BR . 1. Both sides of leaf with pronounced raised honeycomb-like fine reticulum of veins; leaf blades glabrous at maturity; flowers 4-5 mm long .............................................................................................. E. polyneura Schltr. — Leaf surfaces with open, somewhat irregular venation; leaf blades glabrous or pubescent at maturity; flowers up to 3 mm long .............................................................................................................................................. 2 2. Leaf blades 4-5(-6) cm long, usually roundish; petiole up to 6 mm long; mature fruit c. 2.7 cm long; northeast of main island ....................................................................................................... E. poueboensis Guillaumin — Leaf blades, at least the larger ones, more than 6 cm long, petioles, at least the longer ones, more than 8 mm long; fruit more than 3 cm long; variously distributed ................................................................................. 3 3. Petioles up to 1.5 mm wide near midpoint; blades chartaceous; Île Art ..... E. artensis Munzinger & McPherson — Petioles 2-3.5(-4.5) mm wide near midpoint; blades subcoriaceous; main island ……….. 4 4. Young mature blades evenly pubescent abaxially with minute appressed hairs, this indument usually persistent in older leaves at least in sheltered places ..................................................................................................... 5 — Young mature blades glabrous or very nearly so ........................................................................................... 9 5. Abaxial leaf surface often copper- or silver-coloured because of dense, persistent indument obscuring the surface; fruit to 3.8 cm .............................................................................................................. E. sebertii Guillaumin — Abaxial leaf surface usually glaucous, the indument typically not obscuring the surface, either eventually falling or largely persistent; fruit c. 5 cm ................................................................................................................ 6 6. Ovary densely pubescent, as is the fruit in sheltered places; petioles typically less than 2 cm long, widespread on non ultramafic substrates ................................................ E. trichogyna Munzinger & McPherson , sp. nov. — Ovary and fruit glabrous (or very nearly so); petioles various (if less than 2 cm , then restricted to Mt. Humboldt ultramafics) ................................................................................................................................................. 7 7. Leaf blades typically ovate, indument persistent, abaxial surface glaucous; widespread on southern ultramafic substrates ................................................................................................................... E. baillonii Guillaumin — Leaf blades typically elliptical or narrowly elliptical, the abaxial indument eventually falling in exposed areas, abaxial surface not glaucous; Mt. Humboldt or Roches de la Ouaième ........................................................ 8 8. Leaf blades elliptical, petioles 0.7-1.5 cm ; restricted to Mt. Humboldt ........................................................... ........................................................................................ E. humboldtiana Munzinger & McPherson , sp. nov. — Leaf blades narrowly elliptical, petioles 2.0-3.0 cm; restricted to Roches de la Ouaième ....... E . sp. (ouaième) 9. Adaxial surface of midrib and often also the rest of the lamina pimpled due to raised oil glands (most evident in dark-drying areas, using lens) ................................................................................................................ 10 — Adaxial surface, including the midrib, smooth, the oil glands barely evident ............................................. 11 10. Blades (7-) 10-16 cm long; Koniambo c. 700 m ................................................................... E . sp. (koniambo) — Blades 4-10(-11) cm long; widespread but not known from Koniambo .......................................................... .............................................................................. E. lecardii Guillaumin / E. neocaledonica Kosterm. complex 11. Blades 17.5-27.0 cm long .......................................................................................................... E . sp. (taom) — Blades (6.6-)8-9(-9.6) cm long ............................................................................................. E . sp. (fridoline)
