What is "rhapis"

Rhapis is a genus of about 10 species of small palms native to southeastern Asia from southern Japan and southern China south to Sumatra. The species are commonly known as Lady Palms. They are fan palms (Corypheae tribe), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. The plants have thin stems growing to 3–4 m tall, branching at the base, forming clumps and are dioecious, with male and female flowers produced on separate plants. Rhapis is closely related to the Maxburretia and Guihaia genera and with them form a taxon within Thrinacinae represented by carpel specialization.
