Habitat: | Sandy steppes, stony and debris steppe slopes, rocks, dry river beds, sandy-pebble and alkaline river banks (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 Hypecoum: annual 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 Hypecoaceae: herb inherited by genus Hypecoum: herb
|
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 inherited by genus Hypecoum: from 250 mm to 600 mm inherited by genus Hypecoum:
|
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 Hypecoaceae: 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 Hypecoaceae: 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 Hypecoum: with green leaves
|
Leaf arrangement: (i)Arrangement of leaves at the stem. | basal rosette (i)Leaves positioned at the base of the stem; stem often without leaves, no visible internodes (but flowers often on erect stems, and these may have few leaves) example: Limonium, Potentilla, Plantago; also used in Liliales with basaly crouwded leaves (Tofieldia, Zigadenus etc.) inherited by genus Hypecoum: basal rosette
|
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. | compound (i)Composed of several similar parts inherited by genus Hypecoum: compound pinnate (i)With leaflets on both sides of an axis, at least 2 pairs or more example: Onobrychis inherited by genus Hypecoum: pinnate
|
Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk) inherited by genus Hypecoum: with
|
Leaf colour upper side: (i)Shades of green on the leaf, upper side. | green (i)Clear green example: Tribulus terrestris inherited by genus Hypecoum: green

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 Hypecoum: 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. | 2 (i) example: Papaveraceae inherited by genus Hypecoum: 2
