Description

Arenga engleri, is a striking tropical species admired for its ornamental appeal. This clustering palm features multiple stems enveloped in fine black fibers, adding to its distinctive appearance.

Its lush, arching leaves have a characteristic fishtail shape. The deep green, pinnate leaflets often exhibit a gentle twist, creating a slightly spiraled effect. Each leaflet emerges from a thornless midrib, displaying a dark-green to olive hue on the upper surface and a silvery sheen underneath. Notably, the leaflets have a unique induplicate cross-section and are arranged in a single plane along the stem.

Among the foliage, the palm produces spikelike inflorescences containing both male and female flowers, allowing for self-pollination. These blossoms, available in shades of red, orange, or green, emit a pleasant fragrance. The plant eventually bears small, spherical fruits that mature to a deep red or purple color, each containing one to three seeds.
