example: Artemisia pectinata   inherited by family Salicaceae: herb
perennial (i)Living for several to many years, as opposed to annual and biennial inherited by family Salicaceae: perennial
shrub, subshrub or semishrub (i)Shrub, multi-stemmed, mostly (0.2) 0.5 - 5 m high, shoots woody up to the tip

| 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 Salicaceae: simple
|
| Petiole: (i)Leaf divided into stalk (petiole) and blade. | with (i)Leaves with petiole (stalk)  inherited by family Salicaceae: with

example: Malus inherited by family Salicaceae: free
fused with each other (i)All or most stamens fused with each other to a tube-like structure
example: Caragana, Petasites inherited by genus Salix: fused with each other
|
| Pistil number: (i)Number of pistils (female floral organs: style, if developed; stigma and carpels/ovary together build the pistil). | 1 (i)One carpel, but clearly one stigma
example: Pyrola, Primula, Alyssum inherited by family Salicaceae: 1
|
| Carpel fusion: (i)To which degree are the carpels (modified leaf forming simple pistil or part of a compound pistil) fused. | fused (i)Carpels united into an ovary, only styles are free
