Article Evaluation: Rubiaceae

The information is all relevant because it is primarily scientific facts about the family Rubiaceae. Also, because the article is scientific there is no noticeable bias on the page. The first link in the article is likely where the cited information came from but, it does not link directly to information about the family Rubiaceae. This citation could be stronger if it connected the reader directly to the discussed information about the family Rubiaceae. The source (Missouri Botanical Garden) does seem to be reliable however. Considering that this information is scientific and established, it should not need to be updated.
