Common on wet marshes along the coast from Anticosti to Connecti- 
cut, and occasionally southward to Louisiana. Eurasia. 
Walter's specimen of his Chenopodium maritimum from the Caro- 
lina coast is not readily distinguished from this, though his descrip- 
tion is cited by Elliott under Salsola linearis. On the Massachusetts 
coast and southward the ascending bushy form of the plant prevails, 
but from Ipswich northward along the coast of Maine and Eastern 
Canada it often gives way to a more depressed and usually more 
glaucous plant, which, however, cannot be clearly separated from the 
other form. Apparently the same forms in the British Isles have a 
distribution parallel with this, for, according to Syme “the erect 
variety is more common in the south, the procumbent in the north; 
but it is scarcely possible to draw any line of demarcation between 
them" (Engl. Bot. ed. 3, viii. 4.). 
* * Seed 1.25 to 1.5 mm. broad. 
4— Sepals rounded on the back, not carinate. 
S. Richii. Stems procumbent, forming mats 5 dm. or less across 
(often fruiting when only 1 cm. or so long): leaves dark green, not at 
all glaucous, linear to linear-oblong, bluntish, subcylindric, dorsally 
compressed, the lower 1.5 cm. or less in length; those subtending the 
fascicles of flowers broader and shorter (4 or 5 mm. long): seed black. 
— Common on salt marshes and in damp spots at the edge of the beach, 
Wells, Maine, Aug., 1892 (Anne E. Perkins), Sept. 16, 1895 (Walter 
Deane), July 23, 1898, TYPE (J. C. Parlin & M. L. Fernald), Sept. 
1898 (Kate Furbish); also on Great Cranberry Isle, Maine, Aug. 30, 
1892 (E. L. Rand), and at Cutler, Maine, Aug. 27, 1902 (M. L. Fernald). 
A very distinct species, in its procumbent habit suggesting the depressed 
form of S. maritima, but, in the field, quickly distinguished by its 
short blunt dark (not glaucous) green foliage, as well as its small 
seed. From the other small-seeded species, S. linearis, it is distin- 
guished by its procumbent habit and short blunt leaves, as well as by 
the rounded (not carinate) sepals. Unlike any other American plant, | 
this Suaeda in habit strongly suggests S. microsperma (C. A. Meyer) 
Fenzl, but that Asiatic plant has much smaller seeds, and the sepals 
cucullate-carinate. 
This procumbent small-seeded plant of the Maine coast is named 
for William Penn Rich, a discriminating student of salt marsh vege- 
tation, who in April, 1898, pointed out in the herbarium of Mr. Walter 
Deane the peculiarities of the species here described.
