| genus: 1 |
| species: 8 |
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
|
Special growth forms or habits: | rosette plant (i)All or nearly all leaves in a basal rosette, only inflorescences on erect stalks, these without or with much smaller leaves example: Primula farinosa
|
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 arrangement: (i)Arrangement of leaves at the stem. | basal rosette (i)Leaves positioned at the base of the stem; stem often without leaves, no visible internodes (but flowers often on erect stems, and these may have few leaves) example: Limonium, Potentilla, Plantago; also used in Liliales with basaly crouwded leaves (Tofieldia, Zigadenus etc.)
|
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
|
Leaf apex: (i)Appearance of the tip of leaf resp. leaflets in compound leaves. | obtuse (i)Sides coming together at the apex at an angle greater than 90 degrees example: Fallopia convolvulus 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 entire (i)Plain margin, not toothed example: Iris
|
Stipule: (i)Leaflets at the base of the petiole, these are smaller and of different shape. | none (i)Without stipules example: Euphorbia, Ericaceae s.l.
|
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. | 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
|
Diameter of flower: (i)Diameter of flower or flower head. | to 5 mm (i) example: Aruncus from 5 mm to 10 mm (i) example: Stellaria
|
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 ? Veronica | tubular to funnel-shaped (i)Petals form a tube, are often partially united to a cylindrical corolla, often surrounded by a calyx
|
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. | 4 (i) example: Sinapis
|
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! | free (i)All leaves separate from each other example: Geranium
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 4 (i) example: Galium
|
Petal / Tepal fusion: (i)To which degree are the petal leaves connected? Petals sympetalous. | fused at base (i)petal leaves with a joint base, but fused over not more than 50% of the entire length example: Myosotis, Pedicularis, Cortusa
|
Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing nectar. | no spur (i)Flower without appendage example: Peganum
|
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). | 4 (i)Extremely rare, may be absent example: Plantago
|
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
|
Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil). | 2 (i)Two stigmas, often cleaved like a snakes tongue example: Salvia, Arnica, Bupleurum, Bromus, Saxifraga, Veronica
|
Carpel fusion: (i)To which degree are the carpels (modified leaf forming simple pistil or part of a compound pistil) fused. | fused (i)Carpels united into an ovary, only styles are free example: Malus, Berberis
|
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 type: (i)Types of inflorescence. Attention: We here ask for the botanical nomenclature of inflorescences, which is sufficiently complicated. Tick only, if you are certain, or tick all inflorescence types that appear similar of these of the plant in question. | spike (spadix) (i)All flowers sessile and crowded along a main axis, there may be several spikes on a shoot; sometimes axis thickened (spadix) example: Plantago, Carex vesicaria, Vicia, Typha (spadix)
