sex and apomixis in plant

There are quite a few examples of plants that change gender between
years. Jack-in-the-pulpits are a classic example. The same individual
may produce a male inflorescence one year and a female inflorescence
the next year. Asexually derived progeny (from division of the corm)
need not express the same gender in the same year. In such plants,
gender expression is usually size-related. (Females are larger.) There
are also fish that change gender, and again the gender change is
usually size related.

I can't think of examples of gender change in plants with agamospermy
off the top of my head, but I would not be at all surprised to learn
that there are some.
