A solitary, smallish, water-loving, salt-tolerant, moderately fast growing, monoecious, forest understorey, crownshaft palm. Not known in cultivation, vulnerable in the wild. It has a smooth, greenish waxy trunk, 4.9 m. (16 ft.) tall, 20 cm. (8 inch) diameter with spaced ring leaf scars, and large segmented, pinnate (feather) leaves, 2.1 m. (7 ft.) long, 0.9 m. (3 ft.) wide, dark green above and beneath.

This plant is suitable, while young as a houseplant or conservatory plant.

Pinanga tashiroi naturally occurs on islands in moist forest, and is heavily effected by the surrounding sea temperatures, which are constant and often form sea mist and cloud. In this type of natural environment temperature fluctuations are slight, and this palm prefers a constantly hot and humid climate with little temperature difference between day & night, and Summer & Winter. This palm will not tolerate cool for very long.
