| Habitat: | Debris and stony steppe slopes of mountains, sandy steppes, montane steppes, rocks (Grubov 2001). |
| Habit (i)general appearance of a plant | |
| Growth form: (i)Herb, shrub, tree or climber. | 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 Chamaerhodos: 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

perennial (i)Living for several to many years, as opposed to annual and biennial inherited by genus Chamaerhodos: perennial
shrub, subshrub or semishrub (i)Shrub, multi-stemmed, mostly (0.2) 0.5 - 5 m high, shoots woody up to the tip
example: Caragana leucophloea  inherited by genus Chamaerhodos: shrub, subshrub or semishrub
|
| 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). | to 100 mm inherited by genus Chamaerhodos:
from 100 mm to 250 mm inherited by genus Chamaerhodos:
from 250 mm to 600 mm inherited by genus Chamaerhodos:
|
| 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 Rosaceae: no parasite/saprophyte
|
| Water or terrestrial plant: (i)Where do the plants grow? | terrestrial (i)Plant grows on dry land

| 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. | trifoliate (i)Three-parted leaf (often called ternate)

| 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.

example: Polemonium inherited by genus Chamaerhodos: 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.
