SWAMP FIG Ficus acamptophylla    Miq. (1867)  SECTION: CONOSYCEAE

Greek: Stiff leaves.

Plant: Climber usually epiphytic sometimes at ground level scrambling over shrubs or bushes usually confined to freshwater swamp forest in coastal districts, occasionally elsewhere.

Leaf: Large oval to oblong leaf, 4-12cm long x 1.8-6cm wide with a petiole (leaf stalk) up to 1.5cm long. The leaves are stiff and revolute with the edges of the leaves turned inwards.

Fig: Small fig 0.8-1cm, sessile (no stalk) in pairs in the leaf axils but often on the bare branches behind the leaves. The figs ripen green to orange to red.

Sex: Monoecious.

Similar species: Ficus soepadmoi (probably con-specific) is a very rare coastal fig likely to be found in similar locations and with similar looking figs.  Ficus paracamptophylla has similar looking oblong leaves but Ficus paracamptophylla has very strong distinct basal veins absent from F. acamptphylla, as well as persistent bracts around the terminal leaflets of each branch .See also the article on F. palungensis.

Distribution: A common fig of coastal and swampy areas especially abundant around Kuching. According to Corner (1975)  F. accamptophylla may festoon tall trees along the smaller rocky rivers of Sarawak and Brunei.

Sabah: Kimanis FR, Labuk Rd (Sandakan), Gng Silam.

Brunei:  Andulau FR, Labi FR. Kalimantan: Ketapang, Sampit, Rantau (Kalsel) Sg Wain (Kaltim) around reservoir lake.

Sarawak: Bako, Semengoh, Santubong. The 17th commonest fig at Lambir with 18 individuals in the 52 ha plot (Harrison).

Range: Confined to the coastal areas of Borneo especially common in south and western Borneo. Also in a small area of S.E.Sumatra, including Pulau Banka where it is rare.

Notes: Rhett Harrison (2006)  studied Ficus acamptophylla at  Lambir National park in N.Sarawak. F. acapmptophylla was  previously common in the freshwater peat swamp forest that surrounded  the dipterocarp forest on Bukit Lambir. When the peat swamp forest was converted to agriculture one remnant isolated F.acamptophylla was left growing next to the Lambir lab building. With the loss  of the surrounding F. acamptophylla figs this isolated individual could no longer be pollinated and all the figs produced were sterile.
