In a small river.
No interactions present.
... the left hand photograph is Callitriche whilst most of the right hand photograph is Lagarosiphon major.
use of palustris in the title is misleading as it is very unlikely to be this species - can you change it just to Callitriche please?
I changed it. I had left a question mark with the species name so that someone could tell me whether it was or wasn't the right one.
Is it impossible to tell from this picture which species it is? Which feature would I have to look out for to be able to tell the species?
fruits and leaves - complicated genus which needs examining carefully - need good guide like BSBI Handbook http://www.summerfieldbooks.com/showdetails.asp?id=1894
Thank you for your expertise. I will keep that in mind.
