花被片（Tepal）是花被的一部分，包括花瓣和萼片。花被片一词常用于当花被的形状和颜色相似时。

未分化的花被片被认为是被子植物的一种原始状态。花瓣和萼片的分化可能是受到了动物传粉的影响。典型的现代花朵，外部围绕着萼片以保护花芽，而内部的花瓣则是为了吸引授粉者。

一些植物的花朵无花瓣，而其萼片变化得类似于花瓣。这些组织被描述为“花瓣状”，如铁筷子属植物的萼片。

单子叶植物的花被片通常未分化。如郁金香，形成了两轮花瓣状的结构，其基部混合成一个大型，艳丽的六瓣结构。虽然这两轮结构差不多，但实际上第一轮是独立于第二轮的组织。所以，这样整部分被称之为花被。

A tepal is one of the outer parts of a flower (collectively the perianth) when these parts cannot easily be divided into two kinds, sepals and petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in Magnolia, or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in Lilium). The term was first proposed by Augustin Pyramus de Candolle in 1827. (De Candolle used the term perigonium or perigone for the tepals collectively; today this term is used as a synonym for "perianth".)
