KALIMANTAN FIG Ficus kalimantana C.C.Berg (2010)
Latin: Named after Kalimantan, the Indonesian name for Borneo.
Habit: Small tree to 6 meters.
Leaves: Small oblong leaves that grow in a single plane (distichous) 2.5-9cm long by 1-3 cm wide. Note that these leaves are around half the size of any similar species. Petiole under 0.5 cm long. 5-7 pairs of lateral (side) veins.
Figs: Small to 1.5cm ripening greenish yellow. Cauliferous hanging from small branchlets growing out of the trunk. The peaked rosette of bracts surrounding the ostiole are exactly similar to those of Ficus rosulata a common bat fig of lowland forest throughout Borneo. However, there are “lateral bracts” small triangular mounds or flaps on the side of the fig fruit- which are absent in F. rosulata
Similar Species: Ficus rosulata.
Distinguish: From F. rosulata by
(1) The presence of lateral bracts on the fig fruit, absent in F. rosulata.
(2) Much smaller leaves and shorter leaf stalk (petiole) which for F. rosulata is 0.5 to 2.5 cm long.
(3) Less lateral veins on the leaf – 5-7 compared with 6-12 pairs for F.rosulata.
Distribution: A very rare Borneo endemic fig with only one record from the hills of West Kalimantan growing next to the Sungai Jelundung south of Nanga Jelundung, Serawai.
