But the Lilies category wasn't called the Lilium category. I remember photos of an Ismene, a Gloriosa, a Fritillaria, and a Clivia, all of which have "lily" in their common names. I hope no one ignored those photos just because they're not in the Lilium genus. I think it would be wrong to get too strict about the categories. If all of the photos of gazanias, petunias, begonias, pelargoniums, snapdragons, fuchsias, and other perennials had been removed from the Annuals category, for instance, there'd be almost nothing left. Those tender perennials are grown as annuals in some climates, so I think their inclusion in the Annuals category is permissible.
