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 Onagraceae: herb
|
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 Onagraceae: no parasite/saprophyte

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. | simple (i)Non-divided leaf, but margin may be incised nearly to the ground inherited by family Onagraceae: 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? | 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 linear incl.grasslike or oblong (i)Leaves more than two times longer than broad with more or less parallel margins; see character: stipule for ligula example: Dracocephalum ruyschiana, Poaceae, Scutellaria scordifolia, Pinus
|
Petiole: (i)Leaf divided into stalk (petiole) and blade. | without (i)Leaves without petiole (stalk), sessile example: Poaceae, Iris

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 purple to violet (i)All colors between purple and violet, often changing with flower age example: Pulmonaria
|
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 Onagraceae: double, different
|
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 Onagraceae: radiary, regular (actinomorphic) zygomorphic (i)One axis of symmetry, monosymmetrical flowers example: Pedicularis, Nepeta, Viola
|
Flower form: (i)common forms of flowers ? Veronica | simple (flat) - Do not confuse with inflorescences as in some Asteraceae (i)Petals spread out, flower appearing flat example: Mollugo, Trientalis, Pulsatilla, Saxifraga
|
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
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 4 (i) example: Galium
|
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 Onagraceae: 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). | 7-9 (i) example: Trientalis, Sedum
|
Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil). | 1 (i)One carpel, but clearly one stigma example: Pyrola, Primula, Alyssum inherited by family Onagraceae: 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). | intermediate ovary (i)Ovary partly or fully underneath the perianth leaves, ovary not fused with axis but surrounded by a flower cup example: Prunus, a lot of Rosaceae inherited by family Onagraceae: intermediate ovary inferior (i)Ovary below the point where perianth leaves are inserted, always fused to an ovary example: Vaccinum inherited by family Onagraceae: inferior
|
Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis | |
Inflorescence: (i)Structure of the inflorescence. | Flowers in inflorescence (i)No solitary flowers Simple inflorescences (i)Flowers sessile on a main shoot or on short to long not branched side shoots example: Polygonum bistorta
|
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
|
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). | Solitary fruits (i) capsule (i)Dry dehiscent fruit, releasing seeds by slits or holes. example: Poppy, most Caryophyllaceae, Cerastium, a lot of Scrophulariaceae, Iris (oppened capsule looks like Delphinium), Zygophyllum - it is a very common fruit type Dehiscent fruits (i)Fruits open along a longitudinale line (except silicula)
|
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 / dehiscent (i)Dry? Fruits opening with different types
|
Seed number: (i)Estimate the number of seeds per fruit, if recognizable seeds are in the fruit (in rare cases a fruit may contain one seeded nuts: rose hip, carex). | 7-50 (i)Numerable, but may be counted example: Vaccinum: multi-seeded berry, Ptilotrichum: few-seeded siliqua
|
