3I8 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
leaves all basal, very distinct in shape, linear-oblong to linear, rather obtuse 
to very obtuse at the apex, gradually cuneately narrowed into a petiole, the 
blade and petiole together being about 384 mm, long and 5.5 to 4 mm. wide; 
petiole equaling or noticeably surpassing the blade, usually gradually widening 
into it, rather wide, whitish, somewhat puberulent; the blade of the same 
color on both surfaces, grayish-green, entire, at first very finely eglandulose- 
puberulent but finally glabrous, the midrib distinct, especially toward the 
base, the lateral nerves inconspicuous; peduncles 5 to 7 cm. long, slender, 
erect, angled in the dried state, pulverulent-puberulent with eglandulose hairs, 
these very short, moderately dense below and more dense above; heads 
(only those which have finished flowering are present on the specimens) with 
numerous flowers: the bracts like those of 1. fragrans, membranaceous, broadly 
ovate to ovate-elliptical, shortly acuminate, acutish, about 8 mm. long and D 
mm. wide, sparingly pulverulent-puberulent; perianths densely puberulent; 
fruits apparently like those of A. turbinata, 
Collected by Dr. J. M. Bigelow “near Galisteo” ¢ in an expedition made in 
the year 1853 (Lieutenant Whipple’s Exploration for a Railway Route from 
the Mississippi River to the Pacifie Ocean, near the thirty-fifth parallel of 
latitude in 1858-54). Type in the National Herbarium.

Annual: stems ascending, 20 to 40 cm, long, minutely glandular, sleuder ; 
leaf blades broadly ovate to elliptical and deltoid-ovate, obtuse, truncate at the 
base, 13 to 26 mm. long and 12 to 25 mm. broad, almost or quite glabrous ; 
petioles slightly shorter than the blades, glandular; peduncles slender, longer 
than the leaves; bracts broadly elliptical or obovate, obtuse, some of them 
shortemucronate, about 4 mm. long and 38 mm. wide; flowers 1 cm, long, seldom 
longer, their tubes densely pubescent; fruit small, 8 mm. long and 1.5 mm, 
thick, not winged, its body smooth or slightly ridged, rounded or tapering 
above, puberulent. 
This is nearest A. turbinata, from which it can be distinguished by its 
broader, obtuse bracts, its smaller fruit which is not winged but merely slightly 
ridged or more frequently smooth, and its smaller flowers. The plant itself 
is as large as plants of A. turbinata and does not seem at all depauperate.

PLATE XXXVI, Ficure 2. 
Annual: stems puberulent; leaf blades glabrous, broadly elliptical, bright 
green: bracts lanceolate, acute or acuminate, 10 mm. or less in length; flowers 
about 18 mm. long, their tubes greenish, limb greenish-white or pinkish; 
fruit 7 mm. long and about as wide, truncate above, obpyramidal in outline, 
hispidulous at the summit; wings prominent, much wrinkled, with prominent 
vertical nerves; outer fruits sometimes narrowed above into a stout beak.
