Class:angiosperms
Order:Alismatales
Family:Zannichelliaceae
Genus:Zannichellia
Scientific name: Zannichellia palustris L.
Name acc. to:Gubanov 1996, not in Grubov 1982/2001
Herbar:list records    scans available    photo available    habitat photo available    
Synonym: Z. pedunculata auct. Mong. (acc. to Grubov (1982))
Description:Stem filiform, intensely branched. Leaves narrow-linear 1.5-3.5 mm long. Fruits including pedicel 3-4 mm long, style shorter than fruit.
Tax. Comments:All specimens examined have fruits about 3(4) mm long including 1-1.5 mm long style. The length is measured including pedicel. The style is mostly at least half as long as the seed bearing fruit part. Therefore all have been determined as Z. palustris s.l. Further studies are necessary to clear the taxonomic situation.

Habitat:In rivers, dirches, lakes (Flora of Siberia, Vol. 1, 2000).
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 Zannichelliaceae: herb
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 Zannichelliaceae: no parasite/saprophyte
Water or terrestrial plant: (i)Where do the plants grow?water or swamp plant inherited by family Zannichelliaceae: water or swamp plant
aquatic, submerged (i)Completely submerged water plant, onlys flowers may appear at the surface
example: Zannichellia
inherited by family Zannichelliaceae: aquatic, submerged
Leaf (i)expanded, usually photosynthetic organ of a plant (including phylloclades)
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?filiform (i)Leaves thread-like, at least more than ten times longer than broad
example: Potamogeton pectinatus, P. filiformis
inherited by family Zannichelliaceae: filiform
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
example: Iris
inherited by family Zannichelliaceae: entire
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.
inherited by family Zannichelliaceae: parallel
Flower (i)reproductive portion of the plant, consisting of sepals, petals, stamens, and pistils
Flower appearance and pollination: (i)General appearance of the flower.not attractive, wind-pollinated or some water plants (i)Small, colourless or green flowers
example: Betula, grasslike plants: Carex, Setaria, Juncus
inherited by family Zannichelliaceae: not attractive, wind-pollinated or some water plants
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 family Zannichelliaceae: absent or strongly reduced
simple, similar (i)Only one type of perianth leaves (tepals)
example: Tulipa
inherited by family Zannichelliaceae: simple, similar
Diameter of flower: (i)Diameter of flower or flower head. from 5 mm to 10 mm (i)
example: Stellaria
inherited by family Zannichelliaceae:
Petal / Tepal number: (i)Number of petal leaves (inner perianth leaves, usually coloured).none or reduced (i)But green sepals may exist
example: Thalictrum
inherited by family Zannichelliaceae: none or reduced
Spur: (i)A hollow, slender, sac-like appendage of the perianth leaves, storing nectar.no spur (i)Flower without appendage
example: Peganum
inherited by family Zannichelliaceae: no spur
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).superior (hypogynous) (i)Base of carpels attached above insertion point of perianth leaves, carpels free or fused
example: Delphinium, Anemone
inherited by family Zannichelliaceae: superior (hypogynous)
Inflorescence (i)flowering part of a plant, describes the arrangement of the flowers on the flowering axis
Inflorescence: (i)Structure of the inflorescence.Solitary flowers (i)Each flower grows on an own leafy stem there may be more than one, if the plant has many leafy shoots
example: Viola, Saxifraga hirculus, Rubus arcticus
inherited by family Zannichelliaceae: Solitary flowers
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
example: Monocotyledonae
inherited by order Alismatales: homorhizous
Distribution (i)region where the plant is likely to be found
Distribution (Veg. Zones): (i)acc. to Grubov 1952Mongol-Daurian (i)In distribution data often named as '4'
acc. to: Gubanov 1996
