simple-leaved（植物学）指具单叶的；叶片为一个完整的叶片，不分成多个小叶（区别于 compound-leaved “复叶的”）。在不同语境中也可写作 simple leaved。
/sm.pl livd/
The shrub is simple-leaved.
这灌木是单叶的。
In the field guide, the plant is described as simple-leaved, with oval blades and smooth margins, which helps distinguish it from similar compound-leaved species.
在野外图鉴中，这种植物被描述为单叶的，叶片呈卵形、叶缘平滑，这有助于把它与外形相近的复叶物种区分开来。
该词由 simple（“简单的、单一的”）+ leaved（“具……叶的”，源自 leaf “叶子”）构成的复合形容词，常见于植物形态描述，用来强调叶的结构是“单片”而非“由多个小叶组成”。
