blade base

The earth-crushing weed-breaking pulping device is fixed on each blade base through a bolt which is used for fixing a rotary coulter.

Leaf blade base cuneate or rounded, abaxial indumentum yellowish brown or brownish; corolla white to pinkish, with deep red lines.

Leaf blade base rounded, abaxially villous to glabrescent, hairs brownish or yellowish; calyx without blotches, orifice nearly orbicular.

Leaf blade base cordate, abaxial indumentum olivaceous or brownish; corolla yellow or white, with red spots.

leaflet blade base usually oblique, margin usually entire, very rarely serrulate.

Leaf blade base usually attenuate; male flower with adaxial gland ca. as long as bracts, abaxial gland absent.

since a winged petiole is really a decurrent leaf blade, they are described here as the leaf blade base.
