I have seen no plant conforming to the above description, ivhich is taken from Moqnin’s, in De Candolle’s
‘ Prodromus,’ where it is further described as an erect, rather rigid herb, with leaves, including the petiole, 2-2-|-
inches long. The large leaves, subcordate at the base, not farinose below, and opaque, rugose seed, ivill distinguish
this from C. glaucum.

• A considerable number o f species o f Atrip lex are fouud on the temperate coasts of Australia, and in the desert
interior; about seventeen are knoivn, of wliich the majority inhabit tbe south-western quai-ter. Though many of
these are certainly peculiar, some will no doubt prove to be varieties of widely diffused plants ; most o f them are
shrubby, and densely clothed witb white, farinaceous scales.— Herbs or sbinibs, often saline, witb alternate leaves,
and minute fiowers aggregated iuto spicate glomerules. Floicers unisexual. Males bractless, witb a three- to five-
partite perianth, and as many stamina, and a mclimentaiy pistil. Females with or without a perianth, bibraeteate,
the bracts enlarging and enclosing the fruit; ivithout stamens. Oaary small, with two styles. Utriculus rnQm-
brauaceous, with one horizontal seed. (Name from a, privative, and rpetfiav, to nourish ; in contradistinction to
Chenopodium, ivhich contains several pot-herbs.)
