Description: |
Large evergreen tree, up to 40 m high, starting as a hemi-epiphytic strangler but eventually free-standing. Stem often with numerous aerial roots eventually forming supporting pillars. Bark fairly smooth, pale to dark grey, sometimes mottled. Leaves thinly leathery and stiff, elliptic or slightly obovate, 5-12 cm long, dull glossy dark-green above, paler beneath, hairless on both surfaces; lateral veins and midrib raised and yellowish above not raised beneath, finer veins indistinct; apex rounded or finely pointed; margin entire; petiole 14-32 mm long, hairless. Fruit sessile, singly or in pairs in the leaf axils, sometimes below the current leaves, mostly globose, 10-15 mm in diameter, hairless, yellowish-green with small warts, bright red or pinkish when ripe; ostiole not or slightly raised. |
Notes: | Similar to Ficus burkei and mainly differing in darker, completely hairless leaves, which are broader, widest in the middle and more rounded at both base and apex. It generally becomes a much larger tree with numerous aerial roots and is more restricted to high rainfall areas of woodland and forest. |
Derivation of specific name: | rokko: a vernacular name used by the Niam-niam in northeastern DRC, where it was first collected. |
Habitat: | In montane evergreen forest, riverine forest and occasionally in high rainfall Brachystegia woodland. |
