Key to the species of Kermadecia

1. Flowers sessile, paired, each pair on a short peduncle (to 2 mm long), peduncles arranged along the length of an otherwise unbranched inflorescence axis .. K. pronyensis

1a. Flowers pedicellate (pedicels 8 –16 mm long), arranged in collateral pairs along the length of a branched or unbranched inflorescence axis ..................................... 2

2. Abaxial surface of adult leaves densely covered by a ferruginous indumentum of minute hairs; inflorescence axes robust (≥ 7 mm diam. near the base) ............. K. sinuata

2a. Abaxial surface of adult leaves glabrous or almost so; inflorescence axis less robust (3–4 mm diam. near the base) ............................................................................ 3

3. Adult leaves with secondary and tertiary venation sharply raised on abaxial surface of blades; base of blades cordate ....................................................... K. brinoniae

3a. Adult leaves with secondary and tertiary venation slightly raised on abaxial surface of blades; base of blades obtuse, rounded or slightly cordate (rarely markedly cordate) ...4

4. Main inflorescence axis unbranched ............. K. elliptica

4a. Main inflorescence axis commonly with 2 – 4 side branches ................................................ K. rotundifolia
