Aloe ( or ), also written "Aloë", is a genus containing over 500 species of flowering succulent plants. The most widely known species is "Aloe vera", or "true aloe", so called because it is cultivated as the standard source of so-called "aloe vera" for assorted pharmaceutical purposes. Other species, such as "Aloe ferox", also are cultivated or harvested from the wild for similar applications.
The genus Aloe contains more than 353 species of flowering succulent plants.
It's definitely correct because it contains over 500, therefore it must also contain over 353. It's difficult probably because the system might think it's not possible for both of these statements to be true at the same time.
