According to FloraBase, the terete leaves are 8 to 13 cm long and about 1 mm wide. The leaves have neither bristles nor hairs on the leaf margin nor on the surface of the leaf,[3] but according to Flora of Australia online, the leaves are flat and villous (covered in long soft hairs).[4] There is no scape. The inflorescence is subtended by a bract 10-12 mm long, with one flower. The floral bracts are 10-12 mm long and have sessile pedicels. The radially symmetric flowers are 35-65 mm long, with hairy perianths, are white to cream, with six roughly equal tepals. There are six stamens, all at one level, having filaments which are 7-8 mm long. The anthers have no appendages and are 5.5-5.7 mm long. The style is 25-38 mm long. The plant flowers in July/August.[3]
