Urtica sykesii is a many branched herb sparsely clad in stinging hairs which are most numerous on the leaf stalks (petioles) and less so on the leaf blade and plant stem. Flowers are very small and are compactly arranged on branching spikes at the base of leaves. Formerly Urtica incisa.
Found in moist sheltered lowland forest margins and at higher elevations throughout New Zealand.
