This curious juvenile fig growing in the BORA rhino orchard at Tabin is believed to be Ficus cucurbitina an unusual rare fig of primary forest with very distinctive fig fruit covered in sharp spines. Unfortunately it is too young to fruit at present.
Due to the dense spines covering the young leaves this fig was initially listed at BORA as Ficus consociata but the leaf venation is very different indeed. See this link to Ficus consociata at Maliau.
The leaf size and venation is most similar to Ficus bracteata. However Ficus bracteata may be an invalid name.
