distant pairs, opposite, the upper ones the largest, 3 inches long, all ovate, 
rather acute, flaccid, roughish with pubescence, 3-nerved at the base, 
the margin serrated, the base attenuated into a longish footstalk, which

volucre cylindrical, of 2 green, slightly hispid, erect leaflets, their extre- 
mities patent, acute. lorets few, yellow, each within a chaffy scale, of 
which the outermost ones are large, and like the leaflets of the involucre ; 
the inner ones gradually smaller. -Florets of the ray about 4, semifloscu- 
lose, scarcely longer than the involucres, tube slender, limb ovate, notch-
