none: pappus of many unequal persistent and not fragile 
bristles. 
Inhabiting rocky summits of the Californian Coast Range, 
from near Berkeley, where it was discovered by the writer in 
the summer of 1881, to Mt. St. Helena and the whole adjacent 
mountain region ; also southward in Monterey County, whence 
it was sent, in a very densely leafy and almost white-pubescent 
state, by Mr. Hickman, in the year 1887 ; flowering in August 
and September. The plant recedes greatly from all ordinary 
types of Erigeron in its autumnal flowering, and more 
especially in its very multiserial and closely imbricated invo- 
lucral bracts; these appearing in as many series as in any 
species of Aster. It is nevertheless but one of a group of 
several very peculiar Californian species of Erigeron; E. 
angustatus’ having quite as imbricated an involucre ; E. vis- 
cidulus, which, although with fewer and less imbricated 
bracts, is the nearest ally of the present plant, and E. inorna- 
tus ; all four being leafy and discoid perennials of peculiar 
habit, and autumnal in their flowering. 
CacaLta PaLmeRI Two feet high, stem simple up to the 
corymbose summit, scapoid, striate, very slightly tomentose- 
pubescent, the leaves equably so on both faces : leaves few 
and sub-radical, from broadly ovate to almost orbicular, 
cordate, obtuse, with shallow sinuate and mucronately denti- 
culate lobes, 3 to 6 inches long, of coriaceous texture, the 
petioles stout and nearly as long : heads small, few-flowered, 
crowded in cymose terminal clusters: flowers apparently 
white. 
Rio Blanco, State of Jalisco, Mexico, 1886, Dr. Edward 
Palmer (No. 168). C. lussilaginoides, to which this has been 
hastily referred, has broadly reniform and multifid leaves 
which are white-tomentose beneath ; therefore about as 
different as possible from those of this new species.
