AND GENERA OF PLANTS. 389 
2 sete feet high; the flowers racemose, and in strong plants corymbose or with fastigiate few-flowered 
"branches. Involucrum that of madaria; rays shorter, deep yellow, rather showy. Achenium 
black ‘and smooth, similar to that of Madaria, but without angles. Pappus of the central florets 
almost like that of Bahia, obtuse and fringed. 
*HARPAECARPUS. 
Capitulum many-flowered, radiate; rays feminine, in a single series, about five 
to eight, truncated, very short, and two-lobed, scarcely as long as the filiform 
style. Discal floret one! tubular, five-toothed, hermaphrodite, fertile. Style 
scarcely exserted, short, nearly smooth, and somewhat obtuse. Involucrum 
spherical, five to eight-leaved, the sepals carinate, closely investing the ache- 
nium, and falling off in connexion with the mature fruit. Receptacle very 
narrow, containing within the ray a foliaceous, pubescent, and glandular 
involucrum of five wholly united leaves, surrounding the single hermaphro- 
dite floret! Achenium of the ray compressed, smooth, falcate and granu- 
lated, produced at the base and summit; central achenium nearly straight 
and somewhat angular, naked.—Hirsute annuals of Oregon. Stem simple, 
corymbosely paniculate. Capituli long pedicellate, glandular; flowers mi- 
nute, yellow. Leaves linear, entire, the lower ones opposite. A very dis- 
tinct genus, though still closely allied to Madia; but the falcate achenia fall 
off invested by the deciduous sepals; and the only hermaphrodite central 
floret, like a true proliferous flower, is entirely separated by an involucrum 
"similar to that of the ray, and united into an entire, five-toothed cup. The 
whole plant of an aromatic odour—(The name from ‘apo, @ sickle, and 
xapttos, fruit; in allusion to the form of the fruit.) 
Harpecarpus Madarioides. 
Has. On Rocky plains in depressions, at the outlet of the Wahlamet. Common ; flowering in 
May. From a few inches to two feet high. Hirsute with rather long hairs. Leaves about a 
line wide, one to two inches long, acute, entire, except the radical ones, which are sometimes 
slightly denticnlate. Capitulum glandular, depressed spherical, somewhat smaller than a grain of 
Pedicels various, in the fruiting state two to three inches long, in other smaller 
specimens the flowers are nearly sessile, except the terminal ones. Flowérs pale yellow.
