Habitat:Waterside shrubberies, birch and elm forests and groves (Grubov 2001).
Habit (i)general appearance of a plant
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 Convallariaceae: no parasite/saprophyte
Water or terrestrial plant: (i)Where do the plants grow?terrestrial (i)Plant grows on dry land
example: Orostachys spinosa
inherited by family Convallariaceae: terrestrial
Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)
Leaf development: (i)Structure and development of leaves.flattened blade (i)Cross-section of lamina flat, plain inherited by family Convallariaceae: flattened blade
common leaf (i)Green, often divided in blade and petiole
example: Cotoneaster
inherited by family Convallariaceae: common leaf
with green leaves (i)Plant with green leaves inherited by family Convallariaceae: 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
inherited by genus Maianthemum: 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.simple (i)Non-divided leaf, but margin may be incised nearly to the ground inherited by genus Maianthemum: simple
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 inherited by family Convallariaceae: lanceolate
cordate (i)Heart shaped
example: Cortusa
inherited by genus Maianthemum: cordate
Length of leaves: (i)How long is the leaf, be carefull in compound leaves, measure the complete leaf. from 6 mm to 10 mm inherited by genus Maianthemum:
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
inherited by family Convallariaceae: entire
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.
inherited by order Asparagales: parallel
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 Convallariaceae: 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
inherited by genus Maianthemum: white
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
inherited by family Convallariaceae: simple, similar
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 Convallariaceae: radiary, regular (actinomorphic)
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
inherited by family Convallariaceae: simple (flat) - Do not confuse with inflorescences as in some Asteraceae
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 Convallariaceae: no spur
Stamen number: (i)Attention: We ask for the reproductive organs of the flower dispersing pollen. Count only fully fertile stamens, not staminodia (e.g. Parnassia).6 (i)
example: Veratrum, Smelowskia, Juncus
inherited by family Convallariaceae: 6
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 Convallariaceae: free
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
inherited by family Convallariaceae: superior (hypogynous)
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.
Type of fruit: (i)Common fruit types (including pseudocarp).Indehiscent fruits inherited by genus Maianthemum: Indehiscent fruits
Solitary fruits (i) inherited by genus Maianthemum: Solitary fruits
berry (i)Fleshy fruit with several to many seeds in the flesh
example: Tomato
inherited by genus Maianthemum: berry
Size of fruit: (i)Size of the fruit including appendage. to 5 mm (i)
example: Halerpestes: many folicles forming dry nutlets
inherited by genus Maianthemum:
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 Asparagales: homorhizous
Storage in below-ground structures: (i)Rhizomes or bulbs.storage rhizomes (i)Horizontal, root like structures with scale leaves or their scars, these clearly thicker than the bases of above-ground shoots
example: Petasites, Iris
inherited by family Convallariaceae: storage rhizomes
