Common name:— coco-amargoso, peririma, coco-verde, patioba, palma-blanca, gariroba, guariroba.

Etymology:— The specific epithet, pseudococos , means false coconut and is in reference to the similarity in appearance of this tree to the coconut, according to Raddi.

Distribution and habitat:— Espírito Santo, Rio de Janeiro and São Paulo , Brazil, in the coastal region of the Atlantic forest, generally in rocky soils on steep slopes.

Conservation:— Because of its wide distribution and habitat in rocky soils and steep slopes, this palm is classified as least concern, LC.

Phenology:— Fruits principally during summer (December–March).

Uses:— The mesocarp of the fruit is edible, and so are the seeds. The trunk is utilized locally in rural construction. The palm is ornamental and cultivated occasionally in landscaping.

Notes:— This palm has a very tall, smooth, clean stem, its nut is globose with a very distinctive, broad, conical structure at its apex, resembling a Chinese hat. It also has a fairly thick peduncular bract, similar to S. botryophora .
