length of the tube; anthers 3 mm. long, blackish, the base slightly 
sagittate, the whitish triangular cartilaginous appendages partly 
folded; style-branches 2 the length of the lower portion, includ- 
ing the triangular acute appendage, oblanceolate, pubescent; base 
of style bearing a dark bulb-like enlargement which disarticulates 
from the akene; mature akene not seen, apparently the outer nar- 
rowly 3-winged, the inner narrowly 2-winged; pappus a single 
seta from each angle, the lower portion concealed by the similar 
© setae which densely clothe and surpass the akene. 
This very peculiar species is in its alternate leaves, and general 
vegetative characters, and its sharply angled or perhaps winged 
akenes, most unlike the genus to which I have referred it, but I 
am disinclined to multiply genera in this perplexing sub-tribe, un- 
less the receipt of additional specimens with mature akenes may 
render it necessary in this instance. 
974. VERBESINA BRIDGESII sp. n. 
. Stems erect, light green, coarsely angled, pubescent with short, 
someweat retrorse hairs; leaves 7-14 cm. long, 2-5 cm. broad, 
. ovate or the upper lanceolate, the apex tapering to an acute point, 
the base abruptly contracted into a narrow portion, which is clasp- 
ing and auriculate, the auricles glandular-viscid, coarsely and ir- 
regularly toothed, thickish, rugose-reticulated, grayish-green or 
slightly yellowish, above scabrous, below soft-tomentose; inflor- 
escence tomentose, the heads compactly arranged, 7 mm. long, 
nearly 1 cm. broad, the involucre hemispherical, the scales in 3 or 
4 series, spatulate-oblong, with rounded green tips; rays about 
10, white, 5 mm. long, oval or nearly rotund, with 3 slight rounded 
teeth, 3-5-nerved ; scales of the disk obovate, acuminate, the apex 
ciliate or lacerate, hyaline, finely many-nerved, as long as the disk 
flowers; disk-corollas 6 mm. long, regularly narrowly funnelform, 
the lobes small, triangular ovate, obtusish; anthers slightly ex- 
sert, black, 2 mm. long. Mature akene not seen. All these 
characters to be slightly modified as the flowers described are 
rather immature.
