4 mm diam., with sheaths to
6 mm diam., internodes c.
12 cm long. Sheaths dull greenish-brown, unarmed; knee present, rather small; ocrea short, tubular,

40 cm; petiole very short or absent; rachis covered in dark brown hairs; leaflets c.
7 on each side of the rachis, rather broad lanceolate with
3 conspicuous veins, the terminal leaflet pair joined for about
21 3 their length, the others
± regular, alternate, the mid leaflets c.
