Quoting:In a previous article I talked about the differences between monocots and dicots, something I was pretty unclear on until I wrote the article. Neither of those terms apply to Gymnosperms as Gymnosperms do not have a ‘cot'.

Gymnosperms do have cotyledons; you could arguably call them 'polycots', as many have more than the one of monocots or the two of dicots. One pine (Pinus maximartinezii) has up to 24 cotyledons, the most of any plant. But a lot of Gymnosperms do also have just two cotyledons (e.g. many cypresses, all yews, most podocarps, all ephedras, Ginkgo, etc.).
