species: 2
Habit (i)general appearance of a plant
Growth form: (i)Herb, shrub, tree or climber.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 Peganaceae: herb
perennial (i)Living for several to many years, as opposed to annual and biennial inherited by family Peganaceae: perennial
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 Peganaceae: 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.simple (i)Non-divided leaf, but margin may be incised nearly to the ground inherited by family Peganaceae: simple
palmatisected, but simple leaf (i)Leaf more than 1/3 of leaf lamina divied into more than three parts; there is a gradual transition from deeply divided leaves to palmate ones
example: Trifolium lupinaster
inherited by family Peganaceae: palmatisected, but simple leaf

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.5 (i)
example: Polemonium
inherited by family Peganaceae: 5
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured).5 (i)
example: Potentilla

example: Peganum
inherited by family Peganaceae: no spur
Stamen number: (i)Attention: We ask for the reproductive organs of the flower dispersing pollen. Count only fully fertile stamens, not staminodia (e.g. Parnassia).> 10 (i)
example: Nymphaea, Callianthemum, Rosa
