§ 3. H e a d s entire ly dioecious: p a p p u s o f the sterile flow e rs mostly s tro n g ly
clavate : stems ccespilose, often surculose, or stoloniferous.—Catipes, D C .
2. A . luzuloides : silky-villous throughout; sterile stems or stolons none ;
leaves linear, obscurely 3-nerved, tapering to the base ; corymb compound,
loose; sterile heads small; the exterior scales of the glabrous involucre
short and rounded ; the inner ones spatulale, with dilated and very obtuse
white tips.
Oregon or Rocky Mountains. (Drummond or Douglas.)—Stem 10 inches
high, slender, simple, clothed like the leaves with a close appressed silky
pubescence. Leaves 2-3 inches long, 1-2 lines wide. Heads numerous
(40-50) in an open compound corymb, not more than half the size of those of
A. Carpathica: the scales of the involucre not sphacelate or eroded. Pappus
not denticulate or scabrous ; the tips very much dilated and spatulate.—Although
most related to Hooker’s striking var. pulcherrima of the following
species, yet it has very much smaller and glabrous heads, and narrower
leaves ; and widely differs from the original A. Carpathica. We have only
seen the staminate plant.
3. A. Carpathica (R. Br. 1. c .): sterile stems not stoloniferous; leaves
lanceolate, or the radical oblanceolate, 3-nerved, villous-tomentose ; corymb
capitate; involucre very woolly and turbinate at the base, brownish,
the inner with elongated and shining sphaeelate-scarious (often white)
tips, which are obtuse in the sterile, but acute in the fertile heads.

5. A . dioica (Gaertn.): sterile Stems stoloniferous; leaves silvery-tomen-
tose-canescent on the lower or on both sides (commonly glabrous above) ; the
radical spatulate, one-uerved or 3-nerved at the base; the cauline linear-
lanceolate, appressed; heads several, in a capitate corymb ; scales of the involucre
with erose-denticnlate mostly obtuse (white, ochroleucous, rose-color,
or purple) tips; achenia perfectly smooth.—Geertn. fr . 2. p. 410, t. 167;

6. A. plantaginifolia (Hook.! 1. c .): sterile stems stoloniferous or flagelliform,
the flowering simple and scape-like; leaves silky-villous on one or
both sides when young, but when old glabrous above and canescent beneath ;
the radical petioled, oval or obovate-spatulate (usually large), 3-nerved ; the
cauline lanceolate, appressed; heads in a small crowded corymb; scales of
the involucre with white (rarely purplish) erase or crenulate tips; those of
the sterile plant obtuse, of the fertile narrow and mostly acute ; achenia minutely
glandular-papillose.—A. plantaginea, DC. ! l.c. Gnaphalium plan-

Near Philadelphia, Mr. Lea! See. April-May : in the Southern States,
Feb.-March.—Plant 4-10 inches high. Radical leaves often 2-3 inches
long, and one or two wide. Pappus of the sterile flowers sparsely barbellate,
more or less evidently thickened towards the apex.—Plantain-leaved
Cud-weed.
7. A. racemosa (Hook.! 1. c.) : sterile stems stoloniferous; leaves tomen-
tose beneath; the upper surface and the scape-like stem nearly glabrous; the
radical oval or obovate-spatulate, petioled, somewhat 3-nerved ; the cauline
oblong or lanceolate ; heads loosely racemose-paniculate ; scales of the involucre
nearly glabrous, greenish; those of the sterile plant obtuse; the inner
of the fertile heads narrow and acute; achenia perfectly smooth.
Alpine woods of the Rocky Mountains (probably about lat. 52°), Drummond
!—Fertile plant often a foot or more in height; the heads loosely disposed
in a long racemose panicle. Pappus in the sterile heads minutely
scabrous, very obscurely thickened above: the style slightly 2-cleft at
the apex.
8. A . dimorpha: csespitose, depressed, somewhat stoloniferous; leaves
crowded on the short branches of the suffruticose caudex, oblong-spatulate or
nearly linear, silky-villous; heads solitary, on short peduncles, scarcely ex-
serted beyond the leaves; scales of the involucre brownish, the exterior
woolly; the inner scarious, lanceolate, acute in the sterile, and acuminate
in the fertile heads; pappus of the former capillary, sparsely and minutely
barbellate towards the apex.—Gnaphalium (subgen. Omalotheca, § Hefero-
phania) dimorphum, Nutt.! in trans. Amer. phil. soc. (n. ser.) 7 .p . 405.
Black Hills of the Platte, Nuttall! May.—Plant 1-3 inches high. Leaves
an inch long; in the fertile plant 2-3 lines, in the sterile scarcely a line wide.
Heads twice as large as in Gnaphalium supinum.—This plant appears to
our view a genuine Antennaria ; notwithstanding the capillary pappus of the
sterile flowers; which, although not thickened even in the slight manner of
the preceding species, is yet manifestly barbellate (under a lens) towards the
apex.
