St. Diego, California: rare.—About a foot high. Leaves 1—14 inch
long, 2-3 lines wide, white on both sides, with a blackish apiculate point.
Involucre very floccose at the base : perfect flowers about 5.—Allied apparently
to G. lanuginosum; but strongly resembling some species from the
Cape of Good Hope. Nuttall.
* * * Leaves not decurrent: scales of the involucre never yellow: heads racemosespicate.
10. G. purpureum (Linn.) : stems mostly simple or branched from the
base, erect or ascending, tomentose ; leaves oblong-spalulate or oblanceolate,
mostly obtuse, mucronate, tapering to the base, somewhat arenose-woolly,
but green above, densely tomentose and canescent beneath ; heads in sessile
clusters in the axils of the upper leaves, and spicate at the summit of the
stem ; scales of the involucre lanceolate-oblong, scarious, tawny or whitish,
the inner often marked with purple; achenia minutely scabrous.—Linn.!

the Southern States, March to June.—Root apparently annual, at least in the
northern plant; but described as perennial by Muhlenberg, Elliott, Darlington,
&c.; which appears to be the case in some southern forms of this
variable species. Stem 6-20 inches high, slender. All the species of this
subdivision are ill defined.
11. G. uslulatum (Nutt.): perennial, herbaceous, erect, canescently tomentose;
stem simple, terete, floccose-pubescent; leaves oblong-spatulate, obtuse,
mucronulate; the upper ones narrower, sessile (not decurrent); heads
oblong, aggregated in the axils of the upper leaves into a Continuous short
and dense oblong spike; scales of the involucre lanceolate and linear, acute,
brownish towards the points. Nutt, in trans. Amer. phil. soc. 1. c. p. 405.
Plains of the Platte towards the Rocky Mountains, and near St. Barbara,
California, N u tta ll.—Said to be nearly allied to G. spicatum, and therefore
perhaps not distinct from G. purpureum.
12. G. sylvaticum (Linn.) : stem simple, herbaceous, erect, leafy, tomentose;
leaves linear-lanceolate or linear, woolly beneath or on both sides;
heads axillary, sessile [forming a leafy spike]. DC. 1. c.— Wahl. fl. Lapp,

mistaken in giving this species as a native of New York and Canada; in
stony woods.
