1900] EASTWOOD—CALIFORNIAN PLANTS 293 
This seems most distinct from all the other species in having the involucral 
leaves almost closing over the flowers, the peculiar concave or truncate top to 
the bracts enclosing the fertile flowers, and in the more veiny and membranous 
foliage, less woolly pubescence, and more slender habit. 
~ Senecio Millikeni, n. sp.—Stems tall, glabrous, hollow, ribbed, 
paniculately branched, the slender virgate branches leafless in 
the lower part: leaves linear-lanceolate, narrowed at both ends, 
with acute apex, sessile base, margin dentate with small uneven 
obtuse teeth, the lower 12°™ long, 2.5°™ wide, diminishing up- 
wards: panicle thrysiform, the peduncles and pedicels slender, 
bracts and bractlets attenuate, equaling or longer than the slender 
pedicels: heads 1°™ high, bracteate at base, the involucre 5™™ 
high, with glabrous scales tipped at apex with a tuft of tomentum; 
rays 6, 3-toothed, 7™™ long, style exserted 3™™; disk flowers 
7™™ long, the acute triangular teeth of the corolla slightly gran- 
ular, stamens exserted but style branches surpassing them: akenes 
glabrous; pappus soft and abundant, about as long as the corolla. 
Type collected in Natural Bridge Meadows, Tulare County, California, by 
Culbertson, Aug. 10, 1904, C. F. Baker’s distribution 4268. It is named in 
honor of Mr. Culbertson’s assistant. 
This belongs to the polymorphous group of which S. triangularis was the 
first described. It differs from all in the narrowed bases of the leaves, the thyr- 
siform inflorescence, and the smaller heads.
