Durio dulcis is one of the rarest durian species. With it's bright red shell, it's the sweetest of the durians (as suggested by it's Latin name) but isn't cultivated and is only found in the highland jungles of interior Borneo, where it is becoming increasingly more scarce due to illegal logging. It's even listed on the IUCN Red List of threatened species.
We were actually on the hunt for a different rare durian, the kura kura, or tortoise durian (durio testudinarum) which grows fruit on the roots and trunk of the tree instead of the branches. But when stumbling upon rare and delicious durians, who's going to complain? We were having bum luck anyway - KOMPAKH really and truly is the only resource in Putussibau for tourists and all their guides were out of town. Then we bumped into Linda, a part time English teacher at the high school, who thought we might score some neat durian near an Iban longhouse along the road to Lanjak. She was right! Not only did we spend our Thanksgiving eating the sweetest durian of them all, we had a pretty amazing cultural experience.
