Ficus annulata growing at Sg Mokodou, Kg Nalumad, Ranau district, Sabah. The orange arrows point to the peduncles or fruit stalks on the figs. Ficus annulata is very variable and some plants may have figs with peduncles and on other plants the figs may be sessile, – i.e. without peduncles.

The orange arrow shows how the peduncle of Ficus annulata has a ” tap root” which extends well into the body of the fig.

As far as is known no other Bornean fig including the very closely related Ficus depressa has a peduncle with a root.
BLACK ARROW: Points to the root of the peduncle
GREEN ARROWS: Point to damage on the wall of the fig caused by NPFW (non-pollinating fig wasp) parasites. NPFW drill into the fig with their long ovipositor or egg laying tube so that they can lay eggs inside the ovaries replacing any seeds that might be developing.
BLUE ARROW: Ostiole. The entrance to the interior of the fig blocked by bracts which act as a one way gate, allowing pollinating fig wasps in but not out and blocking the entry of all NPFW.
