-A . BUND ANT every where in dry paftures, wafle ground,
and by road tides, flowering copioufly in the ufual hot weather
of July and Auguft, at which time it forms a contrail with the
furrounding fcorched and withered herbage.
Root perennial. Stem eredt, furrowed, very leafy, branched
in a corymbofe manner. Leaves alternate, deep Ihining.green,
doubly pinnatifid, or cut into various fpreading, wedge-fliaped,
toothed fegments : the lower ones on (talks ; the reft embracing
the Item. Flowers very numerous, in terminal upright
corymbi, of a bright golden yellow, efpecially their radius,
which confifts of a great number o f linear narrow florets, at
firft fpreading, but recurved in decay. The feeds of the dilk
are thickly clothed with Abort lilky hairs, but I am obliged to
Mr. Sowerby for obferving that thofe of the radius are quite
fmooth. The down of all is rough, but not feathery. A
cottony web, more or lefs denfe, frequently invefts the flower-
llalks and calyx.
In Yorklhire this plant is fometimes called Swine’s Crefles,
and has been recommended in a bruifed ftate as an application
to cancers.
The leaves are devoured by the pretty black and yellow
ringed caterpillars of the Pbalcena Jacob a a.
