Ravenea rivularis
 Ravenea rivularis is an endangered species of flowering plant in the Arecaceae family.The extremely elegant fast-growing majesty palm has upward-arching leaves that are divided into long thin fingers. It makes a fine conservatory feature plant but make sure the roof is high enough because in the right conditions it can get quite tall. Relatively easy to grow it tolerates low light and cool conditions but needs decent summer humidity- a dry atmosphere can be fatal.
