Leaves sessile; lamina 20-60 x 11-29 mm, ovate or elliptic to oblong-elliptic, subacute to rounded, margin plane, base cuneate to rounded, paler beneath, not glaucous, subcoriaceous, lower ones tardily deciduous; venation: 1-2 pairs main laterals (the upper forming intramarginal vein) and 7 pinnate midrib branches, with tertiary reticulum very faint or invisible; laminar gland dots prominent; intramarginal glands dense. Inflorescence 1-3-flowered, terminal, and 1-2-flowered on subsidiary branches from up to 7(-10) nodes below; pedicel 5-10 mm long; bracteoles narrowly elliptic, subpersistent . Flowers 25-35 mm in diam., stellate to very shallowly cyathiform; buds ± broadly ovoid, subacute to obtuse. Sepals 7-10 x 1.5-6 mm, very slightly connate, imbricate, subequal to unequal, erect in bud, ascending in fruit, lanceolate or narrowly elliptic to oblanceolate or elliptic- ovate, acute to subacute, 5-7-veined with veins reticulately branched, midrib distinct but narrow; laminar glands linear and punctiform; inframarginal glands scattered, indistinct.
