Description section[edit]
Hello! I noticed some information on the description section which were not cited and sounded odd in general, so I have removed them and added sources. In case someone would disagree with this, I will add the original text that has been modified here for transparency and add comments [like this]:
"Equisetum palustre is a perennial cryptophyte [I've never heard of cryptophytes and although there is a link to a wiki page about it, I could not find any sources that were not citing wiki page on the matter, word for word. The only information I found that also should debunk this is that cryptophyte/cryptomonads are a group of algae, which I'm pretty sure horsetails are not part of. Hence, I added what my source says; that they are a pteridophyte], growing between 10 and 50 centimeters (4" to 20") [differed a bit from my source and there was no citation, so added my source's size], in rare cases up to one meter (3'). Its fertile shoots, which carry ears, are evergreen [firstly, horsetails do not have ears; wheat and maize do, this is where the grains or kernels develop. Second, this horsetail is not considered evergreen, because it does not have leaves that persist throughout the year, instead perennial (herbaceous) pteridophyte is a more accurate description according to my source] and shaped like the sterile shoots. The rough, furrowed stem is one to three mm in diameter with usually eight to ten ribs, in rare cases, four to 12. It contains whorled branches. The tight-fitting sheaths end in four to 12 teeth. The lower sheaths are dark brown and much shorter than the sheaths of the main shoot. The central and vallecular canals are about the same size, but the carinal channels are much smaller. The central channels measure about one sixth of the diameter of the stem.
The spores are spread by the wind (anemochory) and have four long ribbon-like structures attached to them. They sit on strobili which are rounded on the top. Marsh horsetails often form subterranean runners and tubers [not sure if they form tubers, changed to rhizomes], with which they also can proliferate vegetatively."
If the edits do not make sense, feel free to educate me! I'm by no means a professional botanist, just enjoy reading about plants and doing this type of editing. :)
