Talk:Tree

A lot of information without sources

The second and third paragraphs have a lot of good information but no sources to go with them. Alexajim (talk) 00:36, 24 February 2017 (UTC)

Thanks for pointing that out. A lead section is supposed to summarize the content that's presented in more detail within the body of an article. If the detailed content is adequately sourced, references aren't generally required for the summary content. (There are exceptions, but it's true for the most part. See WP:LEADCITE.) If you find something in the second or third paragraphs that isn't sourced later in the article, please note it here. Rivertorch^FIRE_WATER 04:47, 24 February 2017 (UTC)

Trees as vascular plans.

I have deleted the following text:

Trees exist in two different groups of vascular or higher plants, the gymnosperms and the angiosperms. The gymnosperm trees include conifers, cycads, ginkgophytes and gnetales; they produce seeds which are not enclosed in fruits, but in open structures such as pine cones, and many have tough waxy leaves, such as pine needles.Most angiosperm trees are eudicots, the "true dicotyledons", so named because the seeds contain two cotyledons or seed leaves. There are also some trees among the old lineages of flowering plants called basal angiosperms or paleodicots; these include Amborella, Magnolia, nutmeg and avocado, while trees such as bamboo, palms and bananas are monocots.

We just finished saying that tree ferns and lycophytes are trees, and while they are vadcular plants, they are neither gymnosperms nor angiosperms. As such, saying that trees only exist inthose two groups is just plain wrong. Mark Marathon (talk) 01:48, 20 September 2017 (UTC)

Um, something useful is being stated in the paragraph: there's no need to read anything exclusive into it. We could restate it as "there are by the way trees in both the gymnosperms and the angiosperms...", which is true and helpful - indeed, the great majority of trees are in these groups. I'll have another try. Chiswick Chap (talk) 20:49, 14 November 2017 (UTC)
