| Scientific name: | Chamaerhodos erecta (L.) Bunge |
| Name acc. to: | Gubanov 1996 |
| Herbar: | list records    |
| Description: | Biennial, 5-60 cm tall, with radical leaf rosette. Radical leaves 2-3 pinnatipartite, segments narrow-linear. Stem usually solitary, but sometimes several (modified by grazing?), straight, leaved; rosette usually drying up by fruiting time. Sepals long-cuspidate. Petals pale pink or white, emarginate at tip, petals 2.5-4 mm long. Nutlets dull. |
| Confuse with: | C. sabulosa, especially small, rather ascending plants. |
| Tax. Comments: | Main differences to C. sabulosa are the narrow-linear leaf segments and the long-cuspidate sepals. |

| 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

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)

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.
