“cially in M. Californica, namely, that two (opposite) bristles of the pappus are naked 
instead of barbellate, and rather stronger and less deciduous than the others.

Level, grassy places along Santa Fé Creek; June to Aug. —A foot high, from a thick 
perennial root, which yields a white juice; the purplish stem leafy only near the base, 
above nearly smooth and bearing one or two linear bracts. Leaves 2 or 3 inches long, 
sessile ; the radical with a tapering base, hispid with slender bristles above, purplish under- 
neath, resembling those of Hieracium Gronovii, 8. subnudum. Heads two thirds of an 
inch in length. Ligules very short, little longer than the pappus, usually shorter than 
the styles. Mature achenia blackish, a third of an inch long, attenuated upwards, but 
not truly rostrate. Pappus copious, dull white, of bristles nearly as stiff as those of 
Hieracium, but occupying much more than one series;—on which account I refer the 
plant to Crepis (although the pappus is not bright white) rather than to Hieracium.

Fé Creek; July. — Plant with the thick caudex and the aspect of a Troximon; but 
most of the densely clustered leaves (two or three inches long) bear a few short linear 
lobes about the middle. Scapes at length glabrous. Heads cylindraceous, two thirds’ 
of an inch long; the scales of the involucre mottled or spotted, or the broader exterior 
ones entirely painted, except the margins, with deep purple. Flowers purple ; the ligule 
viridi scariosis late ovalibus obtusissimis, intimis lanceolatis acutis. — California, Coulter. — A foot high, 
a We root unknown. Leaves 2 inches long. Heads 10 lines in diameter. Flowers, ovaries, and pappus 
as ii lacothrix; but the scarious involucre is yery remarkable. .The fruit is unknown. 
Remarkably large specimens of Malacothrix Californica, with coarser foliage, and the head, including thea 
expanded rays, two inches in diameter, were collected by Dr. Gambell at Pueblo de los Angelos and distributed 
under the name of “ Macrorhynchus laciniatus.”
