Habitat:Preferably on debris covered slopes (acc. to H. Freitag und M. Maier-Stolte)
Habit (i)general appearance of a plant
Growth form: (i)Herb, shrub, tree or climber.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 Ephedra: shrub, subshrub or semishrub
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 vasc. plants: no parasite/saprophyte
Water or terrestrial plant: (i)Where do the plants grow?terrestrial (i)Plant grows on dry land
example: Orostachys spinosa
inherited by vasc. plants: terrestrial
Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)
Leaf development: (i)Structure and development of leaves.with green leaves (i)Plant with green leaves inherited by vasc. plants: with green leaves
without green leaves (i)Plant at flowering time (some geophytes) or over its whole life (many parasites) with reduced leaves without chlorophyll
example: Colchicum, Cuscuta, a lot of parasites
inherited by family Ephedraceae: without green leaves
needles or scales (i)Leaves short, broad more or less adjacent to axis (scales)) or acicular (needles)
example: Pinus (needles), Cupressus, Ephedra (scales)
inherited by vasc. plants: needles or scales
Leaf arrangement: (i)Arrangement of leaves at the stem.opposite, opposite-decussate (i)Two leaves per node
example: Lamiaceae, e.g. Phlomis
inherited by family Ephedraceae: opposite, opposite-decussate
Flower (i)reproductive portion of the plant, consisting of sepals, petals, stamens, and pistils
Perianth arrangement: (i)Attention: in some plants, flowers may be dimorphic in different ways (dioecious or gynodioecious). If flowers vary, record the characters of the most showy flowers.absent or strongly reduced (i)No perianth leaves ensheathing stamen and/or carpels
example: Callitriche
inherited by vasc. plants: absent or strongly reduced
Ovary position: (i)For entirely or partly fused carpels, describe their position in relation to the insertion point of perianth leaves (best done by doing a longitudinal section of a flower).absent (i)Without ovary: male flowers inherited by order Gnetales: absent
Sex: (i)Distribution of male and female organs among flowers, only most commonly cases.unisexual (i)
example: Rhodiola
inherited by vasc. plants: unisexual inherited by genus Ephedra: unisexual
dioecious (i)Male and female flowers at different individuals
example: Antennaria
inherited by genus Ephedra: dioecious
Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis
Inflorescence type: (i)Types of inflorescence. Attention: We here ask for the botanical nomenclature of inflorescences, which is sufficiently complicated. Tick only, if you are certain, or tick all inflorescence types that appear similar of these of the plant in question.Cone (i)Flowers densely arranged along a short, often thickened axis, looking towards all sides
example: Pinus, Ephedra
inherited by vasc. plants: Cone
Fruit (i)the seed bearing organ, with or without adnate parts; a ripened ovary and any other structures which are attached and ripen with it. Aggregate fruits are handled like simple fruits for determination.
Type of fruit: (i)Common fruit types (including pseudocarp).cone (i)No fruit, but often considered as fruit
example: Pinaceae, Cupressaceae, Ephedraceae
inherited by vasc. plants: cone
Pseudofruit (i)Special types of diaspores, often no real fruits inherited by vasc. plants: Pseudofruit
Distribution (i)region where the plant is likely to be found
Distribution (Veg. Zones): (i)acc. to Grubov 1952Mongolian Altai (i)In distribution data often named as '7'
Dzungarian Gobi (i)In distribution data often named as '14'
Transaltai Gobi (i)In distribution data often named as '15'
