Leaf-blades filiform; conduplicate; elliptic in section; 0.6-1.1 mm wide; without exudate, or pruinose. Leaf-blade venation comprising 7 vascular bundles; with 5-7 inner ridges; with 3 subepidermal sclerenchyma strands; with subepidermal sclerenchyma free from veins; without layer of subepidermal sclerenchyma masking vein striation, or with sclerenchyma strands widened to form a discontinuous subepidermal layer, or with unevenly thickened subepidermal sclerenchyma layer on the underside. Leaf-blade surface scabrous; glabrous, or pubescent; hairy on both sides.
