Anabasis cretacea (Anabasis cretacea)
Description
The species of genus Anabasis are annual or perennial herbs or subshrubs. Their stems are fleshy and articulated, mostly glabrous with the exception of hairy tufts at the nodes, rarely with papillae-like trichomes or woolly. The opposite leaves may be reduced to small scales or normally developed. The inflorescences are elongated or condensed spikes. The bisexual flowers are sitting solitary or in groups of up to 4 in the axils of upper leaves (bracts), with 2 paired bracteoles. Flowers consist of 5 subequal membranous perianth segments, that are free nearly from base; 3-5 stamens without appendages; and an ovary with 2-3 thick and short stigmas. In fruit, prominent membranous wings develop on the back of the perianth segments, usually 2-3 of them larger than the others. Rarely, the perianth remains unwinged. The fruit may be baccate or dry, either vertical and compressed or nearly spherically shaped. The lenticular seed is vertically orientated, filled by the spiral embryo without endosperm.
