Habit (i)general appearance of a plant | |
Growth form: (i)Herb, shrub, tree or climber. | shrub, subshrub or semishrub (i)Shrub, multi-stemmed, mostly (0.2) 0.5 - 5 m high, shoots woody up to the tip example: Caragana leucophloea inherited by family Nitrariaceae: shrub, subshrub or semishrub
|
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 Nitrariaceae: 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 Nitrariaceae: 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 inherited by family Nitrariaceae: with green leaves fleshy leaf (i)Leaves more or less thick, juicy, terete or flat example: Crassulaceae inherited by family Nitrariaceae: fleshy leaf
|
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 inherited by family Nitrariaceae: whorled or fascicled
|
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 Nitrariaceae: simple
|
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 inherited by family Nitrariaceae: entire
|
Stipule: (i)Leaflets at the base of the petiole, these are smaller and of different shape. | pair (i)A pair of free stipulae example: Lathyrus, Trifolium inherited by family Nitrariaceae: pair
|
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 Nitrariaceae: 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. | 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 inherited by family Nitrariaceae: greenish white (i)Most plants of the population white example: Pleurospermum, Maianthemum inherited by family Nitrariaceae: white yellow to orange (i)Pale to golden yellow example: Ranunculus, Crepis inherited by family Nitrariaceae: yellow to orange
|
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 Nitrariaceae: 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 Nitrariaceae: radiary, regular (actinomorphic)
|
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 inherited by family Nitrariaceae: simple (flat) - Do not confuse with inflorescences as in some Asteraceae
|
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 Nitrariaceae: 5
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla inherited by family Nitrariaceae: 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 Nitrariaceae: 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 Nitrariaceae: 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 Nitrariaceae: 10 > 10 (i) example: Nymphaea, Callianthemum, Rosa inherited by family Nitrariaceae: > 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 Nitrariaceae: free
|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Nitrariaceae: 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 Nitrariaceae: 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 Nitrariaceae: bisexual, hermaphrodite
|
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). | Indehiscent fruits inherited by family Nitrariaceae: Indehiscent fruits Solitary fruits (i) inherited by family Nitrariaceae: Solitary fruits drupe (stone fruit) (i)Fleshy, indehiscent fruit with a single, hard stone inside example: Plum, cherry inherited by family Nitrariaceae: drupe (stone fruit)
|
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). | 1 (i)A single seed (stone) or seed and fruit wall tightly connected example: Prunus, Amygdalus: drupe inherited by family Nitrariaceae: 1
|
Shoot/Stem (i)a young stem or branch | |
Spines, thorns or prickles: (i)Shoot with conspicuous spines, thorns or prickles. | spines or thornes (i)Sharp pointed woody structure originating from the plant (thornes derived from a reduced branch, spines from leaves) example: Prunus spinosa no in Mongolia
|
Root / shoot below ground (i)plant part below ground (in most cases), including below ground shoots, without leaves | |
Root type: (i)Organisation of the roots. | allorhizous (i)Plant with a conspicuous tap root, one larger tap root with side roots example: Dicotyledonae inherited by order Sapindales: allorhizous
