places by flic sen. rommoii, and apparently generally distributed. 

 In Scotland it is much the most common coast Atriplex. 



England, Scotland, Ireland. Annual. Late Summer, Autumn. 



A very variable plant, at times a[)proachin,a' closely in habit to the 

 maritime forms of A. hastata, at others resembling rather A. arenaria, 

 with which it has often been confounded. Stems 3 inches to 2 feet 

 long or more, the smaller forms usually more densely clothed ^vith 

 white meal than the larger. Largest leaves f to 3 inches long, 

 usually distinctly hastate, sometimes sinuate-serrate, at other times 

 nearly entire. Spikes simple or more rarely somewhat panicled, 

 usually leafy nearly to the apex, with the glomerules so far apart 

 that they might be described as axillary clusters. Fruit perianth 

 ^ to ^ inch long, differing from that of A. hastata in being wedge- 

 shaped at the base, more indurated, and generally turning blackish 

 when ripe, and also in the basal margins being imited as far up as the 

 lateral angles, which are about half-way up the valves. Seeds about 

 as large as rape seed, finely shagreened. Plant generally much whiter 

 and less shining than A. hastata, especially when growmg on a sandy 

 coast ; but the larger forms, growing on shingle, or in waste places 

 by the sea, are sometimes quite as green, or even greener, than mari- 

 time forms of A. hastata, of which it may be but a subspecies.

Annual. Stem herbaceous, wiry, ascending, much branched ; 

 branches ascending and curving upwards. Lowest leaves mostly 

 opposite, rhombic-roundish or quadrate-rhombic, wedgeshaped at the 

 base, not hastate, dentate or sinuate-dentate ; middle and upper leaves 

 rhombic or rhombic-oblong, often subhastate with the ascending cusps ; 

 otherwise generally entire. Flowers monoecious, in glomerules col- 

 lected mto short spikes at the apex of the stem and branches ; the 

 terminal glomerules almost contiguous, nearly leafless, and consisting 

 of male flowers only; the lower ones rather remote, and with leaves 

 at the base, consisting of several male, and from 2 to 7 female flowers 

 Fruit perianth transversely rhombic or quadrate-rhombic ; the valvei 

 united up to the lateral angles, wedgeshaped at the base, toothe
