Family: Anacardiaceae

Origin, Description & Uses
Mangifera casturi (Kalimantan mango or kasturi) is a small to medium-sized tropical fruit tree native to southern Borneo (Kalimantan), Indonesia, particularly around the Banjarmasin region. It is closely related to the common mango (Mangifera indica) and produces fragrant, flavorful fruits that are highly prized locally. The tree has glossy evergreen leaves and a dense canopy, making it both an attractive landscape tree and a source of shade in tropical gardens. Its fruit is typically small to medium in size, with a sweet, aromatic flesh that is eaten fresh or used in local foods and beverages.

Risks & Threats
There are no known records of Mangifera casturi becoming naturalized or invasive in Hawai‘i or other non-native regions. It is generally considered a low-risk species, especially when compared to more aggressive members of the mango genus. However, as with many fruit trees introduced outside their native range, there is always some uncertainty about long-term behavior in new environments. Continued observation is still useful to ensure it does not spread beyond cultivation or compete with native vegetation.

High Risk Traits:

• Thrives in tropical climates
  
• Self-compatible
  
• Fleshy fruited, and seeds may possibly be dispersed by birds and mammals

Low Risk Traits:

• No reports of naturalization or invasiveness of this species
  
• Unarmed
  
• Produces edible fruit
  
• Reaches maturity in 4+ years
  
• Does not spread vegetatively
  
• Large fruit and seeds unlikely to be inadvertently dispersed
