| Habitat: | Desertified stony and debris slopes, rocks, screes, sandy-pebble bottom of sayrs (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 family Boraginaceae: herb
|
| Parasite status: (i)Is the plant a half- or full parasite? | no parasite/saprophyte (i)Plant fully autonomous, leaves with chlorophyll

|
| Water or terrestrial plant: (i)Where do the plants grow? | terrestrial (i)Plant grows on dry land

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

example: Polemonium inherited by family Boraginaceae: 5
|
| Sepal fusion: (i)To which degree are the sepal leaves connected? Attention, this character applies only for flowers separated in sepals and petals, thus excluding most monocots. Be aware of the bracts (involucral leaves) of Asteraceae flowerheads, do not qualify these as sepals! | fused (i)Leaves united, only tips are free
example: Fabaceae, Silene   inherited by family Boraginaceae: fused
|
| Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured). | 5 (i)
