The coconut (Cocos nucifera) is a member of the palm tree family, Arecaceae. Originally native to the Central Indo-Pacific, in the regions of Maritime Southeast Asia and Melanesia, coconuts are now found across the world due to human cultivation and dispersal.

Aerial roots can be co-opted for defense. The trunk of the Mauritiella armata is covered with short, pointed adventitious root-spines. The species epithet is spot-on: This palm is armed. #Arecaceae #root #Botany 🌾🧪🌱

In many Monocots, nectar is produced by septal nectaries, i.e., nectaries in the septa (walls) between the carpels. Female flowers of Chrysalidocarpus lanceolatus have 3 carpels per pistil, so flowers copiously produce 3 droplets in each flower. #Arecaceae #nectary #Botany 🌾🧪🌱
