Description: | Dioecious twinning liana, dying by winter. Leaves alternate, peltate acute-5-partite or 5-lobate, broad emarginate at base and acute at apex. Flowers in short axillary panicles, about 6 mm in diam., with 4-8 sepals and 12 petals. Fruit a globose juicy, aggregate drupe about 8 mm in diam. |

Habitat: | Stony slopes, rocks, screes, river and stream banks (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 perennial (i)Living for several to many years, as opposed to annual and biennial
|
Special growth forms or habits: | climber or liana (i)Plant with twinging stems example: Clematis, Menispermum inherited by genus Menispermum: climber or liana
|
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 Menispermaceae: 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 family Menispermaceae: terrestrial
|

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
|
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? | cordate (i)Heart shaped example: Cortusa peltate (i)Leaf with with petiole attached to the lower surface of the blade example: Menispermum dauricum
|
Length of leaves: (i)How long is the leaf, be carefull in compound leaves, measure the complete leaf. | from 21 mm to 50 mm more than 50 mm

|
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.

If flowers vary, record the characters of the most showy flowers. | double, different (i)Two types of perianth leaves, differently coloured (sepals: outer periant leaves, usually greenish, and petals: inner perianth leaves, usually coloured) example: Parnassia
|
Diameter of flower: (i)Diameter of flower or flower head. | from 5 mm to 10 mm (i) example: Stellaria
