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 Iridaceae: simple
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. To be worked out: how to handle pinnate leaves?linear incl.grasslike or oblong (i)Leaves more than two times longer than broad with more or less parallel margins; see character: stipule for ligula

Leaf margin: (i)Structure of leaf margin (or that of a leaflet in case of compound leaves).

example: Incarvillea, Cypripedium

Flower symmetry: (i)Symmetry of the perianth leaves. Attention: to assess this character, look on sepals, petals and stamens, but neglect carpels and ovary.radiary, regular (actinomorphic) (i)More than two axis of symmetry
example: Saxifraga: 5; Iris: 3
