I must admit, when I speak of all parts varying, that ovules, as far as is known do not vary probably wd result, from long series of changes in adult plant — so we do not know whether embryo of animals vary, except in result. There being no adaptation, in ovule there can be no selection of it, at ovule, so only indirect — will depend on law of development & growth of which we know nothing.
