3. P. pygmea, A. Gray in Hook. Kew Journ. iv. 227. A little annual, 
not 2 in. high in our specimens. Leaves linear, glabrous. Involucre cylin- 
drical or conical, but only about 4 in. long and nearly 3 lines diameter at the 
base, the outer bracts broadly lanceolate and not so acute as in the preceding 
species, thus connecting them with the following ones. Florets slender, 
scarcely exceeding the involucre. Pappus-bristles few, plumose, free or slightly 
united at the base.

4. P. chrysantha, Benth. An erect annual, simple or slightly branched, . 
glabrous or scabrous-pubescent, rarely above 1 ft. high. Leaves linear. Pe- 
duncles rather long, dilated and hollow under the head. Involuere broadly 
turbinate-campanulate, 6 to 8 lines long, the bracts thinly herbaceous, broadly 
lanceolate or ovate-lanceolate, not numerous, and only 2 3 outer ones 
shorter than the others, the innermost linear and scarious. Florets numerous, 
exceeding the involucre. Achenes hairy. Pappus of 8 to 10 barbellate, 
but scarcely plumose bristles.—Jzriolena chrysantha, Steetz in Pl. Preiss. 1.459.

the flower-head. Involucre campanulate, about, 4 in. diameter, the bracts 
not numerous, of nearly equal length, the outer ones herbaceous though thin, 
the inner more scarious, with small scarious tips. Florets slender, all herma- 
phrodite, but the inner ones often sterile, their stalks rather more prominent 
than those of the outer florets, and irregularly cohering so as to give the rè- 
ceptacle almost a conical form. Achenes, when perfect, densely villous. 
Pappus of 10 to 15 rigid bristles, plumose especially at the base, less T 
towards the end.— Helipterum fuscescens, Turcz. in Bull. Mosc. 1851, 1. 80;

Lophoclinium album, Yndl. in Bot. Zeit. 1843, 457, may very probably be this species-

(Scalia, Sims; Panætia, Cass.; Scaliopsis, Walp. ; Siemssenia, Steetz ; Stylolepis, Tini

Involuere hemispherical or rarely ovoid, the bracts imbricate, in gii 
YOWS, with very thin scarious laminz, not radiating, the outer ones sessue, 
irregular. very short.
