genus: 1
species: 3
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

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?water or swamp plant
aquatic, submerged (i)Completely submerged water plant, onlys flowers may appear at the surface
example: Zannichellia

Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)
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?filiform (i)Leaves thread-like, at least more than ten times longer than broad
example: Potamogeton pectinatus, P. filiformis

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?entire (i)Plain margin, not toothed
example: Iris

Leaf veination: (i)Arrangement of the main veins of a leaf.parallel (i)Most veins arranged parallel to the length of leaf, mostly no pronounced main vein (usually in elongate to linear leaves)
example: Most Monocotyledonae, Plantago, Veratrum, a lot of Caryophyllaceae looks like that.

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

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.absent or strongly reduced (i)No perianth leaves ensheathing stamen and/or carpels
example: Callitriche

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

Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured).none or reduced (i)But green sepals may exist
example: Thalictrum

Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing spur (i)Flower without appendage
example: Peganum

Ovary position: (i)For entirely or partly fused carpels, describe their position in relation to the insertion point of perianth leaves (best done by doing a longitudinal section of a flower).superior (hypogynous) (i)Base of carpels attached above insertion point of perianth leaves, carpels free or fused
example: Delphinium, Anemone

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

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.homorhizous (i)Many equal roots
example: Monocotyledonae
inherited by order Alismatales: homorhizous
