Leaves coriaceous, entire, narrowly oblanceolate or elliptic, 8-12 x 2.5-4.5 mm, mostly about 3 times as long as wide, apically acute in general outline but the actual apex obtuse, gradually tapering basally into the petiole, moderately to densely appressed to spreading pubescent with inconspicuous, fine, hyaline trichomes less than 0.1 mm long on both the surfaces, the lower surface also with a sparse scattering of dark clavate glandular fimbriae, dark green above and green below; venation indistinct above and indefinite but pinnately parallel below, the midvein distinctly impressed above and slightly elevated beneath; petioles 1-1.5 mm long, moderately spreading short-pubescent with sordid trichomes, conspicuously glaucous. Inflorescence of solitary, subsessile flowers; pedicels to 1.2 mm long; floral bracts 2-3, oblong to ovate, pale green; bracteoles 2, broadly clasping, ovate, broadly rounded, borne just beneath and embracing the flower, outside moderately to densely spreading fine pubescent, glabrous within.
