254 PITTONIA. 
v B. ELEGANS. Stems a foot high, slender, sparingly 
branched from above the middle, terete, glabrous, red-pur- 
ple: leaves narrowly lanceolate, about 3 inches long and 
with seldom more than 3 pairs of teeth, these short but sali- 
ent: heads of middle size, strongly cernuous on slender and 
notably elongated peduncles: outer bracts of involucre greatly 
reduced, not as long as the inner, spreading or deflexed: 
rays 6 to 8, narrowly oblong-linear, of thrice the length of 
the involueral braets and golden-yellow, 10-nerved: disk- 
corollas with slender tube, short unceolate throat and long 
teeth or segments, the latter erect: achenes of the outer 
series 4-angled and -awned, of the inners 3-awned, the 
angles not cartilaginous-thickened, retrorsely aculeate like 
the awns, the surface greenish brown and rather coarsely 
striate. 
Known to me only as collected near Northwest, Norfolk 
Co., Va., 8 Nov., 1898, by Mr. T. H. Kearney, whose speci-

narrow rays. The habit, the foliage, and the achenes are 
all characteristic. 
Y B. tucens. Two feet high, slender, freely loosely and 
and widely branching, the scabrous stem and branches green 
and striate: narrowly lanceolate leaves 3 to 5 inches long, 
widely spreading, lightly and not very closely serrate- 
toothed: heads slender-peduncled and nodding: bracts of 
outer involucre spatulate, serrulate, exceeding those of the 
inner series but hardly equalling the 7 to 10 large and 
broad bright-yellow rays: disk-corollas with long tube and 
much shorter limb, the latter much surpassed by the tube 
of long blackish anthers: achenes blackish, narrowly obo- 
vate-cuneiform, marginless, all but the outermost merely
