An attractive, medium-sized clustering palm from an island off the coast of eastern Africa, the Dypsis pembana is one of the few Dypsis not from Madagascar. This particular palm species is endemic moist lowlands on the island of Pemba in Tanzania, and cannot be found in the wild anywhere else in the world. The âPembana Palmâ is a clustering palm, and has a pole-like deep green ringed trunk and relatively short, upright leaves with a strong arch near their tips. Mature palms develop a pronounced âfootâ (swelling at base of trunk).
