2a little narrowed below, acute, very setose, twice as long as the oblong- 
te pods. ied elliptical, 1mm. long, acutish at both ends, conspicuously 
siecalate pitted, 
Genitiopappas flavescens is described as biennial. It surely is a per- 
ennial. 
ahia depressa N. Sp. A low perennial a few inches high and much 
branched from the base, with short internodes and overlapping leaves which 
are about an inch long and spatulate and entire, and but little reduced above. 
Whole plant white-floccose even to the involucre. Heads terminal and lateral, 
on stout peduncles about as long as heads which are 4 inch high. Bracts 
of involucre oblong, erect and rather rigid, not spreading in fruit, with about 
3 yellowish glands toward the tip (not visible except on looking through the 
bracts), forming a cup from which the ripened flowers fall. Rays several, 
yellow and about half as long as the heads, fertile and with the fruit in- 
clined to be flattened and black. Pappus of about 5 scales tapering into 
denticulate awns as long as the body. Seeds appressed-pubescent. Growing 
on Cliffs near the Devil’s river, Texas, April 22, 
Stephanomeria minima N. Sp. A weak and wae speetine annual, di- 
yatiseicly much branched, a few inches high, leaves clustered at base 
mostly, the stem ones much reduced and bract-like. Basal leaves lanceo- 
inch long and dear bracted above the middle. Heads 4mm. long, smooth, 
light yellow, linear, with 4 linear bracts a little flaring at tip and purplish 
there, green, and with a single broad bract at base. Flowers 4. Akenes 
linear, truncate, not rugose but minutely roughened, with 4 strong ribs flat- 
tish on the top, aes rib with a very thin and raised central line and with 
as minute single grooves on each side, yellow, pappus consists of a ring 
of white bristles, Cheit 20 to 25 in number which are barbellate but not 
plumose, which come off from the akene in a body. Bristle about as 
long as the akenes, which are as long as the involucral arn Growing 
on the clayey plains at Fredonia, Arizona, June 1, 1929. This no doubt 
has been lumped in with S. exigua.
