| 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 Melanthiaceae: herb
perennial (i)Living for several to many years, as opposed to annual and biennial inherited by family Melanthiaceae: 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 Melanthiaceae: no parasite/saprophyte
|
| Water or terrestrial plant: (i)Where do the plants grow? | terrestrial (i)Plant grows on dry land

basal rosette (i)Leaves positioned at the base of the stem; stem often without leaves, no visible internodes (but flowers often on erect stems, and these may have few leaves)
example: Limonium, Potentilla, Plantago; also used in Liliales with basaly crouwded leaves (Tofieldia, Zigadenus etc.) 
|
| 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 Melanthiaceae: 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? | lanceolate (i)Lance-shaped; much longer than wide, with the widest point in the middle or below

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