Taxonomy
A solitary, massive, moderately slow growing, monoecious palm with a hapaxanthic or monocarpic mode of growth where the plant dies after setting seed. It has a rough, grey-brown trunk, tall, in diameter with no obvious leaf scars, and massive partially segmented, palmate (fan) leaves, long, wide, dark green above and beneath, on the end of 3 metre (9 feet) long petiole, armed with black teeth. These are one of the largest palmate leaves of any plant. The leaves are circular costapalmate and carried on long stout petioles armed with black teeth. These, together with C. umbraculifera's hold the record of the largest palmate leaves of any plant. The main identification characteristic of C. taliera is that the tree has no persistent leaf-bases when young, unlike other Corypha species which hold huge rhino horn shaped leaf-bases for many years before shedding them to reveal a rough grey trunk.
