364 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
as the blades; flowers on peduncles almost as long as the involucre; bracts 
lanceolate, acute, the free portion as long as the tube, finely and densely 
puberulent, the whole about 9 mm. long; flowers about 12 mm. long, the stamens 
long-exserted ; fruit cylindrical; acutish at both ends, dark brown, smooth, T 
or 8 mm. long, and almost 38 mm. thick. 
From H, polyphylla this differs in its obtuse lower leaves, which nre some- 
times cordate at the base, thinner blades, less pubescent stem, longer and nar- 
rower fruit, and fewer flowers; from //. tenuiloba, in its more slender stems, 
obtuse lower leaves, thinner blades, and longer and narrower fruit. Type in the 
herbarium of the University of California, collected at Calmalli, Lower Cali- 
fornia, 1898, Purpus 82. 
6. Hesperonia polyphylla Standley, sp. nov. 
Perennial; much branched from a woody base, the lower branches suffrutes- 
cent; stems stout, glabrous below, finely short-pubescent above, not viscid, the 
nodes swollen and conspicuous, the internodes short: leaf blades ovate, acute, 
rounded at the base, glabrous or the younger ones sparingly puberulent, thick 
and fleshy, the lateral veins inconspicuous; blades small, less than 20 mm. long 
and about 10 mm. wide; petioles not more than one-third as long as the blades, 
stout; most of the flowers on peduncles which are about as long as the invo- 
lucre; bracts lanceolate or ovate-lanceolate, the free portion about as long as 
the tube, the whole about 9 mm, long, thick and puberulent: flowers about 2 em, 
long and almost as wide; the stamens included; fruit oblong in outline, broadly 
obtuse at both ends, smooth, brown, about 4 mm. long and almost 8 mm. wide. 
From i. tenuiloba this differs in the smaller size of the plant, shorter inter- 
nodes, more leafy appearance of the plant, smaller and thicker leaves which 
are not cordate at the base, and the broader segments of the involucre. The 
internodes near the ends of the branches are very short, so that the branches 
are densely leafy; there is a flower in almost every axil and at least one at each 
node, so that the flowers appear numerous. Type in the herbarium of the 
University of California, collected at San Borga, Lower California, May 6, 1889, 
Brandegee. On the same sheet is what appears to be the same plant, collected 
at Los Angeles Bay, Gulf of California, 1887, Palmer 600,
