A solitary or clustering palm with stems to 5 m tall, ca. 3 cm diameter. The leaves are rarely more than 8 in the crown, are strongly arcuate and have few distant, sigmoid, grouped dark green leaflets. The most remarkable feature is the leaf sheath, which is covered, towards the sheath mouth, with irregular warty excrescences, a feature observed on all individuals, and not known on any other palm species. The inflorescences are interfoliar, and have few robust long rachillae. Staminate flowers are globular, creamy yellow, relatively large and have six stamens with more or less sagittate anthers.
This and D. lilacina grow together, intermingled in the undergrowth of ridge-top forest together with D. saintelucei and D. culminis. A newly described species from Mt. Ivohibe in south Madagascar.
Native to, Madagascar
