Diagnostic Description

The affinity is with N. fragarioides from which it is distinguished by much smaller differently shaped hairy calyx-lobes, much smaller floral parts, and by the almost total absence of hairs from the top of the ovary.

    About 60 cm high, with pilose branchlets. Leaves mostly 4-5 mm long, at first imbricate, becoming separated, ascending, slightly incurved, sessile, lanceolate, acute, convex and bluntly keeled on the dorsal surface, flat and with a narrow keel on the ventral surface, at first with a tuft of hairs at the apex and ciliate. Flower-heads 5-6 mm long (excluding stamens), obconic, involucred by many scale-like oblanceolate ciliate leaves, apparently axillary, crowded in globose masses 1-1.5 cm long: receptacle densely villous. Bract 4 mm long, oblanceolate, subacute, tapered at the base, bluntly keeled on the dorsal surface, ciliate. Bracteoles 3 mm long, resembling the bract, occasionally sparsely villous on the upper half of the dorsal surface. Calyx-lobes about 2 mm long, linear-oblong in the upper half, narrowing considerably to the base, subacute, villous on the dorsal surface and occasionally also on the upper half of the ventral surface. Petals about 3 mm long, narrowly linear, obtuse, slightly narrowed downwards from shortly below the middle, membranous. Filaments slender: anthers 1-25 mm long, oblong. Ovary 2/3 inferior, minutely pubescent on the summit; ovules attached to about the middle of the dissepiment: styles slightly connate in the lower half. Seeds about 2 mm long, with a ridge within the ventral furrow.
