Habitat: | debris deserts, tailings of mountains and hills, stony slopes and rocks, red clays and sandstones, alkaline banks of springs, chee-grass stands (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 perennial (i)Living for several to many years, as opposed to annual and biennial
|
Size of plant: (i)Attention: use flowering or fruiting specimens to assess plant height (many biennial plants possess only a basal rosette in the first year). | from 100 mm to 250 mm
|
Parasite status: (i)Is the plant a half- or full parasite? | no parasite/saprophyte (i)Plant fully autonomous, leaves with chlorophyll example: Most plants, Ranunculus inherited by family Zygophyllaceae: no parasite/saprophyte
|
Water or terrestrial plant: (i)Where do the plants grow? | terrestrial (i)Plant grows on dry land example: Orostachys spinosa inherited by family Zygophyllaceae: terrestrial inherited by genus Zygophyllum: terrestrial
|
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 genus Zygophyllum: with green leaves fleshy leaf (i)Leaves more or less thick, juicy, terete or flat example: Crassulaceae inherited by genus Zygophyllum: fleshy leaf
|
Leaf arrangement: (i)Arrangement of leaves at the stem. | opposite, opposite-decussate (i)Two leaves per node example: Lamiaceae, e.g. Phlomis inherited by genus Zygophyllum: 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. | paripinnate / evenpinnate (i)A pinnate leaf with all leaflets in pairs inherited by genus Zygophyllum: paripinnate / evenpinnate compound (i)Composed of several similar parts inherited by genus Zygophyllum: compound pinnate (i)With leaflets on both sides of an axis, at least 2 pairs or more example: Onobrychis inherited by genus Zygophyllum: pinnate
|
Leaf margin: (i)Structure of leaf margin (or that of a leaflet in case of compound leaves). Attention: Here we ask for the leaf margin, defined as all those dissections that separate the leaf for less than one third of its length or width, whatever is smaller. To be worked out: how to handle margin of pinnate leaves? | entire (i)Plain margin, not toothed example: Iris inherited by genus Zygophyllum: entire
|
Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk) inherited by genus Zygophyllum: with

|
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 Zygophyllum: double, different
|
Diameter of flower: (i)Diameter of flower or flower head. | from 10 mm to 20 mm (i) example: Potentilla
|
Flower symmetry: (i)Symmetry of the perianth leaves.

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 genus Zygophyllum: 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
|
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
|
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i) example: Potentilla
|
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 genus Zygophyllum: 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 Zygophyllaceae: no spur

|
Style number: (i)Portion of the pistil connecting the stigma to the ovary. | 1
|
Stigma number per style: (i)Number of stigmas per style. | 1 (i)One stigma, sessile or with a developed style
|
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 genus Zygophyllum: superior (hypogynous)
