Plant acaulescent, up to 32 cm tall, the leaves at the apex spreading to about 18 cm diam., proliferous from the base and forming clumps of about 2-6 plants. Leaves about 24, ascending (in the clumps the leaves on each plant are bent away from one another), firm, up to 30 cm long, up to 28 mm broad at the base, 4 mm thick at middle of leaf, lanceolate, acuminate-subulate; face concave, smooth, with a raised concolorous line in the lower 3/4, and beset with few to many inconspicuous, small, whitish round tubercles, the old leaves bright light green towards the apex, darker dull green below, the young light green towards the apex, light bluish green below; back convex, pale green towards the apex, darker green below, beset with many round and oblong bluish-white, up to 1.75 mm diam. tubercles on some plants, to about 0.5 mm diam. on others, many of the tubercles confluent, in some cases in all directions, in others forming irregular transverse bands, the tubercles very conspicuous in the lower 2/3 of leaf, less conspicuous above due to the lighter green colour of this part of the leaf, obliquely keeled from near the base to the tip, margins acute. Peduncle simple, +/-terete, 2.5 mm diam., including the raceme up to 60 cm long, very pale green below, becoming light glaucous green above; raceme up to 12 cm long, about 40 spirally arranged flowers and buds, 2-4 open simultaneously; pedicels 3.5 mm long, 1 mm diam., erect, light glaucous green; sterile bracts 4-6, the lowest about 26 cm from base of peduncle, 8.5 mm long including the awn; fertile bracts 5.5 mm long, deltoid-lanceolate, subulate, white with a nerve which is bright green and broad below, becoming greenish-brown and fine above; perianth white, greenish nerved, 17.5 mm long, the cylindrical-hexagonal sub-globose base 4 mm diam., and tapering to the pedicel, constricted to 3.5 mm above, oblong, ascending, curved; upper segments channelled, the 2 outer obtuse, very recurved, face colour white with a broad green nerve, the inner segment narrow obtuse, less recurved, face colour white at tip, light green below, with a broad very green nerve; lower segments obtuse, channelled, the 2 outer very recurved, replicate, face colour white at tip, light green below, with a medium broad very green nerve, the inner segment revolute, face colour white with a medium broad green nerve; stamens 7 and 5.5 mm long; ovary 3.5 mm long, 1.5 mm diam., ovate, bright green; style 1.25 mm long, green, with whitish tip, straight, not capitate.
