This perennial of the aster family of plants has an erect habit of 
growth, and sends up a round, smooth stem about a foot and a half 
high, narrowly grooved and freely branching near the top, each 
branch terminating in a large yellow flower. The branches near the 
flower heads have a slightly reddish appearance. 
The pale-green leaves are about an inch long, of a leathery texture, 
rather rigid, coated with resin, and show numerous translucent dots. 
The leaves are oblong-spatulate (having a gradually narrowed base 
below the broader rounded summit) and are more or less clasping at 
the base, the lower ones somewhat saw-toothed. 
The yellow flowers are borne singly at the ends of the branches and 
measure about three-quarters of an inchacross. The involucre (set of 
small leaves immediately beneath 
the flower) is very resinous and 
consists of numerous thick, over 
lapping scales, the tips of which 
are rolled forward. 
Parts used and prices.—The

and of the scaly grindelia are col-

Description—This species is { 
very similar to the gum plant, _ Fra. 18—Sealy grindelia (Grindelia squarrosa 
with the exception that it is — 
- gmaller and does not have the gummy appearance of the former. The 
slender, erect stems are from 1 to 2 feet high and somewhat sparingly 
branched near the top. The branches near the flower heads appear to ~ 
be somewhat more reddish than in the species previously mentioned. | 
In this species, also, the leaves are not borne on stalks, but are some-
