AND GENERA OF PLANTS. 317 
Chrysopsis pilosa, ©; very softly pubescent and hairy; leaves elongated, 
linear-lanceolate, acute, the lower ones incisely serrate, scales of the involu- 
crum linear-lanceolate, acuminate, nearly equal; achenium with ten ribs; (a 
character common to the fruit of other species of Chrysopsis when perfectly 
mature.) C. pilosa, Nutt., Journ. Acad. Nat. Sci. Philad., Vor Vil, p. 66. 
(Small oe in which the leaves often occur entire.) ; 
Subgenus. —*PHYLLOTHECA. Rays feminine, with rudiments of stamina or fila- 
ments. Stigmas of the ray very long, filiform, and smooth, those of the disk 
pubescent at the apex, and somewhat lanceolate. External paleaceous pappus — 
minute, the inner pilose and scabrous; involucrum imbricate, and bracteolate or 
‘foliaceous. 
Chrysopsis we Ata %; viscid and pubescent, Lanta oblong acute, en- 
tire, sessile; brant hes fastigiate, w with o1 one to three sessile “capituli. 
Has. St. Barbers, ropes California, Flo in. a heavy aromatic odour 
and bitter taste, almost like that of some Gnaphaliume. The whole plant more or less hirsute 
and viscidly glandular; leaves about an inch long, three or four lines wide, linear-oblong, rather 
te 
crowded, narrowed below, sessile. ‘The capitulum surrounded by leaves at its base, like those of 
the stem, only narrower and longer. ‘The outer pappus scarcely visible. Rays narrow and elon- 
gated, deeply toothed, about thirty. 
* PITYOPSIS.+ 
Flowers heterogamous, rays feminine; florets of the disk five-toothed, tubular. 
Stigmas slenderly filiform, equal and obtuse, in the ray smooth, in the disk 
hirsute. Receptacle alveolate, dentate, naked. Involucrum imbricated in 
several unequal series; scales carinate, rigid, membranaceous on the margin. 
Achenium slender, cylindric-fusiform, internally angular, even, and ten-stri- 
ate, contracted and rostrate at the summit, acuminate below; pappus double, 
each in a single series, the external short, slender and paleaceous, the inner 
pilose and scarcely scabrous, (of forty to forty-five rays.)—Perennials, with 
alternate, entire, filiform or rear 3 leaves, naked, or more psoas clothed 
é 
t P. pinifolia having leaves resembling those of the pine tree, and hence the allusion.
