I like the additions that you have made to this article, however several pre-existing portions of the article look like they need work as well. I feel that the discussion about the invalid taxon should get its own section, and not just be covered in the opening section. The distribution section is short, and could use most specific language than "not very dry or very hot". An image of a map could be used here to display the spread of this group, if possible. The Life cycle section could use some citations, and also doesn't cover how the gametophyes form a sporophyte. The last sentence in the life cycle section is also extraneous, as it merely says what the terms are NOT rather than what they actually are. Jmcain58 (talk) 02:35, 12 April 2017 (UTC)
