90 Rudbeckia triloba.
1 y three-nerved, hairy on each side, and ciliated on the margin, the
cilise longest towards the base. Stem and branches cylindrical, finely
lined, generally greenish on one side and purplish-red on the
other, or entirely dull-lake-red. Flowers small. Calicine leaves
linear, nearly or often quite as long as the rays, acuminated, and
hairy. Rays emarginated, lanceolate, elliptical, gamboge-yellow.
Disk auricula-purple. Scales of the receptacle awned. Flowers
in August and September. “ In the mountains of Virginia and Carolina.”
Pursh. “ In the New England states.” Eaton.
Another species of the beautiful autumnal genus Rudbeckia, already
fully described in preceding pages, is here figured. It is
rare in Pennsylvania, though sufficiently common to the south
and westward of this state. The flowers of this, are smaller
than those of the other species, none being found much larger than
the drawing represents. For the specimens from which it was
made, I am indebted to Mr. Nuttall, who raised plants of it last summer
in this city.
The plate represents an upper portion with one of the three-lobed
leaves, in its natural situation—the size of nature.
