The species is native to Borneo (Sarawak) where it lives in the underwood of the pluvial forests from the sea level up to about 700 m of altitude. The name of the genus comes from the local Malay one “salac”; the specific name is the Latin adjective “magnificus, a, um” = magnificent.
Common names: baroh, lium, remayong (Sarawak); selindung (Kalimantan).
The Salacca magnifica Mogea (1980) is an acaulous dioecious species, cespitous, with leaves, on a 0,5-1,6 m long petiole, undivided, plicate, obtriangular with toothed margins, in correspondence to the veins of the foliar segments merged together, and bifid apex, up to about 4 m long and 0,4-0,7 m broad, of intense glossy green colour above, silver grey below.
Foliar sheath, petiole and rachis are thickly armed with robust spines of various length, up to more than 6 cm, and bound towards different directions, of pale brown colour.
Inflorescences between the leaves, the male usually erect, with 2-3 orders of ramification, about 45 cm long, bearing numerous flowers arranged in couple and close, the female simple, initially erect, then curved in fruit, about 30 cm long, with several close flowers.
The fruits are pyriform of pinkish brown colour, about 5 cm long, covered by imbricate scales with pointed apex and retroflexed, containing 1-3 seeds; the cream white pulp is edible with a sweet taste. The germination is adjacent and the first leaf is bifid.
It reproduces by seed in organic loam with addition of coarse siliceous sand or agri perlite per a 30%, for a best drainage, maintained humid at the temperature of 26-28 °C, with fairly long germination times, from some months to one year; it propagates also by division, albeit with difficulty due to the presence of the spines.
Specific name absolutely right for this palm with the undivided leaves, the largest and among the most ornamental of the genus, rare in cultivation, would deserve a better diffusion, also keeping in mind the spines that limit its collocation to the large gardens and far away from the passing places.
Markedly tropical in its exigencies, requiring high and constant temperatures and ambient humidity, can be tried its cultivation in the subtropical climate zones where temperatures under the 10 °C are short lasting exceptions.
It can grow in full sun in presence of high humidity in the air and the soil, but usually prefers a partly shaded position; requires draining soils rich of organic substance, acidic or neutral, maintained constantly humid.
Useful are the fertilizations with balanced products with microelements in the form of chelates.The fruits, collected in nature, are consumed locally due to their pleasant taste, even if in a markedly inferior measure in comparison to those of the Salacca zalacca (Gaertn.) Voss , whilst the leaves are at times utilized for the covering of huts and makeshift shelters. The employment of this plant in pot for the decoration of inner spaces is not recommended because of the presence of the dangerous spines and seen the dimensions it can reach.
