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 perennial (i)Living for several to many years, as opposed to annual and biennial
|
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
|
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 Trilliaceae: no parasite/saprophyte
|
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. | flattened blade (i)Cross-section of lamina flat, plain inherited by family Trilliaceae: flattened blade common leaf (i)Green, often divided in blade and petiole example: Cotoneaster inherited by family Trilliaceae: common leaf with green leaves (i)Plant with green leaves
|
Leaf arrangement: (i)Arrangement of leaves at the stem. | whorled or fascicled (i)Three or more leaves per node or leaves crowded. example: Galium, Nitraria
|
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 lanceolate (i)Lance-shaped; much longer than wide, with the widest point in the middle or below
|
Length of leaves: (i)How long is the leaf, be carefull in compound leaves, measure the complete leaf. | more than 50 mm
|
Leaf apex: (i)Appearance of the tip of leaf resp. leaflets in compound leaves. | 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? | entire (i)Plain margin, not toothed example: Iris
|
Leaf base: (i)The angle the leaf blade forms with a real or imaginary (sessile leaves) petiole. Attention: Here, we consider only the base of leaves or leaflets (in case of compound leaves). | cuneate (i)Tapering gradually, angle > 90° - 120° example: Thalictrum, Betula fruticosa
|
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 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. | greenish (i)petals absent or not distinctly different from colours of leaves, only stigmas (white) or anthers (yellow) may differ in color example: Chenopodium, Triglochin
|
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 Trilliaceae: simple, similar 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 Trilliaceae: 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
|
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
|

|
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 Trilliaceae: 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 10 (i) example: Silene
|
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). | 1 (i)One carpel, but clearly one stigma example: Pyrola, Primula, Alyssum

|
Stigma number per style: (i)Number of stigmas per style. | > 3 (i)More than three stigmas, resulting from more than three fused carpels with or without develped style
|
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
|
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
