| Habitat: | Forest fringes and open coniferous and mixed forests, shrubberies, river banks, stony slopes and bottom of creek valleys (Grubov 2001). |
| 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 genus Spiraea: herb
perennial (i)Living for several to many years, as opposed to annual and biennial inherited by genus Spiraea: 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 Spiraea: shrub, subshrub or semishrub

|
| 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 genus Spiraea: 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? | elliptic (including ovate and obovate) (i)Elliptic: broadest at the middle and narrower at the two equal ends; ovate: egg-shaped, attached at the broad end; obovate: attached at the narrower end
example: Limosella aquatica  inherited by genus Spiraea: elliptic (including ovate and obovate)
lanceolate (i)Lance-shaped; much longer than wide, with the widest point in the middle or below  inherited by genus Spiraea: lanceolate
|
| Leaf margin: (i)Structure of leaf margin (or that of a leaflet in case of compound leaves).

To be worked out: how to handle margin of pinnate leaves? | serrate / dentate / crenulate (i)Margin saw-like or rounded teethed
example: Betula, Lophanthus (crenulate)  inherited by genus Spiraea: serrate / dentate / crenulate
