Today, we would like to show you the Common Star-chestnut (Sterculia rogersii). You can find this specific tree on the footpath up to the vulture restaurant, about a 30 minutes walk from Duna.


The common star-chestnut is an unusual looking tree; making it hard to miss with its fat trunk that resembles molten material both in shape and in its grey-pink colour.



The term "star-chestnut" originates from the fruit's unique characteristics, which include three to five fuzzy, boat-like carpels arranged in a star-like formation. Each of these carpels is soft and approximately 5 cm in length, featuring a noticeable beak. They open up to expose black seeds surrounded by slender, delicate hairs. While the seeds are consumable, it is important to avoid touching the stinging hairs, which can cause irritation similar to the bristles on a hairy caterpillar when they come into contact with the skin.
