one much longer than the others, 4’ long and 3” wide ; upper leaves sessile, 
3-parted ; outer series of involucral scales lanceolate, ciliate, as long as the 
broadly margined inner series. Flowers in my specimen are all too young. 
Mr. Watson has kindly compared it for me, and pronounces it the same as 
1233 of Mr. Wright’s collection.

Scabrous-pubescent; stems diffusely branched, a foot high; branches sim- 
ple; leaves alternate, broadly ovate, 2-3 lines long, smaller upon the 
branches, entire, very shortly petioled; heads large, 2—3 lines in diameter, 
terminal and solitary, discoid, many-flowered ; achenia compressed, hispid ; 
pappus none——With nearly the habit of the last. Nevada.” I have 
quoted the description from Mr. Watson. The specimen I have not seen.—

as well as glandular: leaves round-cordate or fan-shaped in outline, 5-9- 
cleft and the lobes copiously incised, the upper alternate and less lobed: 
scales of the involucre rather broad: rays short, white, broadly oval: style-

* « PerITYLE, Benth.—Heads many-flowered, with pistillate rays, or occasionally none ; the flowers 
all fertile. Involucre campanulate, of nearly equal scales, slightly carinate on the back, in a single or 
double series. Receptacle flattish or conical, naked. Rays 3-toothed; disk-ccrollas 4-toothed; the tube 
glandular. Style-branches tipped with (or insensibly changing into) a short and obtuse or more com-

flowers, all mane Involucre narrow, cylindraceous, of 4 to 10 linear-oblong and coriaceous equal 
woolly scales, which are connivent but distinct, except at the very base, and a few thinner or scarious 
ones within, sometimes a narrow external bract or two. Receptacle flat, naked and smooth. Rays 
large for the size of the head, very broad, abruptly contracted at the base into a short tube, truncate and 
3-lobed at the end, 5-7-nerved (the nerves converging and uniting in pairs within the lobes), becoming 
papery, persistent on the akene. Disk-corollas elongated-cylindraceous, with a very short proper tube, 
5-toothed at summit; the teeth glandular. Anthers linear, minutely sagittate, or emarginate at base.
