常见错误

❌ 错误:The pistil is the male part of the flower.
✓ 正确:The pistil is the female part of the flower.

错误地将pistil误认为是雄性部分。pistil专指雌蕊,是花的雌性生殖器官;雄性部分是stamen(雄蕊)。

❌ 错误:I saw many pistils on the tree.
✓ 正确:I saw many pistils in the flowers on the tree.

pistil是花的一部分,不能直接与tree搭配。应明确指出是树上的花中的雌蕊,避免搭配不当。

近义词辨析

carpel

carpel是构成雌蕊的基本单位,一个pistil可由一个或多个carpel组成;在植物学中,carpel更强调结构单元,而pistil指整体雌性器官。

A simple pistil consists of a single carpel, whereas a compound pistil has multiple carpels fused together.

gynoecium

gynoecium指一朵花中所有雌蕊的总称,是集合术语;pistil通常指单个雌蕊,但在一些语境中可互换,gynoecium更学术化。

The gynoecium of this species includes several pistils arranged in a whorl.
