26. Atriplex patula glabriuscula (Edmonston). — Plant with widely spreading de- 

 cumbent or prostrate branches forming circular patches; leaves rather small (blades of 

 the lower ones 1.5 to 3 cm. long, 1 to 2 cm. wide), petioled; blade triangular with short 

 lobes or only subhastately angled at base (the upper leaves lanceolate), dentate or 

 sometimes entire; glomerules in the axils of the upper leaves; fruiting bracts ovate or 

 triangular, 6 to 12 mm. long, broad at base, the margins sinuate or low-dentate, the 

 face with small clusters of tubercles or smooth (fig. 30, a to d). {A. glabriuscula Ed- 

 monston, Fl. Shetland 39, 1845.) Sea-shores from Newfoundland to Maine and very 

 locally to Rhode Island and casual on the ballast southward ; also in Iceland, the British 

 Isles, and continental Europe. The distribution given for America is quoted from 

 Fernald (Rhodora 23:262, 1921), who cites a long series of collections.' Only two col- 

 lections have been examined by the present writers, namely : Charnay , Labrador Penin- 

 sula, Quebec, St. John 90408 (Gr); Sandy Beach, Miscou, Gloucester County, New 

 Brunswick, Blake 5564 (Gr). 



2c. Atriplex patula typica. — Plant usually erect, the branches either ascending or 

 widely spreading, strict and with few short branches in dwarf forms; leaves medium-sized, 

 petioled ; blade lanceolate or oblong, rounded or narrowed to the base, not hastate, entire 

 or denticulate or rarely with a pair of basal lobes pointing forward; glomerules scattered 

 along the spike-like branches of a terminal panicle or the whole inflorescence spike-like 

 in reduced forms; fruiting bracts rhomboid or roundish, 3 to 6 mm. long or up to 8 mm. . 

 in plants of good soil, narrowed to the base, the margins sparsely denticulate, but the teeth 

 sometimes very obscure, rarely entire, the face commonly smooth. {A. patula Linnaeus, 

 Sp. PI. 1053, 1753.) Newfoundland to the Gulf of Mexico, southern California, and 

 British Columbia; common throughout the United States and southern Canada in a 

 great variety of forms, also in Europe and Asia. Type locality, Europe. Collections: 



* In the paper above referred to, Fernald records A. patula var. bracleata Westerlund, Sveriges Atripl. 57, 1861, as 

 occurring in North America. The record is based upon a single specimen collected near the mouth of George River, Cape 

 Breton. In this form the bracts are as long as or even longer than those of glabritiacula, but the inflorescence is not leafy- 

 bracted. In many respects it is close to subspecies obtusa.
