Ficus septica, collected by Elmer in the Philippines from the Leiden Herbarium. The majority of Borneo’s figs originated in the area known as Sundaland including the Malay Peninsula, Sumatra, Java, Palawan and Borneo. Most of Sundaland is now drowned under the South China Sea.
Ficus septica is one of several figs which have invaded Borneo by crossing Wallace’s Line from east to west. Other east to west invaders include F. forstenii, F. gul, F.lawesii, F. glandifera, F.cuminigii, and F. minahassae.
