GRINDELIA MACROPHYLLA. Stout erect herbaceous, 3 feet 
high, corymbosely branched at summit, wholly glabrous, or 
with a few scattered short hairs on the pedunculiform 
branches: leaves thinnish, the radical a foot long or more, 
lanceolate, scarcely petiolate, incisely serrate; the cauline 
oblong or spatulate-oblong, 2 to 4 inches long, sessile and 
clasping by a broad base, coarsely serrate, or the uppermost 
reduced and entire: involucres large, hemispherical, scarcely 
glutinous, their narrow bracts with a long slender spread- 
ing acumination: rays many, an inch long or more. 
Large and handsome species, obtained by the writer along 
the margins of a tide-water swamp near Vancouver, British 
Columbia, in July, 1890. 
GRINDELIA SUBALPINA. Low perennial, the stoutish 
corymbose-panicled stems seldom a foot high, only sparingly 
leafy except at base; lowest leaves oblanceolate, petiolate, 
acute, coarsely and remotely incised, usually scabrous- 
puberulent; the few cauline oblong-spatulate, rather re- 
E motely and sharply serrate, glabrous: depressed globose 
heads rather large; bracts of the involuere numerous, with 
filiform squarrose-spreading tips, the whole very glutinous : 
rays numerous, narrow: bristles of the pappus 2 to 4, 
slender, barbellulate. 
High plains of southern Wyoming, and at subalpine ele- 
vations on the mountains of northern Colorado. Hitherto 
confused with G. squarrosa, which is wholly of the plains, 
strictly biennial, branching and very leafy, perfectly gla- 
brous, and with stouter smooth pappus-bristles. 
GRINDELIA PLATYLEPIS. Probably perennial, stouter and 
taller than the last, glabrous throughout, not at all gluti- 
. nous: heads rather small; involucre almost hemispherical, 
. usually closely subtended by one or more large leafy bracts, 
its proper bracts or scales ovate or oblong, abruptly herba-
