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

inherited by family Ranunculaceae: 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.simple, similar (i)Only one type of perianth leaves (tepals)
example: Tulipa
inherited by genus Clematis: simple, similar
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 genus Clematis: radiary, regular (actinomorphic)
Flower form: (i)common forms of flowers ? Veronicasimple (flat) - Do not confuse with inflorescences as in some Asteraceae (i)Petals spread out, flower appearing flat
example: Mollugo, Trientalis, Pulsatilla, Saxifraga
inherited by genus Clematis: simple (flat) - Do not confuse with inflorescences as in some Asteraceae
Sepal fusion: (i)To which degree are the sepal leaves connected? 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!free (i)All leaves separate from each other
example: Geranium
inherited by family Ranunculaceae: free
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 Ranunculaceae: free
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
inherited by family Ranunculaceae: > 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 Ranunculaceae: free
Carpel number: (i)Number of carpels (carpel: forming a simple pistil or part of a compound pistil, modified leaf).> 5 inherited by family Ranunculaceae: > 5
Carpel fusion: (i)To which degree are the carpels (modified leaf forming simple pistil or part of a compound pistil) fused.free (i)Carpels entirely free
example: Geum, Aconitum
inherited by family Ranunculaceae: 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).superior (hypogynous) (i)Base of carpels attached above insertion point of perianth leaves, carpels free or fused
example: Delphinium, Anemone
inherited by order Ranunculales: 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 Ranunculaceae: 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.
Consistency: (i)Fleshy fruits or dry fruits, see dispersal adaptations for further classification.dry (i)With a dry outer shell, no fleshy parts, but seed (embryo) could be edible inherited by family Ranunculaceae: dry
Type of fruit: (i)Common fruit types (including pseudocarp).Indehiscent fruits inherited by genus Clematis: Indehiscent fruits

inherited by genus Clematis: achene
nut or nutlet (i)Dry fruit with a single, hard stone inside (and usually a large often edible embryo) inherited by genus Clematis: nut or nutlet
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
inherited by family Ranunculaceae: opening along dehiscent line
opening / dehiscent (i)Dry? Fruits opening with different types inherited by family Ranunculaceae: opening / dehiscent
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 Ranunculales: allorhizous
Runners: (i)Plant must be excavated; shoots, subterranean shoots connected by runners.none (i)No runners or stolos visible
example: Dactylorhiza
inherited by family Ranunculaceae: none
long root suckers or rhizomes (i)Plants grow new shoots from roots or subterranean shoots, called rhizomes, these spacing stems apart
example: Hippophae, Artemisia sericea
inherited by family Ranunculaceae: long root suckers or rhizomes
stolons (i)Plants creep with above-ground shoots (stolons) which can root and establish new plants
example: Potentilla arenaria, P. anserina
inherited by family Ranunculaceae: stolons
Storage in below-ground structures: (i)Rhizomes or bulbs.none (i)Plant with non-thickened roots, their maximum diameter does not exceed the diameter of the shoot base
example: Anabasis brevifolia
inherited by family Ranunculaceae: none
storage rhizomes (i)Horizontal, root like structures with scale leaves or their scars, these clearly thicker than the bases of above-ground shoots
