twigs glabrous, hairy at the base of the petiole; leaves ovate-oblong, or oblong, acute, glabrous above, beneath at the keel and margin ciliato-pilose, gibbous at tip; flowers capitate; peduncles shorter than the calyx; calyx-lobes oblong-lanceolate, with naked margins; petals twice as long as the calyx, with villous claws; sterile filaments dilated upwards, petaloid, with villous, filiform bases, and connate with the claws of the petals. A robust, much branched shrub, with branches and twigs aggregate-umbellate, short, pale. Leaves 2–3 lines long, 1 line wide, densely sub-imbricate, erect, channelled above towards the point, beneath keeled with a raised nerve and furnished with a thick gibbosity at the apex, flat at the margin and ciliate with long white hairs; petiole very short. Heads densely flowered, 4–6 lines in diameter. Floral leaves equal to the others, shorter than the flowers. Peduncles glabrous, with ciliate, linear bracts at point. Calyx 5-parted, the lobe nearly 1 1/2 lines long. Limb of the petals oblong, obtuse, 1 line long, white; the claw twice as long, carrying the sterile filaments in the middle. Fert. filaments longer than the petals, pilose; sterile linear-oblong, gland-bearing below the point, shorter. Style equalling the petals, glabrous. Capsule 2 lines long; carpels 2–3, glandular at back, with a straight horn.
