A clump-forming, small, water-loving, moderately fast growing, monoecious, forest understorey palm. Not known in cultivation, scarce in the wild. It has smooth, green stems, 1.8 m. (6 ft.) tall, 0.7 cm. (0.3 inch) diameter with spaced ring leaf scars, and small segmented, pinnate (feather) leaves, 0.2 m. (0.6 ft.) long, 0.2 m. (0.8 ft.) wide, green above and beneath.

This plant is suitable as a houseplant or conservatory plant.

Geonoma aspidiifolia subsp. aspidiifolia naturally occurs in wet and humid tropical rainforest. 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, and is one the most difficult palms to keep in cultivation.
