HorKELIA BOLANDERI marinensis, n. var.—Tufted perennial, 
r to 2% high, villous pubescent: stems deflexed and more or less 
decumbent: leaves pinnately divided into 5 to 8 pairs of leaflets, 
subradical though often the stem bears as many as 3 to 5 leaves with- 
out subtending branches; average leaflets 10o™™ long, unequally 4 to 
1o-toothed; basal stipules narrowly linear, 1o™™ long, those on the 
stem broader and usually 1 or more-toothed: inflorescence branched 
from near the middle, corymbosely paniculate; branchlets loosely 
flowered: hypanthium longer than wide, saucer-shaped; bracts 
broad, 3-toothed: stamens 10, opposite the outer and inner series of 
sepals which must exceed them: outer sepals shorter, spatulate or 
acute at apex, pubescent on both sides; inner ones acuminately 
triangular, glabrous on the inner surface: filaments glabrous, flat- 
tened, slightly unequal in length; anthers introrse, short, elliptic: 
petals white, narrowly spatulate or oblanceolate, about equaling the 
sepals, early falling: styles many, glabrous, erect: seeds bean-shaped, 
smooth. | 
Type specimen no. 5039, collected in sandy soil at Point Reyes, Marin 
County, California, July 1903. 
This variety has been distributed as H. Parry: (Wats.) Ryd. It has the 
pubescence of typical H. Bolanderi Gray, but the stems are more or less decum- 
bent, basal stipules strictly linear and almost twice as long as in the species, 
leaflets larger and more toothed, and inflorescence more loosely corymbose and 
with larger hypanthia. 
Chrysopsis arenaria, n. sp.—A wiry perennial herb, from creep- 
ing and much branched roots: stems 10°" long or very much 
shortened and bearing a dense rosette of leaves, erect or more often 
subreclining, hirsute: basal leaves soon withering; cauline ones 
many, ascending, obovate to oblanceolate, the lower ones slenderly 
attenuate from the base, alternate, entire, hispidly hirsute on both 
sides, ascending: heads heterogamous, terminating the stems, 1 to 
3, barely exceeding the leaves, upon densely hirsute often glandular 
and few-bracteolate peduncles, 15™™ in diameter, nearly that in 
length; jinvolucre of several series, campanulate; bracts linear, 
imbricate, acuminate, pubescent, the longer ones 107™ in lengt 
and usually with pink scarious margins: receptacle flat, favose: ray 
flowers in one series, pistillate, showy; ligule yellow, 4-nerved, narrow- 
ly oblanceolate, entire, 6™™ long; its tube slender, 5"™ long, glab-
