Stem 3 mm. or more diam., mostly hidden by ± horizontal lvs. Lamina subcoriac., spathulate to suborbicular, narrowing gradually to short broad petiole; margins regularly finely crenate; upper surface and margins densely clad in long tapering hairs, undersurface glab. to variously hairy. Peduncle erect, hairy, often without cauline lvs below floral bracts. Bracts us. in pairs, oblong-spathulate, ± crenate near obtuse apex, both surfaces us. hairy. Pedicels c. ═ corolla in fl., elongating in fr., densely clad in multicellular hairs. Calyx unevenly divided; lobes broad, entire, obtuse to truncate, with hairs as on pedicel. Corolla glab. outside.
