Neither coconut trees nor palm trees are real trees—they're monocots, a group of plants that includes grasses, orchids, corn, and more.

椰子榈都不是真正的——它们是单子，这类包括草、兰花、玉米等。

Bamboo is also a monocarpic plant. But it can take more than 100 years for some bamboo species to flower, and even then, sometimes their roots push up new plants.

竹子也是一种单子。 但是，一些竹子品种可能需要100多年才能开花，即使这样，有时它们的根也会冒出新芽。
