|
| 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 Primulaceae: with green leaves
|

|
| 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 Primulaceae: 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 Lysimachia: 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 Primulaceae: radiary, regular (actinomorphic)
|
| Flower form: (i)common forms of flowers ? Veronica | 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 Lysimachia: tubular to funnel-shaped
campanulate (i)Petals united to a bell-shaped corolla  inherited by genus Lysimachia: 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 genus Lysimachia: 5
|
| Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i)
example: Potentilla inherited by genus Lysimachia: 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 Primulaceae: 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 Primulaceae: 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 genus Lysimachia: 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 Primulaceae: 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 Primulaceae: 1
|
| Carpel number: (i)Number of carpels (carpel: forming a simple pistil or part of a compound pistil, modified leaf). | 5 inherited by family Primulaceae: 5
|
| 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 Primulaceae: fused
|
| Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1 inherited by family Primulaceae: 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 Primulaceae: 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 Primulaceae: 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. | |
| 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 Primulaceae: dry
|
| Type of fruit: (i)Common fruit types (including pseudocarp). | Solitary fruits (i)    inherited by family Primulaceae: 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 Primulaceae: capsule
Dehiscent fruits (i)Fruits open along a longitudinale line (except silicula) inherited by family Primulaceae: Dehiscent fruits
|
| Opening of fruit: (i)Mode of dehiscence at maturity to release seeds. | opening / dehiscent (i)Dry? Fruits opening with different types inherited by family Primulaceae: opening / dehiscent
|
| 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 Ericales: allorhizous
|
| Distribution (i)region where the plant is likely to be found | |

Khangai (i)In distribution data often named as '3'
