| species: 1 |
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 inherited by family Rutaceae: herb perennial (i)Living for several to many years, as opposed to annual and biennial inherited by family Rutaceae: perennial
|
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
|
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 Rutaceae: 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 Rutaceae: terrestrial
|
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 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. | imparipinnate / ottpinnate (i)A pinnate leaf with an central unpaired terminal leaflet compound (i)Composed of several similar parts pinnate (i)With leaflets on both sides of an axis, at least 2 pairs or more example: Onobrychis
|
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)
|
Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk) inherited by family Rutaceae: with
|
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. inherited by family Rutaceae: none
|
Leaf veination: (i)Arrangement of the main veins of a leaf. | pinnate (i)One main vein, several side veins, sometimes inconspicuous example: Cicerbita inherited by family Rutaceae: pinnate
|
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 Rutaceae: 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. | pink (i)Between red and white example: Centaurium
|
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 family Rutaceae: double, different
|
Diameter of flower: (i)Diameter of flower or flower head. | more than 40 mm (i) example: Incarvillea, Cypripedium
|
Flower symmetry: (i)Symmetry of the perianth leaves. Attention: to assess this character, look on sepals, petals and stamens, but neglect carpels and ovary. | zygomorphic (i)One axis of symmetry, monosymmetrical flowers example: Pedicularis, Nepeta, Viola
|
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 family Rutaceae: 5
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla inherited by family Rutaceae: 5
|
Petal / Tepal fusion: (i)To which degree are the petal leaves connected? Petals sympetalous. | free (i)all petal leaves separate from each other example: Anthriscus inherited by family Rutaceae: free
|
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 Rutaceae: 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). | 10 (i) example: Silene inherited by family Rutaceae: 10
|
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 Rutaceae: free
|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Rutaceae: 1

Appearance: (i)Outer look of the inflorescence. | terminal (i)Inflorescence is the highest point of the plant and may consist of a single flower only example: Cypripedium, Rhaponticum, Ligularia sibirica, Echinops inherited by family Rutaceae: terminal
|
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. | raceme (i)Stalked flowers arranged along a simple main axis, often one by one in the axils of leaves, maturing from bottom upwards example: Aconitum barbatum
|
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. | |
