Habitat: | Stony and debris steppe and desert slopes of mountains and hills, waterside pebbles and bottom of sayrs, as well as half-weed in field balks and along irrigation ditches, in crops and abandoned fields (Grubov 2001). |
Habit (i)general appearance of a plant | |
Growth form: (i)Herb, shrub, tree or climber. | annual (i)Completing its life cycle within one year or one growing season; roots weak and thin inherited by genus Hyoscyamus: annual biennial (i)Taking two years from seedling stage to maturity, seed-set and death; often only with a rosette of leaves in the first year inherited by genus Hyoscyamus: biennial 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 genus Hyoscyamus: herb
|

|
Leaf arrangement: (i)Arrangement of leaves at the stem. | alternate (i)One leaf per node; distiche: arranged in two vertical rows, equitant example: Phragmites inherited by family Solanaceae: alternate

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 Solanaceae: 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 Solanaceae: 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 Solanaceae: 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 Solanaceae: simple (flat) - Do not confuse with inflorescences as in some Asteraceae tubular to funnel-shaped (i)Petals form a tube, are often partially united to a cylindrical corolla, often surrounded by a calyx inherited by genus Hyoscyamus: tubular to funnel-shaped campanulate (i)Petals united to a bell-shaped corolla inherited by family Solanaceae: campanulate
|
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 Solanaceae: 5
|
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! | fused (i)Leaves united, only tips are free example: Fabaceae, Silene inherited by family Solanaceae: fused
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla inherited by family Solanaceae: 5
|
Petal / Tepal fusion: (i)To which degree are the petal leaves connected? Petals sympetalous. | fused (i)petal leaves united, only tips are free (gamopetalous, sympetalous) example: Linnaea, Adenophora, Stellera inherited by family Solanaceae: 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 Solanaceae: 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 Solanaceae: 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. | free (i)Stamens with separate bases example: Malus inherited by family Solanaceae: free
|
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 inherited by family Solanaceae: 1
|
Carpel number: (i)Number of carpels (carpel: forming a simple pistil or part of a compound pistil, modified leaf). | 2 inherited by family Solanaceae: 2
|
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 Solanaceae: fused
|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Solanaceae: 1
|
Stigma number per style: (i)Number of stigmas per style. | 1 (i)One stigma, sessile or with a developed style inherited by family Solanaceae: 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 example: Delphinium, Anemone inherited by family Solanaceae: 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 Solanaceae: 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. | |
Type of fruit: (i)Common fruit types (including pseudocarp). | Solitary fruits (i) inherited by genus Hyoscyamus: Solitary fruits capsule (i)Dry dehiscent fruit, releasing seeds by slits or holes. example: Poppy, most Caryophyllaceae, Cerastium, a lot of Scrophulariaceae, Iris (oppened capsule looks like Delphinium), Zygophyllum - it is a very common fruit type inherited by genus Hyoscyamus: capsule Dehiscent fruits (i)Fruits open along a longitudinale line (except silicula) inherited by genus Hyoscyamus: Dehiscent fruits
|
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 Solanales: allorhizous
|
Distribution (i)region where the plant is likely to be found | |
