Habitat:Bottom of canyons, near springs (Grubov 2001).
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

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.imparipinnate / ottpinnate (i)A pinnate leaf with an central unpaired terminal leaflet inherited by genus Rosa: imparipinnate / ottpinnate
compound (i)Composed of several similar parts inherited by genus Rosa: compound
pinnate (i)With leaflets on both sides of an axis, at least 2 pairs or more
example: Onobrychis
inherited by genus Rosa: pinnate
Petiole: (i)Leaf divided into stalk (petiole) and blade.with (i)Leaves with petiole (stalk) inherited by genus Rosa: with
Stipule: (i)Leaflets at the base of the petiole, these are smaller and of different shape.pair (i)A pair of free stipulae

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
inherited by genus Rosa: 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

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
inherited by genus Rosa: 5
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured).5 (i)
example: Potentilla
inherited by genus Rosa: 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 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
inherited by genus Rosa: > 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

inherited by family Rosaceae: free
Carpel number: (i)Number of carpels (carpel: forming a simple pistil or part of a compound pistil, modified leaf).> 5 inherited by genus Rosa: > 5

example: Vaccinum
inherited by genus Rosa: inferior
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 genus Rosa: bisexual, hermaphrodite
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

example: Cypripedium, Rhaponticum, Ligularia sibirica, Echinops
inherited by genus Rosa: terminal
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: Corylus (nut), Vaccinium (berry)
inherited by genus Rosa: not opening / indehiscent
