| species: 1 |
| 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
tree (i)Woody plant with a clear main trunk, at least 2-3 m tall
example: Ulmus pumila 
|
| 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. | opposite, opposite-decussate (i)Two leaves per node
example: Lamiaceae, e.g. Phlomis  
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.) 
|
| 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 
|
| 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
|
| 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
|
| 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
|
| 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  
|
| Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis | |
| Inflorescence: (i)Structure of the inflorescence. | Solitary flowers (i)Each flower grows on an own leafy stem there may be more than one, if the plant has many leafy shoots
example: Viola, Saxifraga hirculus, Rubus arcticus
|
| 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
|
| Type of fruit: (i)Common fruit types (including pseudocarp). | Indehiscent fruits
Solitary fruits (i)   
achene (i)A small, dry, indehiscent fruit with a single seed
example: Asteraceae, Apiaceae (schizocarp), Dipsacaceae, Rosaceae, Ranunculaceae  
berry (i)Fleshy fruit with several to many seeds in the flesh
example: Tomato 
nut or nutlet (i)Dry fruit with a single, hard stone inside (and usually a large often edible embryo) 
drupe (stone fruit) (i)Fleshy, indehiscent fruit with a single, hard stone inside
example: Plum, cherry 
|
| 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)
Flying (wind dispersed) (i)Fruits or seeds with appendages to fly
example: Taraxacum, Atraphaxis, Pulsatilla
Otherwise (i)All parts dry, no conspicuous adaptations
|
| 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
