Jubaea

 

a genus of plants of the family Palmae. The sole species is J. spectabilis. The trunk measures 15–18 m in height and as much as 1 m in diameter. The crown consists of 60 to 100 pinnate leaves. The branching inflorescences reach 1.2–1.4 m in length, with the pistillate flowers at the base and the staminate ones on the upper section. The fruit is a drupe with a fleshy pericarp. The rounded seeds contain about 35 percent oil.

J. spectabilis grows on the Chilean coast at elevations to 1,200 m. The species has been greatly decimated. The sugary sap obtained from the trunk is used to make wine. The fruits and seeds are used in food, and the leaves are used as roof coverings. J. spectabilis is cultivated in parks along the Black Sea coast of the Caucasus (Sukhumi, Sochi).

Baill., is the only palm among continental native Chilean flora and therefore is considered a singular and important element of Chilean Mediterranean ecosystems (Gonzalez et al.

Some management systems have been regulated by law for particular species, like harvest of palm heart from Euterpe edulis in Brazil (Reis et al., 2000c) and Bolivia (Ministerio de Desarrollo Sostenible, Republica de Bolivia, 2006), sap from Jubaea chilensis in Chile (Gonzalez et al., 2009), and wood of Iriartea deltoidea in Colombia (Corpoamazonia, 2006).
Sap extraction of the austral Jubaea chilensis is regulated by seasons, and extends from mid-spring (October) to autumn (April).
In Chile, the largest stands of Jubaea chilensis are those where management for palm sap extraction has been a traditional activity (Gonzalez, 1994).

The present study shows that palm seedlings have variable length hyperphylls, which can extend to various degrees from the seed, from a few millimeters (e.g., Jubaea chilensis, Colpotrinax cookii, Nannorrhops ritchiana, Pritchiardia remota) to several centimeters (e.g., Corypha, Borassus, Phytelephas).
