MICROSERIS § NOTHOCALAIS Gray. 
Acaulescent perennial herbs with linear leaves and middle- 
sized erect heads of yellow flowers. Involucre oblong-campanu- 
late; its bracts in two series, narrowly lanceolate, membranace- 
ous with somewhat thinner hyaline margins, nearly equal. Re- 
ceptacle flat, alveolate. Achenes fusiform, stipitate, contracted 
or rostrate-attenuate at summit, 10-costate. Pappus very white 
and soft, of 10-40 scabrous-margined narrow unequal pales with 
or without some capillary bristles. 
N. Suksdorfii Greene l. c.: More or less pubescent: scapes 4-10 inches 
high: leaves linear, attenuate nearly equalling the flowering scapes, all 
from the crown of a thick perennial root: bracts of the involucre lanceolate, 
long-attenuate, 6-12 lines long: achenes slender, 5-6 lines long, only half 
filled by the seed: palez of the pappus 10-12 narrow and nearly equal. 
Plains of Klickitat Co. Washington and adjacent Oregon. 
N. troximoides Greene 1 c. Microseris troximoides Gray. Scapose 
stems 6-12 inches high: leaves tufted on the crown of a thick perennial 
root, rather fleshy, narrowly linear-lanceolate, entire or undulate, 4-6 
inches long: achenes fusiform, scarcely 4 lines long, its summit merely 
contracted, nearly filled bv the seed: palez of the pappus 20-24, lanceolate 
below, very unequal half-inch long. Plains and hillsides eastern Oregon 
and Washington to California and Idaho. 
N. cuspidata Greene l.c. Troximon cuspidatum Pursh. Scapes stout, 
shorter than or equalling the leaves: leaves linear, long-acuminate, thick, 
pubescent or glabrate, 4-8 inches Jong, 2-5 lines wide, somewhat condupli- 
cate, their margins wbite-tomentose and crisp, or entire: involucre usually

103 MALACOTHRIX DC. Prodr. vii, 192. 
Leafy-stemmed or sometimes scapose herbs with alternate or 
all radical leaves and long-peduncled, panicled or solitary, heads 
of yellow or white flowers that are usually nodding in the bud. 
Involucre many-flowered, its bracts either imbricated or only 
calyculate. Receptacle with or without delicate capillary brist- 
les ameng the flowers. Achenes not flattened, short-oblong or 
columnar, glabrous, terete and striately 5-15-costate, or 4—5-an- 
gled by the prominence of the stronger ribs, slightly if at all 
narrowed eithcr way with broad truncate apex having an entire 
or denticulate border or sharp edge. Pappus a series of soft and 
scabrous, or near the base barbellulate, bristles which are decid- 
uous more or less in connection, and commonly 1-8 outer and 
stouter ones which are more persistent and smoother. 
M. glabrata Gray Syn. Fl. i, pt. 2, 422. Subcaulescent annual: erect 
or with ascending branches from the base, these leafy, often again branch- 
ing and bearing a few lateral as well as terminal long-peduncled heads of 
yellow flowers: leaves once or twice laciniately pinnatifid into narrow linear 
or almost filiform lobes: involucre fuily half-inch high, glabrous, or the 
outer bracts sometimes canescent when young: achenes narrow, lightly
