immersed veins, sessile, some quite entire, some sharply few toothed, 
others (occasionally) “ toothed or cut along their whole margin ;”

Leaves closely set, 14-2 inches long, 2-6 lines wide, cuneate-attenuate at base. 
Pedune. 3-5 inches long, if branched, the pedicels as long. FI. and fruit wanting

from Othonna coronopifolia.
