Johannesteijsmannia magnifica
In Singapore: Silver Joey (Cultivated in Singapore)
Silver joey palm is a stemless (acaulescent) understorey palm from the lowland rainforests of western Peninsular Malaysia, grown for its large silvery-backed leaves. It is endangered in the wild and needs shade, humidity and warmth to thrive in cultivation.
Johannesteijsmannia magnifica, commonly known as the silver joey palm or segalok, is a perennial species of palm from Selangor, Perak, and Negeri Sembilan, Malaysia. It grows in primary forests in tropical lowlands, and is considered endangered. It was first described in 1972 by John Dransfield, but was known to and used by indigenous Malaysians before description.
This species is endemic to Malaysia, distributed throughout the western portion of the peninsula. It grows in valley bottoms and hill slopes in evergreen tropical lowland forest, with one site occurring on limestone. It prefers unlogged primary forests with high canopy cover, and juvenile recruitment in heavily logged groves is very low. Populations of J. magnifica tend to be densely populated, but isolated from other populations, with some groups of palms being confined to particular valleys. Dispersal between these populations is low, though genetic diversity within them remains relatively high.
