'''Rhapis excelsa''' (Greek rhapis, meaning "needle"; Latin excelsa, meaning "tall") also known as '''Broadleaf Lady Palm''' or '''Bamboo Palm''' is a [[species]] of fan palm (Corypheae) native to southern [[China]].

==Description==

R.''Rhapis excelsa'' grows up to 4 m. in height and 30 &nbsp;mm. in diameter in multi-stemmed clumps with glossy, palmate [[leavesevergreen]] leaves divided into broad, ribbed segments. Leaf segments are single or few in young plants and increase to 12a dozen or more in mature plants; segments are divided to the petiole. Leaf -ends are saw-toothed unlike most other palms, occurring on slender [[petiolespetiole (botany)|petiole]]s ranging from 20 to 60 &nbsp;cm. in length. New foliage emerges from a fibrous sheath which remains attached to the base. As the plants age, the sheaths fall, revealing the [[bamboo]]-like trunks. This usually [[dioecious]] palm species produces a small [[inflorescence]] at the top of the plant with spirally-arranged, fleshy yellow flowers containing three petals fused at the base. Ripe fruit are fleshy and white, though they''R. excelsa'' more readily propagatepropagates via underground [[rhizome]] offshoots.

In the UK this plant has gained the [[Royal Horticultural Society]]'s [[Award of Garden Merit]].<ref name = RHSPF>{{cite web
