I forgot how complicated plant sex was. https://en.wikipedia.org/wiki/Plant_reproductive_morphology#Use_of_sexual_terminology

"Plants have a complex lifecycle involving alternation of generations. One generation, the sporophyte, gives rise to the next generation via spores. Spores may come in different sizes (microspores and megaspores), but strictly speaking, spores and sporophytes are neither male nor female. The alternate generation, the gametophyte, produces eggs and sperm. A gametophyte can be either female (producing eggs), male (producing sperm) or hermaphrodite (monoicous, producing both eggs and sperm).

In groups like liverworts, mosses and hornworts, the dominant generation is the sexual gametophyte. In ferns and seed plants (including cycads, conifers, flowering plants, etc.) the sporophyte is by far the most dominant generation. The obvious visible plant, whether a small herb or a large tree, is the sporophyte, and the gametophyte is very small."

Edit: this wasn't even in Biology class. Weird hybrid sex! https://en.wikipedia.org/wiki/Parthenogenesis#Hybridogenesis And it's how the edible frog reproduces.
