Delt Sea Orrach. Petiv. H. Brit. t. 7.f. 2. 



In cultivated as well as waste ground, and on dunghills, common. 



/3 and y. By the sea side, or in salt marshes. 



Annual. June — August. 



Root fibrous, certainly annual in all the varieties, more slender 

 than in yi. laciniata. Stem most commonly erect, with long, 

 spreading branches ; the herbage of a dull green, slightly mealy; 

 but in j3 and y the whole plant is procumbent, more glaucous, 

 often reddish, and somewhat fleshy. Leaves alternate, on long 

 stalks, most powdery at the back ; the lower ones halberd- 

 .shaped, having two large, acute, spreading lobes at the base, 

 with many very unequal, sharp, scattered teeth, between them 

 and the point; the base quite entire; upper ones gradually 

 narrower, with smaller lobes or none at all, so that the floral 

 ones are perfectly lanceolate, as well as entire. Spikes termi- 

 nal and axillary, long, erect, interrupted, the ^o?(;ers in little 

 round dense tufts. The bivalve calyx of the fertile ones is armed 

 at both sides with several prominent acute tubercles, or prickles. 

 In these alone seed is produced, which is finely dotted, twice as 

 large as that of the following species. 



Linngeus misled our Jiritish botanists by referring Morison's sy- 

 nonym of this plant to his A. hastata; whereas his own herba- 

 rium and definitions prove it to be his patula ; the real hastata, 

 not known in Britain, differing widely, in the large, reticulated, 

 sinuated valves of the fruit-bearing calyx, whose long teeth ter- 

 minate in bristly points. 



Our /3 is declared by Doody, in Raii Sijn. eel. 2. 341, to be annual, 

 not perennial, and therefore, perhaps, is hardly to be known 

 at all from the common sort. I have never met with any thing 

 answerable to this, y often occurs on sandy ground by the sea. 

 It is prostrate, more glaucous and fleshy, with a frequent tinge 

 of red, and smaller, less toothed, or quite entire, leaves, differing 

 from its natural inland habit, as many other plants, in maritime 

 situations, often do. 



4. A. angustifolia. Spreading Narrow-leaved Orache. 



Stem herbaceous, spreading. Leaves lanceolate, entire; 

 tlie lower ones partly three-lobed. Calyx of the fruit 

 halberd-shaped, slightly warty at the sides.
