|Name acc. to:||APG III|
|Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)|
|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 |
|Leaf margin: (i)Structure of leaf margin (or that of a leaflet in case of compound leaves). Attention: Here we ask for the leaf margin, defined as all those dissections that separate the leaf for less than one third of its length or width, whatever is smaller. To be worked out: how to handle margin of pinnate leaves?||entire (i)Plain margin, not toothed|
|Leaf veination: (i)Arrangement of the main veins of a leaf.||parallel (i)Most veins arranged parallel to the length of leaf, mostly no pronounced main vein (usually in elongate to linear leaves)|
example: Most Monocotyledonae, Plantago, Veratrum, a lot of Caryophyllaceae looks like that.
|Root / shoot below ground (i)plant part below ground (in most cases), including below ground shoots, without leaves|
|Root type: (i)Organisation of the roots.||homorhizous (i)Many equal roots|
