Illustration above Ficus tengerensis described as Ficus fistulosa in King (1888).
FICUS TENGERENSIS (Miq.) Kuntze (1891) SECTION SYCOCARPUS
Latin: From Tengger a volcanic mountain in east Java, part of the Tengger-Bromo-Semeru National Park.
Habit: Uncommon small tree in hill forest throughout Borneo. There are records from Kubah near Kuching but no records from Kalimantan where it almost certainly occurs.
Leaf: Consistently and distinctively smaller and thicker than the leaves of Ficus fistulosa.
Fig Fruit: The small figs with curved peduncles hang from the trunk (cauliflorus) or from the branches (ramiflorus). The fig fruit are consistently smaller with relatively longer peduncles than the fig fruits of Ficus fistulosa.
(1) Ficus fistulosa : See differences listed above
(2) Ficus globosa fig fruits grow in the leaf axils at the end of the twigs and are never cauliflorous or ramiflorus.
Range: Borneo, Java, Malay Peninsula, Thailand.
Taxonomy: Considered by many authors including King (1888), and Berg (2005) to be variety of Ficus fistulosa. However both species occur together in the same area and are consistently distinguishable by the smaller thicker leaves and smaller figs of Ficus tengerensis.
