In certain whole groups of plants the ovules stand erect, and in others they are suspended; and within the same ovarium of some few plants, one ovule holds the former and a second ovule the latter position.

在某些整群物中， 胚珠，在另一些物群中， 胚珠则悬空；在少数物同一个子房内， 一个胚珠占据前者， 第二个胚珠占据后者。

If so, the position of the ovules, even when one is erect and the other suspended within the same ovarium, would follow the selection of any slight deviations in position which favoured their fertilisation, and the production of seed.

如果是这样， 胚珠， 即使一个另一个悬在同一个子房内，也将遵循有利于它们受精和种子生产任何轻微偏差选择。
