. 6. Abronia salsa sp. nov. 
Abronia fragrans S, Wats. King’s Rep. 5: 284. 1871. Not 
Nutt. 
Perennial : stem ascending, 3-4 dm. high, densely viscid-pubes- 
cent especially above, stout: leaves very thick, puberulent ; petioles 
2-3 cm. long ; blades oval or elliptic, obtuse, or the lowest rounded 
oval, 3-5 cm. long, 1-3 cm. wide : peduncles 5—7 cm. long, densely 
viscid-pubescent ; bracts rounded obovate, about 15 mm. long and 
often as broad, pubescent: flowers many, about 2 cm. long witha 
limb about 4 mm. wide : fruit about 1 cm. long, similar to those of 
A, lanceolata and A. fallax but the wings are rather thicker. 
The sheets in the National Herbarium bear the following Jabel- 
ing by Dr. Heimerl : ““Adronia fragrans Nutt. (ad formam ellip- 
ticam (Nelson) accidens /);” but neither A. sa/sa nor A. elliptica 
A. Nelson have the fruit of 4. fragrans, and therefore can not be 
regarded as forms of that species. A. salsa differs from A. eéliptica 
in the stouter viscid-pubescent stem, the larger bracts and flowers. 
It grows in sandy saline soil at an altitude of 1000-1300 m.

mm. wide and 8 mm. long, cuneate-obpyramidal. 
The type in the U. S. Nat. herbarium bears the following tf 
marks from the hand of Dr. Heimer]: “ Adronia fallax m.—? Hy- 
brida ex A. fi ragrans et A. turbinata.— Ab A. fragrans anthocar-
