Diagnostics:

Mangifera caesia is a large tree up to 35m (Ding Hou, 1978), with near obovate leaves and a thick, raised mid vein. Not sure if this is a characteristic trait, but pine nuts-like structures are present at the terminal of the branches . Only this mango species in Malaya (which includes Singapore) have lavender coloured flowers (Corner, 1997).


Interesting Facts:

Binjai used to be planted in the past by kampongs for their sour tasting fruits (NParks, 2009). A number of large mature Binjai still exist and are designated as heritage trees. Corner (1997) warned that of the irritable sap of mangoes, and citied Binjai as one of the most poisonous.
