| 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
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
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 
|
| Smell & Touch: (i)General appearance of the plant. | odor (i)Plant with an obvious scent
|
| 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
from 250 mm to 600 mm
from 600 mm to 1000 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 Lamiaceae: no parasite/saprophyte
|

example: Orostachys spinosa inherited by family Lamiaceae: terrestrial
|
| Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades) | |
| Leaf development: (i)Structure and development of leaves. | flattened blade (i)Cross-section of lamina flat, plain inherited by family Lamiaceae: flattened blade

|
| 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 Leonurus: compound
palmate (transition to palmatisected!) (i)Divided from a point, like the fingers of a hand
example: Cannabis, Hibiscus (3-5 parts)  inherited by genus Leonurus: palmate (transition to palmatisected!)
|
| Shape of blade: (i)Easy for simple leaves. In compound leaves use the general shape of leaflet. Always check the ground for largest leaves of a plant.
