Perennial %; stems spreading, very slender, almost or quite glabrous: leaf 
blades very narrowly elliptical or oblanceolate, glabrous, obtuse, gradually 
narrowed towards the base, 18 mm. long and 3 to 6 mm. wide; petioles shorter 
than the blades, glabrous: peduncles about 85 mm. long, glabrous or scantily 
and minutely puberulent; bracts 5, narrowly lanceolate, acuminate, puberulent, 
scarious, 7 mm. long and 2 mm. wide or less: flowers 12. to 15, 15 to 20 mm. 
long, limb 6 mm. wide, tubes puberulent; fruit broader than long, its body not 
coriaceous; the wings very broad, much narrowed below, produced above the 
body of the fruit; outer fruits with very narrow wings which are widest in 
the middle and narrowed above and below, the wings thin and soft. 
This differs from A. umbellata in its more glabrous and slender stem, larger 
bracts, and narrower and more glabrous leaves, while the fruit has wider and 
thinner wings which are prolonged above the body. Type U. 8S. National Her-
