16 : PITTONIA. 
rior of California near Fresno, April, 1884, and at the time re- 
ferred to my then recently published M. acuminata ; from which 
it must needs be held distinct on account of its smoother achenes 
and villous pappus-pales, this last being a new character for a 
species of this group. 
M. oBTUsATA, Stoutish, low, perhaps sometimes depressed 
the scapes 3 to 7 inches high, the flowering ones almost equalled 
by the leaves, these somewhat lyrately pinnatifid, the large ter- 
minal segment oval, the others more nearly oblong, all very 
obtuse, mucronulate: involucres more than } inch high, sub- 
globose, the calyculate outer series of bracts uncommonly large 
for the genus, and imbricate in two or three series: achenes 
subclavate-cylindric, 2 lines long, the outer strongly villous in 
lines, the inner with ribs scabrous-serrulate, light brown, flecked 
with short linear dots of purple; pappus of subquadrate-lanceo- 
late lacerate-toothed translucent but dark smoky-brown palee 
and almost twice longer awns. 
Bodega Point, Sonoma Co., Calif., 1899 and 1900, Miss East- 
wood. Perhaps also the same, by the same, from Point San 
Pedro, San Mateo Co., 1899; but this last has darker spotless 
achenes and a rather different almost entire pappus-pale. 
M. MARITIMA. Near the last, larger, but much more slender, 
commonly much depressed: leaves mostly of oblanceolate out- 
line, the lowest often quite entire, some merely dentate, the 
greater number pinnatifid, but leaving a large oblong or oval 
obtuse entire terminal lobe: heads round-ovoid, less than } inch 
high :achenes narrow-turbinate, only 13 lines long, the outer 
silky-villous, the others partly with obtuse smooth ribs and partly 
with ribs more acute and finely scabrous-serrulate; pappus- 
palex ovate-trigonous thin, white, subentire, scarcely a line long 
terminating in an awn of almost 3 lines. 
On open bluffs overhanging the sea at Pacific Grove, Monterey 
Co., Calif., 27 May, 1895, collected by the writer.
