Family: Arecaceae

Origin, Description & Uses:
Iguanura bicornis, commonly known as horned seed palm or iguanura, is a small, understory palm native to the tropical rainforests of Southeast Asia. It typically grows as a clustering palm with slender stems and graceful, pinnate leaves that give it an elegant, compact appearance well suited for shaded landscapes. This species is especially valued as an ornamental for gardens and indoor plantings in humid climates, where its manageable size and attractive foliage make it a popular choice for adding a lush, tropical aesthetic. Its tolerance for low light and preference for moist, well-drained soils further enhance its appeal for cultivation.

Risks & Threats:
This species is considered low risk and is not known to naturalize or become invasive in Hawaiʻi or similar tropical environments. Iguanura bicornis generally lacks aggressive growth traits, does not spread rapidly, and relies on specific rainforest conditions that limit its ability to establish outside cultivation. There are no significant reports of ecological harm, displacement of native species, or impacts to ecosystem processes associated with this palm. As a result, it is regarded as a safe choice for landscaping, though, as with all non-native plants, responsible planting and monitoring are still recommended to prevent any unforeseen spread.

High Risk Traits:

• Thrives in tropical climates
  
• Shade-tolerant
  
• Fleshy-fruited plant may be dispersed by birds or other animals
  
• Rare in cultivation. Ecology of species poorly understood

Low Risk Traits:

• No reports of naturalization or invasiveness found for this or any other species in the genus
  
• Unarmed (no spines, thorns or burrs)
  
• Non-toxic
  
• Landscaping and ornamental value
  
• Relatively large fruits and seeds unlikely to be inadvertently dispersed
