| Hi Mike,
I've just had a look in my copy of 'The Concise British Flora in Colour' - W Keble Martin 1969 and it gives Water Forget-me-not as:
Myosotis Scorpioides L. Water Forget-me-not M. palustris (L.) Cyme not bracteate; calys hairs appressed; short, trinangualr teeth, flowers 1/4in, style equaling calyx tube. Common by ponds and streams. Flo May-Oct |
