| species: 2 |
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
|
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 Rosaceae: no parasite/saprophyte
|
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 Rosaceae: with green leaves
|
Leaf arrangement: (i)Arrangement of leaves at the stem. | basal rosette (i)Leaves positioned at the base of the stem; stem often without leaves, no visible internodes (but flowers often on erect stems, and these may have few leaves) example: Limonium, Potentilla, Plantago; also used in Liliales with basaly crouwded leaves (Tofieldia, Zigadenus etc.)
|
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
|
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 Rosaceae: attractive, animal-pollinated
|
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
|
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 Rosaceae: 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 Rosaceae: simple (flat) - Do not confuse with inflorescences as in some Asteraceae
|
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. | free (i)all petal leaves separate from each other example: Anthriscus inherited by family Rosaceae: 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 Rosaceae: 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: Nymphaea, Callianthemum, Rosa
|
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 Rosaceae: free
|
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. | |
Consistency: (i)Fleshy fruits or dry fruits, see dispersal adaptations for further classification. | fleshy (i)Usually non dehiscent; with a fleshy (swollen because of a high water content) outer shell, flesh edible at least for animals example: Prunus, Amygdalus, Malus
|
Dispersal: (i)Appearance of fruit or seed (if single) and adaptations to dispersal. | Fleshy, edible (i)At least parts with a soft tissue edible at least for some animals (not necessarily for humans)
|
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 Rosales: allorhizous
