The flowers are small, yellowish, produced on a Template:Convert inflorescence. The fruit is an edible 1 cm drupe resembling a small, thin-fleshed date.[5]
This Palm produces strong, spiny thorns approx. 2-4" in length. The size of the thorns depends on the age of the tree. These thorns are located on the Palm Leaf stem close to the trunk and can extend 6-12". The thorns are very sharp and easily penetrate the skin. They are poisonous and can cause irritation, skin infection, bruising and can be severe. They can also cause an allergic reaction. These reactions differentiate on the exposure.Script error: No such module "Unsubst".
