Re: [Killietalk] Re:was Fry with velvet- medicinal dyes and plants
I have two distinct hornwort species that I believe to be a form of C.
demersum and C, submersum. My plant book (Rataj and Horeman) mentions that
C. demersum has two forked leaves and C. submersum has three forked leaves.
My two species correspond to that. The C. submersum species is much more
decorative .....at least in my tanks.
