General Information

Astrocaryum macrocalyx is an evergreen, single-stemmed palm with a stem around 2 - 10 metres tall and 18-20cm in diameter. It produces a crown of usually 8 - 16 spiny leaves that can be up to 7 metres long including the petiole[].
The plant is harvested from the wild for local use as a food. The fruit is occasionally sold in local markets[]. This presumably refers to the unripe fruits being sold for use as a drink[].
Astrocaryum macrocalyx has a very wide distribution, large population, is not currently experiencing any major
threats and no significant future threats have been identified. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2018)[].

Edible Uses

The liquid endosperm of the unripe fruit is drunk[].
The dark brown, obovate to oblong fruit is 72 - 90mm long and 29 - 34mm wide with a thin, fibrous to fleshy, orange-coloured mesocarp and a single large seed[].

The palm heart (the inner core and growing bud of the plant) is harvested from various species in this genus[]. It provides a crispy food, rich in nutrients, that can be eaten raw or cooked. Harvesting the heart will lead to the death of the plant, however, since it is unable to produce new shoots.

We have no specific information for this species, but the fruits and seeds of various species are reported to be used for oil production in the Amazon region. Existing analyses of fruit fat content show a relatively homogeneous composition among species, with around 20% of fat content in the mesocarp, mostly composed of oleic and palmitic acids, and 20-35% of fat content in the endosperm, with a predominance of lauric acid[].

Medicinal

None known

Other Uses

The hard endocarp of various Amazonian species is commonly used to make beads and ornaments for necklaces[]
