Common madia is a strongly-scented, simple to
branched annual to 32" tall, very glandular and sticky in the upper
part of the stem and villous below. The leaves are alternate,
linear to widely lanceolate, and entire to somewhat toothed. There
are few basal leaves in a small rosette, and the lower cauline leaves
are crowded, sessile, and densely villous. The upper leaves are
spaced farther apart, much reduced in size and linear, almost bractlike.
The radiate flowering heads are solitary on long stems, and are
both terminal and in the leaf axils. The involucres are campanulate
to hemispheric, and the phyllaries are ± bristly. The heads
are very showy and contain from 8 to 16 yellow ray flowers that sometimes
have a maroon blotch at the base, and 25-50+ staminate disk flowers
that are yellow to maroon with purple-black anthers and no pappus. The
ray achenes are flattened, black to dark-brown and glabrous. Common
madia is quite abundant on dryish chaparral slopes and grassy meadows
from 3000' to 8000', and ranges from San Diego Co. to Oregon, blooming
from June to August. The first picture was taken in Rocky Oaks Park
in the Santa Monica Mountains, and the other two in the San Bernardino
Mts. All the former subspecies of Madia elegans have now been consolidated under this single name.
