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 Scrophulariaceae: herb
|
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 inherited by family Scrophulariaceae: 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. | simple (i)Non-divided leaf, but margin may be incised nearly to the ground
|
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
|
Petiole: (i)Leaf divided into stalk (petiole) and blade. | without (i)Leaves without petiole (stalk), sessile example: Poaceae, 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. | 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. | attractive, animal-pollinated (i)attractive and coloured flowers, mostly large, attracting surely animals example: Trollius, Rosa, Chamaerhodos inherited by family Scrophulariaceae: 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. | yellow to orange (i)Pale to golden yellow example: Ranunculus, Crepis
|
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 Scrophulariaceae: double, different

|
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
|
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! | fused (i)Leaves united, only tips are free example: Fabaceae, Silene
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla
|
Petal / Tepal fusion: (i)To which degree are the petal leaves connected? Petals sympetalous. | fused (i)petal leaves united, only tips are free (gamopetalous, sympetalous) example: Linnaea, Adenophora, Stellera inherited by family Scrophulariaceae: fused
|
Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing nectar. | one (i)One leaf with a spur example: Linaria, Delphinium
|
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. | fused with a corolla (calyx in Thymelaeaceae) (i)Stamens with perianth leaves at least one third of the length of the filament example: Orobanche, Salvia, Stellera inherited by family Scrophulariaceae: fused with a corolla (calyx in Thymelaeaceae)
|

|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Scrophulariaceae: 1
|
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 Scrophulariaceae: superior (hypogynous)
|
Sex: (i)Distribution of male and female organs among flowers, only most commonly cases. | bisexual, hermaphrodite (i)All or nearly all flowers of a plant with male and female parts example: Haplophyllum, Chenopodium inherited by family Scrophulariaceae: bisexual, hermaphrodite

Inflorescence: (i)Structure of the inflorescence. | Flowers in inflorescence (i)No solitary flowers
|
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
|
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

|
Opening of fruit: (i)Mode of dehiscence at maturity to release seeds. | opening along dehiscent line (i)Opening along a preformed line example: Vicia, Lathyrus: pods opening with valves (i)Capsules, siliqua, pods or follicles; opening with two or more dehiscent lines and split off outer parts as valves example: Alyssum, Arabis: siliqua, Epilobium: four-valved capsule, Arenaria: capsule with three valves. opening with pores (i)The seed capsule opens with holes example: Papaver, Campanula opening / dehiscent (i)Dry? Fruits opening with different types
