Durio kinabaluensis, also known as mountain durian and (locally) as durian tapuloh, is a forest tree in the mallow family. [1] [2]
The tree grows to 40 m in height with a 10–15 m buttressed bole. The oval leaves are 10–16 cm long by 4–6 cm wide, with smooth uppersides, and with undersides covered with golden-brown scales and hairs. The inflorescences comprise clusters of 5–6 pink to reddish flowers along the branches. The greenish-yellow to yellow fruits are 8–10 cm in diameter, covered with small conical spines and containing 3 cm-long brown seeds encased in an edible, cream to pale yellow aril.[2]
The species is endemic to Borneo; its range is restricted to the Crocker Range and Mount Kinabalu in Sabah, where it is found in hill forest and lower mountain forest at an elevation of 800–1300 m.[2]
The species is sometimes planted in the vicinity of villages in the Crocker Range, with the fruits sold at roadside stalls.[2]
