Gymnosperms don't make nectar, but they do make nutritious pollination drops that are used for trapping airborne pollen.

裸子植物不产生花蜜，但它们确实产生有营养的授粉滴，用于捕获空气中的花粉。

This is POG, I drank this growing up, so there's definitely a lot of nostalgia with this, but it's passion fruit, orange, and guava nectar in a can.

这是 POG， 我从小就喝这个，所以定有很多怀旧之情，但它是罐装的百、子和番石榴花蜜。

Several plants habitually produce two kinds of flowers; one kind open and coloured so as to attract insects; the other closed, not coloured, destitute of nectar, and never visited by insects.

一种是开放的， 有颜色的，以吸引昆虫； 另一个是封闭的， 没有颜色，没有花蜜，也从未被昆虫光顾过。

The plants which produced flowers with the largest glands or nectaries, excreting most nectar, would oftenest be visited by insects, and would oftenest be crossed; and so in the long-run would gain the upper hand and form a local variety.

开花的植物有最大的腺体或蜜腺， 分泌最多的花蜜， 最常被昆虫光顾， 也最常杂交；因此，从长远来看， 它们将占据上风并形成本地品种。
