The sepals are fused to form a bell-shaped cup which is often immersed in the branch and there are four or five petals which usually fall off after the flower has opened. There are many stamens, joined for a large proportion of their length into four or five "claws".
A cup-like structure forms from fused sepals, often partially covering the branch, and is accompanied by four to five petals that usually fall away once the flower opens. The stamens are joined together for most of their length in a cluster of four to five appendages.
