Attalea dubia, also known as the Indaiá plant, babassu palm, or bacuaçu palm is a flowering plant in the palm family Arecaceae, native to the Southern and Southeast Regions of Brazil. Growing to 25m (82 ft) tall and a 35cm diameter trunk. An evergreen monocot with a moist and tropical habitat, it has a sturdy, columnar, woody trunk and fan-shaped (palmate) leaves.
Name and etymology
The Latin specific epithet dublia means "doubtful" or "variable".
Taxonomy
The first published documentation of A. dublia occurred in 1929 in a journal titled Notizblatt des Botanischen Gartens und Museums zu Berlin-Dahlem where the authors, working for the botanical garden and museum in Berlin and with Freie Universität Berlin, cataloged plant, algal, and fungal taxonomy. This taxonomy was first seen, accepted, and confirmed in 2005 by a collaborative project aiming to catalog plant families named "World Checklist of Seed Plants" and currently known as the World Checklist of Selected Plant Families.[2]
Reproduction
There are male and female flowers in the same bunch, 1–1.5 m long. The male flowers are distributed in two rows per bunch, with sepals 1–2 mm long and flat and pointed petals, 8–20 mm long by 1.5–2.5 mm wide, and 6–10 stamens. The female flowers are larger, measuring 25–40 mm in length and 15–17 mm in diameter.[3] The hardiness of A. dublia's seeds, resulting from their tough endocarp and their need to be buried for germination, make them difficult to germinate with germination taking between 4–6 months.[4]
Predation
A. dublia's fruit are predated upon by two primary organisms: A beetle species known as Pachymerus sp. and a rodent species known as Dasyprocta leporina (Red Rumped Agouti). Both prey on the fallen fruit from the palm and work in competition with one another. The beetles have larger predation against A. dublia while the fruit resides in pastures however, when in the Atlantic Forest, the rodents dominate predation. Overall, the palm seeds normally survive with up to 87% surviving at some testing sites.[5]
Uses
The fruit from the tree is popular in the creation of medicines, beauty aids, and beverages. The palm core can be harvested but its extraction often results in death and is therefore not able to be cultivated due to its importance in the local ecosystem on fauna. The fruit is composed of numerous woody oblong fruits looking similar to small coconuts.[6]
Physicochemical properties
A. dubia, often seen similar to A. speciosa, can be cultivated for its oil and thatch and lumber with nearly every part of this palm can serve some practical purpose. The oil, Indaiá Oil, is very similar compositionally to Babassu oil, an edible cooking oil that can be used in skincare and cleansers. The Indaiá oil composition is fairly similar to the Babassu oil with less unsaturated fatty acids (5.8% and 9.45%). The four main fatty acids that were present are lauric acid, myristic acid, caprylic acid, and capric acid. These same four fatty acids appear in Babassu Oil in nearly the an identical composition.[7]
Other
With Babassu Oil being used in cooking, Indaiá oil can be as well. Other uses include being used in lubricant, soaps, and cosmetics. The leaves from the palm can be used as thatching for shelter palm hearts for juices, and the high fiber concentration in the leaves and fruit being used to make handicrafts such as baskets. The trees themselves are seen as ornamental and are occasionally used as landscaping.[7]
