1. Hesperonia cedrosensis Standley, sp. nov. 
Stems stout, apparently dichotomously branching, more or less scorpioid, cov- 
ered with a pubescence consisting of scattered, flattened, whitish hairs: inter- 
nodes shorter than in H, laevis; leaf blades narrowly triangular or subhastate, 
30 mm. or less in length and 18 mm. wide or less, more or less wavy-margined, 
acute at the apex, mostly truncate to subcordate at the base, thick, with a few 
scattered, flattened hairs on both surfaces; petioles very short, some of the 
uppermost blades almost sessile; flowers sessile or on very short peduncles, 
sometimes subtended by bract-like leaves, solitary or sometimes clustered ; bracts 
7 mm, long or less, the free portion shorter than the tube, rather narrowly tri- 
angular, acute, densely scabrous; flowers about 12 mm. long; stamens included ; 
fruit subspherical, rather larger than that of H. californica, dark brown in 
color marked by 10 lighter vertical lines. ; 
Type in the herbarium of the University of California; collected on Cedros 
Island, California, April 3, 1897, Brandegee, The same is in the Nationnl 
Herbarium, collected at the same locality in 1889 by Palmer. <A plant dis- 
tinguished by its subglobose fruit and scabrous pubescence. 
Here belong, probably, the following collections: 
CALIFORNIA: San Clemente Island, 1903, Mrs. Blanche Trask 193; same 
locality, 1902, Mrs, Blanche Trask 14; same locality, 1894, Brandegee, 
2. Hesperonia aspera (Greene) Standley. 
Mirabilis aspera Greene, Erythea 4: 67. 1896, 
Stems stout, dichotomously branched, roughly retrorse-pubescent, leaf blades 
ovate, subcordate, thics, rough-puberulent, 25 mm. long and 18 mm. wide or 
less, obtuse or the uppermost ones subacute; petioles very short, some of the 
blades almost sessile; inflorescence dichotomously branched, dense: flowers on 
stout peduncles about 5 mm, long; bracts thick, narrowly to broadly ovate, 6 to 
7 mm. long, the free portion about as long as the tube, the involucre about 6 
mm. in diameter when distended by the fruit; flowers about 1 cm. long; fruit 
globose or subglobose, about 5 mm. in diameter, dull olive-green marked by 10 
lighter vertical lines. 
This species is distinguished by its thick, obtuse, almost sessile, rather nar- 
row leaves, stout stems, rough pubescence, spherical or subspherical fruit of 
peculiar color, and its thick bracts.
