What is "trithrinax"

Trithrinax is a genus of few flowering plants in the Arecaceae family, that belong to the Coryphoideae subfamily, a not very evolved lineage. The name is derived of ancient Greek, where tri means three, and thrinax trident. It was named as such in 1837 by Carl Friedrich Philipp von Martius a German botanist and explorer.

Trithrinax species are quite spiny fan palms native to South America. They are also resistant to cold, heat, wind, drought, poor soils and other adverse environmental conditions. They germinate fast but their growth is distinctively slow.
