Reports of explorations and surveys, to ascertain the most practicable and economical route for a railroad from the Mississippi River to the Pacific Ocean: Vol. 4, Pt. 3

OBIONE POLYcARPA, Torr. (in Emory's 1st Report, p. 149, sine char.): suffruticosa, ramosissima;
ramulis gracilibus paniculatis; foliis raintis sessilibus obovato-oblongis obtusis integerrimis
albido-farinosis; bracteis orbicularibus, supra mediam distinctis argute grosse-deutatis, utrinque
cristatis. With the preceding. Leaves 3-5 lines long, crowded. Fruit abundant, aggregated
on the long slender branchlets. Fructiferous bracts about 2 lines in diameter.
OBIONE CANEScENS, Moq. 1. c. p. 212. Llano Estacado; September; fruit. The specimens
belong to the form with broadly winged fruit-bracts.
OBIONE ARGENTEA, Moq. 1. c. p. [115. Atriplex argentea, Nutt. Gen. 1, p. 198. Upper
waters of the Canadian; with ripe fruit, in which state it is seldom collected. The fructiferous
bracts are somewhat orbicular, the margin deeply and acutely toothed, and the disk is often
more or less cristate with leafy appendages.
EUROTIA LANATA, Voq. 1. c. p. 121. Diotis lanata, Pursh, Fl. 2, p.602. With the last,
abundant; September. Hooker refers this to E. ceratoides, but we are inclined to regard it as
a distinct species.
CORISPERMUM IIYSSOPIFOLIUM, Linn.; Moq. 1. c., p.140. C. hyssopifolium, Nutt. Gen. 1, p. 4.
Sandy ravines on the Canadian; also banks of streams, Galisteo, New Mexico; September,
October.
SUEDA MARITIMA, Dumort.; Torr. Fl. N. York, 2, p. 141. Chenopodina maritima, Aoq. in
DC. Prodr. 13, pars 2, p. 161. Salsola depressa, Pursh, Fl. 1, p. 197, excl. syn. Wet saline
soils along the Canadian River; August, September.
SUEDA FRUTICOSA, Forsk.; Moq. 1. c. p. 156. Var.? MULTIFLORA: floribus 6-10 glomeratis,
foliis carnosis compressis. Llano Estacado. A shrubby much branched plant, apparently 3-4
feet high. The branches are of a light-brown color, and marked with little knobs, the cicatrices
of fallen leaves. Lower leaves not seen; those of the primary branches are nearly half an inch
long, and more than half a line wide, compressed, (not semiterete.) The flowers are very
numerous, and are crowded on the axils of the leaves. Sepals oblong, a little fleshy, concave and somewhat cucullate at the extremity, the narrow margin scarious. Seeds horizontal and vertical in the same plant, black and shining, with a short rostrum. We fully
agree with Fenzl (in Ledeb. Fl. Ross. 3, p. 777) in restoring Chen6podina to Suaeda-the only
character on which the former genus was founded being inconstant. There are several other
species of Sunda, in which both vertical and horizontal seeds are found on the same plant.
SARCOBATUS VERMICULARIS, Torr. in Emory's Bep. p. 150, and in Sitgreaves' Rep. p. 169.
Batis? vermicularis, Hoo7k. Alluvions of the Rio Grande, near Albuquerque; October; in
fine fruit.
AMARANTHACE2E.
MONTELIA TAMARISCINA, Gray. Man. ed. 2, p. 370. Amaranthus tamariscinus, Nutt. in Trans.
Anmer. Phil. Soc. (2d ser.) 5,p. 165. Wet ravines, Deer creek, Indian Territory; August.
AMARANTUS ALBUS, Linn.; Moe. in DC. Prodr. 13, pars 2, p. 264. Sandy ravines near the
Canadian River; September.
AMARANTUS RETROFLEXUS, Linn.; Moq. 1. c., p.258. A. greecizans, Torr. Fl7. N. York 2, p.
144. Ravines near Santa Antonito, New Mexico; and prairies (especially around marmot
burrows) along the Canadian River; September, October.
GOSSYPIANTHUS-TENUIFLORUS, Hook. Ic. t. 251; Moq. 1. c., p. 337. Dry prairies near the Cross
Timbers' of the Canadian River. Root-stock stout and dark colored, branching into several
short heads. Stems numerous prostrate 3-4 inches long. Leaves a little pubescent underneath.
Filaments -.very thin and translucent.
FRCELICHrA GRACILIS, Moq. 1. c. p. 420. Dry prairies and rocky places along the Canadian to
the Rio Grande. On Hurrah creek a dwarfform (1-4 inches high.) was found, in which the
inflorescence was reduced to a single terminal cluster or head.
