A very pretty variety of durian with a particularly mild odor, sometimes even described as odorless, which is oddly contradictory given that graveolens translates to ''strong smelling.'' Its origin is still a bit of a mystery as there are other durian sold under the names 'red flesh' or 'red prawn' though those belong to the durio zibethinus species, which is the most common durian variety most people are familiar with. Dugyan tends to come in three colours, in terms of flesh, hence the common names, but it's still unclear whether these are differing species. There has been a lot of back-and-forth over the years, grouping the species together with others, reducing it to a synonym for existing species and then separating it again as a species of its own. You'd think with all that effort going into its classification, this fruit has to be something really special, but taste-wise it has been described as bland, even flavorless and compared to eating an avocado.
