and fruit wall tightly connected
example: Prunus, Amygdalus: drupe

Root / shoot below ground (i)plant part below ground (in most cases), including below ground shoots, without leaves
Root type: (i)Organisation of the roots.allorhizous (i)Plant with a conspicuous tap root, one larger tap root with side roots
example: Dicotyledonae
inherited by order Caryophyllales: allorhizous
