74 [130] BOTANY. 
OBIONE PoLycaRPA, Torr. (in Emory’s 1st Report, p. 149, sine char.): suffruticosa, ramosissima ; 
ramulis gracilibus paniculatis ; foliis minutis sessilibus obovato-oblongis obtusis integerrimis 
albido-farinosis ; bracteis orbicularibus, supra mediam distinctis argute grosse-dentatis, utrinque 
cristatis. With the preceding. Leaves 3-5 lines long, crowded. Fruit abundant, aBeEegnion 
on the long slender branchlets. Fructiferous bracts about 2% lines in diameter. 
Oprone caNEscens, Mog. 1. c. p. 212. Llano Estacado; September ; fruit. The specimens 
belong to the form with broadly winged fruit-bracts. 
. OBIONE ARGENTEA, Mog. |. 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 wckienlan the margin deeply and acutely toothed, and the disk is often 
more or less cristate with leafy appendages. 
Evrotra tanata, Mog. 1. ¢. p. 121. Diotis lanata, Pursh, FI. 2, p. 602. With the last, 
abundant ; September. Hooker refers this to E. ceratoides, but we are inclined to regard it as 
a distinct 1 species.

Suapa Fruticosa, Forsk.; Mog. l. ec, p. 156. Var.? muxarriora: 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 wae compressed, (not semiterete.). The flowers are very 
- numerous, and are crowded on the axils of the leaves. Sepals oblong, a little fleshy, con- 
cave and somewhat cucullate at the extremity, the narrow margin ‘scarious. Seeds hori- 
zontal 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 Chenopodina to'Suada—the only 
character on which the former genus was founded being inconstant. There are several other 
species of Suzeda, in which both vertical and horizontal seeds are found on the same plant.
