twice as long as the leaves; involucre 4 mm. high, subcylindric, its 
bracts in 2 or 3 series, linear, puberulent, the outer shorter than 
the inner; ligules white; disk-flowers tubular, 5-lobed, the lobes 
obtuse; achenes flattened, oblong or somewhat oblong-elliptic, 
minutely hispidulous; pappus-bristles in 1 series, barbellate 
In white sand, vicinity of Los Indios (Britton & Wilson 14207). 
Helenium scaposum sp. nov. 
A low, pubescent, scapose perennial. Leaves several or many, 
densely tufted, short-petioled, oblong to spatulate, punctate, 1.5-3 
cm. long, 6-10 mm. wide, rather strongly 5- to 7-nerved, entire or 
repand-dentate, obtuse or acute at the apex, narrowed or cuneate 
at the base; scapes rather stout, 5-11 cm. high; involucre about 5 
mm. high; its bracts ovate-lanceolate, acute, appressed or little 
spreading; rays 10 to 12, bright yellow, obovate, 3-toothed, 5-8 mm. 
long; disk yellowish, depressed-globose, 8-12 mm. in diameter, its 
corollas 5-lobed, the lobes triangular-ovate; pappus scales of ray- 
flowers and disk-flowers alike, elliptic to obovate, lacerate, not 
aristate. 
White sand pine-lands, west-central districts. Type from near 
Siguanea (Britton & Wilson 14346). 
A plant with quite the floral structure of Helenium, but its 
scapose habit is aberrant, resembling that of some Tetraneuris 
species.
