All Leaves < 4 cm Long
The Naiads are often extremely difficult to tell apart, even for
experts. It is especially difficult to tell Najas minor and Najas gracillima
apart, as N. minor looks very much like N. gracillima when it is immature. If
the leaves are strongly recurved, you can be fairly certain you have N. minor.
If the leaves are straight and weekly toothed, it could be either species. Look
at all the hints to make sure you’ve keyed this out correctly.
If you don't think your plant is represented above try going
back a level and choosing again.
