Habitat:Rocky and shady canyons and creek valleys (Grubov 2001).
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
inherited by family Asclepiadaceae: herb
Smell & Touch: (i)General appearance of the plant.abundant milky juice (latex) (i)Shoots and often leaves contain white or yellowish latex

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 Asclepiadaceae: with green leaves
Leaf arrangement: (i)Arrangement of leaves at the stem.opposite, opposite-decussate (i)Two leaves per node

inherited by family Asclepiadaceae: opposite, opposite-decussate
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.simple (i)Non-divided leaf, but margin may be incised nearly to the ground inherited by family Asclepiadaceae: simple
Petiole: (i)Leaf divided into stalk (petiole) and blade.with (i)Leaves with petiole (stalk) inherited by family Asclepiadaceae: with
Stipule: (i)Leaflets at the base of the petiole, these are smaller and of different shape.none (i)Without stipules
example: Euphorbia, Ericaceae s.l.
inherited by family Asclepiadaceae: none
Leaf veination: (i)Arrangement of the main veins of a leaf.pinnate (i)One main vein, several side veins, sometimes inconspicuous
example: Cicerbita
inherited by family Asclepiadaceae: pinnate
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 Asclepiadaceae: 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 family Asclepiadaceae: 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
example: Saxifraga: 5; Iris: 3
inherited by family Asclepiadaceae: radiary, regular (actinomorphic)
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 family Asclepiadaceae: 5
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured).5 (i)
example: Potentilla
inherited by family Asclepiadaceae: 5
Petal / Tepal fusion: (i)To which degree are the petal leaves connected? Petals sympetalous.fused at base (i)petal leaves with a joint base, but fused over not more than 50% of the entire length
example: Myosotis, Pedicularis, Cortusa
inherited by family Asclepiadaceae: fused at base
fused (i)petal leaves united, only tips are free (gamopetalous, sympetalous)
example: Linnaea, Adenophora, Stellera
inherited by family Asclepiadaceae: fused
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 Asclepiadaceae: 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).5 (i)
example: Peucedanum
inherited by family Asclepiadaceae: 5
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.fused with each other (i)All or most stamens fused with each other to a tube-like structure
example: Caragana, Petasites
inherited by family Asclepiadaceae: fused with each other
Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil).1 (i)One carpel, but clearly one stigma
example: Pyrola, Primula, Alyssum

Carpel fusion: (i)To which degree are the carpels (modified leaf forming simple pistil or part of a compound pistil) fused.fused (i)Carpels united into an ovary, only styles are free
example: Malus, Berberis
inherited by family Asclepiadaceae: fused
Style number: (i)Portion of the pistil connecting the stigma to the ovary.1 inherited by family Asclepiadaceae: 1
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

Inflorescence: (i)Structure of the inflorescence.Flowers in inflorescence (i)No solitary flowers inherited by family Asclepiadaceae: Flowers in inflorescence
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 Asclepiadaceae: dry
Type of fruit: (i)Common fruit types (including pseudocarp).Solitary fruits (i) inherited by family Asclepiadaceae: 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 family Asclepiadaceae: follicle
Dehiscent fruits (i)Fruits open along a longitudinale line (except silicula) inherited by family Asclepiadaceae: Dehiscent fruits
