Water Fern Azolla filiculoides 36 |

Alders Brook, 16 February 2008

When found in 2008 there was a lot of this fern in the Alders Brook near to the barrage beneath the railway lines. This can be seen in the other photograph. However, as is often the case with this species, in subsequent years it did not appear - or, at least, was not noticed. |
