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 Menyanthaceae: 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 Menyanthaceae: 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 Menyanthaceae: 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 Menyanthaceae: 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 family Menyanthaceae: 5
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla inherited by family Menyanthaceae: 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 Menyanthaceae: 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 Menyanthaceae: 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 Menyanthaceae: 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 a corolla (calyx in Thymelaeaceae) (i)Stamens with perianth leaves at least one third of the length of the filament example: Orobanche, Salvia, Stellera inherited by family Menyanthaceae: fused with a corolla (calyx in Thymelaeaceae)
|
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 Menyanthaceae: 1
|
Carpel number: (i)Number of carpels (carpel: forming a simple pistil or part of a compound pistil, modified leaf). | 2 inherited by family Menyanthaceae: 2
|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Menyanthaceae: 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 Menyanthaceae: 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 Menyanthaceae: bisexual, hermaphrodite
|
Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis | |
Appearance: (i)Outer look of the inflorescence. | terminal (i)Inflorescence is the highest point of the plant and may consist of a single flower only example: Cypripedium, Rhaponticum, Ligularia sibirica, Echinops inherited by family Menyanthaceae: 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. | dry (i)With a dry outer shell, no fleshy parts, but seed (embryo) could be edible inherited by family Menyanthaceae: dry
|
Type of fruit: (i)Common fruit types (including pseudocarp). | Solitary fruits (i) inherited by family Menyanthaceae: 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 family Menyanthaceae: capsule Dehiscent fruits (i)Fruits open along a longitudinale line (except silicula) inherited by family Menyanthaceae: Dehiscent fruits
|
Hairs | |
Has hairs?: | no hairs, glabrous inherited by family Menyanthaceae: no hairs, glabrous
|
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 Asterales: allorhizous
