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.

在某整群物中， 胚珠直立，而在物群中， 胚珠则悬空；在少数物的同个子房内， 个胚珠者的位置， 第二个胚珠后者的位置。

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， 胚珠的位置， 即使个直立而个悬置在同个子房内，也将遵循有利于它们受精和种子生产的任何轻微位置偏差的选择。
