Inflorescences produced from topmost c. 3 nodes; inflorescence bracts somewhat inflated, the rachillae few but held rather close together, c. 50 - 70 x 3 - 4 mm, the bracts rather conspicuous, the floral pits with very few hairs. Mature fruit rounded or top-shaped, c. 10 mm diam., with a short beak, and covered in 17 vertical rows of yellow-brown, darker-tipped scales. Seed ovoid c. 8 x 6 mm; endosperm deeply ruminate.
