| Arenga (ah-REN-gah) |
PHILIPPINES: Palawan:: Palawan Prov. Aborlan municipality, Talakaigan
Habitat and Distribution
Southeastern Asia - Indonesia. Rainforest. Primary rainforest, only rarely in secondary growth areas, at lower elevations.Arenga brevipes is found in Borneo, and Sumatera.
Arenga brevipes is a solitary-stemmed, evergreen palm. The unbranched stem is crowned by a rosette of large leaves. The plant is harvested from the wild for local use of its edible bud. All species in this genus have either recognized or potential ornamental value. Editing by edric.
The most tender, cold sensitive Arenga. Propagation: Seed - a deep root is formed before the seedling emerges above soil level, and so the seed should be sown in individual, deep containers. Pre-soak the seed for 24 hours in warm water before sowing. It can take 3 - 6 months or more before signs of growth are seen above soil level. Keep warm, sheltered, and moist. Cold Hardiness Zone: 10a
Comments and Curiosities
Edible Uses: Leaves - cooked. The apical bud, known as a 'palm heart' is eaten as a vegetable. Eating the bud causes the death of the tree since it is unable to form side shoots.
The fruits of most species in this genus are poisonous and are sometimes used criminally. The fleshy mesocarp of the fruits usually contains many oxalate crystals, making the flesh inedible. The stem is comprised of pith and is eaten. The leaves are used for thatching and wickerwork. The taller Arenga palms store large quantities of starch in their stem that are later converted into sugar to be translocated to the inflorescences. The sugar can be drawn off in the juice by tapping the peduncle and rachis of the male inflorescence. By far the most important sugar producer in the genus is Arenga pinnata, but other species are used similarly. The starch of the stem can also be harvested.

"very attractive but very rare in cultivation, this acaulescent (stemless or trunkless), clustering Bornean palm has beautiful deep, green shiny leaves with bright white undersides. The leaves erupt out of the ground and leaflets get progressively larger towards the tip of the leaf." (Geoff Stein)
