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

example: Artemisia pectinata
inherited by genus Chamaerhodos: herb
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:

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.
