Dracunculus), and Chenopodiaceae
were dominating, with a smaller proportion of Ephedra, Lycopodium dubium, Diphazium alpinum, and Selaginella selaginoides.
shrubby elements of the Chenopodiaceae
, Ephedraceae, and Convolvulaceae
In sample 1 of core I, the presence of Chenopodiaceae
and other dry autochthonous elements like Ephedra indicate the proximity of sand dunes or levee banks (Leroy 1992).
Other pollen taxa include Poaceae which averages 6%, Asteraceae 3%, Chenopodiaceae
2%, and Cyperaceae 1%.

most successful invaders belong to the Papaveraceae, Chenopodiaceae
Sample 3/8532a produced a moderate but countable pollen concentration (16,158 gr/ml) dominated by Poaceae (grasses), Cyperaceae (sedges), Lactuceae (Dandelion family), Plantago lanceolata (Ribwort Plantain), Pteridium (Bracken) and a few grains of other herbs including Adonis type (Pheasants Eye), Anthemis type (Chamomile), Galium type (Bedstraw), Rumex acetosella (Sheeps Sorrel), Centaurea nigra (Black Knapweed) and Chenopodiaceae
(Goosefoot family) (TABLE 1).
Nine families, Fabaceae (32), Asteraceae (16), Verbenaceae (11), Euphorbiaceae (10), Boraginaceae (seven), Chenopodiaceae
(seven), Malvaceae (seven), Rutaceae (five), and Solanaceae (five) account for 56.
Only a few families, such as Cyperaceae, Brassicaceae, Caryophyllaceae, Juncaceae, Chenopodiaceae
and Amaranthaceae, are assumed never to form mycorrhizal associations or to do so rarely .
Quite frequently traces of fires are accompanied by pollen of Pediastrum, Artemisia, Plantago major, Chenopodiaceae
, as well as high percentages of Pteridium aquilinum, Betula, Populus, and Urtica.
95 intervals on all percentage values of Pinus, Carya, Ulmus, Franseria, and Chenopodiaceae
are overlapping (Fig.

The vegetation on the grey soils of the lake floor comprises a eucalypt woodland (Coolabah and Blackbox) interspersed with Acacia stenophylla and Chenopodiaceae
with lignum in the areas where semi-permanent swamps are found.
Among the anemophilous species, some have most of the typical features, not surprisingly among the Chenopodiaceae
, Cyperaceae, Juncaceae, Poaceae, Urticaceae, and the genera Coprosma, Dysopsis, Empetrum, Gunnera, Haloragis, Peperomia, Plantago, and Lactoris (Bernardello et al.
Several families in this order have genera of wetland plants, such as the Aizoaceae (Sesuvium), Polygonaceae (Rumex, Polygonum, Brunnichia), Chenopodiaceae
(Halimione, Chenopodium, Atriplex, Salicornia, Suaeda), Amaranthaceae (Amaranthus, Acnida), and Portulacaceae (Montia).
