example: Ranunculus, Crepis inherited by genus Ranunculus: yellow to orange
|
| 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 Ranunculus: radiary, regular (actinomorphic)
|
| 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 inherited by genus Ranunculus: > 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
|
| Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil). | >8 (i)Many stigmas, often a whole bunch densily packed
example: Ranunculus, Rubus, Papaver inherited by genus Ranunculus: >8
|
| 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)
|

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. | |

Solitary fruits (i)    inherited by genus Ranunculus: Solitary fruits
follicle (i)A pod arising from a single carpel, opening along a single side (the inner suture to which the seeds are attached)    inherited by genus Ranunculus: follicle
nut or nutlet (i)Dry fruit with a single, hard stone inside (and usually a large often edible embryo)  inherited by genus Ranunculus: 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

| Hairs | |
| Has hairs?: | no hairs, glabrous inherited by genus Ranunculus: no hairs, glabrous

| 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
