170 PITTONIA. 
doubt among such will ultimately be found the types of two 
or three other species, when they become better known. It 
appears that some plants quite equivalent to my A. denudata 
var. canescens were also included in Gray’s var. incana. 
A. BERNARDINA. Nearly allied to the last, and with 
similarly bunched coarse, even fleshy-fibrous roots, tufted 
basal leaves, etc., but only cinereous with a fine tomentose 
pubescence, this here and there overspread with some long 
arachnoid hairs, especially the leaves beneath; foliage 
larger, more elliptic-lanceolate, and more conspicuously 
denticulate or dentate: heads still larger, nearly $ inch 
high and an inch broad; involucral bracts oblong, obtuse, 
much shorter than the disk: rays relatively larger than in 
either of the last two, somewhat villous on the outside, 
8-nerved, 3-toothed: disk-corollas with long villous tube 
and much shorter broad and almost campanulate glabrous 
throat: achenes only sparsely short-setulose, not glandular; 
pappus long, dull-whitish, barbellate. 
This local subspecies, several times distributed by Mr. 
Parish, from Bear Valley of the San Bernardino Mountains, 
southern California, under the name of A. foliosa, is marked 
by large and long acute leaves along with which go the 
most short and obtuse of involucral bracts seen in this 
genus, 
A. ATTENUATA. A foot high, sparingly somewhat villous- 
pubescent, most so upon the stem and the margins and 
veins of the narrow leaves, the latter in mostly 3 or 4 pairs, 
narrowly lanceolate-acuminate and linear-acuminate, entire, 
3-nerved ; the two upper pairs much reduced, the longest of 
the lower 2 or 3 inches long: heads 8 to 5, the lateral ones 
later than the terminal and their peduncles bibraeteate: 
bracts of the campanulate involucre narrow-lanceolate,
