Stems dark brown, superficial cortical layer with spiral reinforcing fibrils visible, usually 2 or more pores per cell, comb-fibrils lacking on interior wall. Stem leaves to 1.2 × 0.8 mm; rarely hemiisophyllous; hyaline cells mostly nonseptate, comb-lamellae usually absent, but sometimes weak. Branches short and blunt-tipped, leaves spreading. Branch fascicles with 2 spreading and 1 pendent branch. Branch stems with hyaline cells non-ornamented, no or weak funnel-like projections on the end walls of cortical cells, cortical cell walls usually with large round pores. Branch leaves ovate to ovate-elliptical, 1.6-2.2 × 1 mm; hyaline cells on proximal half of convex surface with round to elliptic pores along the commissures; comb-lamellae on hyaline cell wall where overlying chlorophyllous cells; chlorophyllous cells broadly triangular in transverse section and well-enclosed on convex surface, end wall not thickened.
