Continuation of this post. I got an answer quite quickly (but after posting the previous post): The Plant List marks what species are in what genus and family, and groups families in Major Groups, e.g. gymnosperms. It also marks synonyms. With a list of conifer species and the ContentMine output, I can determine which species are not conifers, and find how they interact with each other.
