Snowdrops and Snowflakes

We have several types of Snowdrops on the chalk streams. Most are the common ones seen in the first image, with the Avon providing the background. Piscatorial Society Head Keeper Stuart Mcteare told me there were also rare wild growing Snowflakes on the Avon. Snowflakes are a separate plant but similar to Snowdrops. Having gone in search of them at the location I thought Stuart had indicated, all I found were a few unusual wider opening Snowdrops (called I think Galanthua Navalis Flore Pleno). Sending Stuart a photograph of them later, I said he must be mistaken about the Snowflakes. I should have known better than to doubt Stuart. After getting redirected for my next trip I found a huge bunch of Snowflakes in an infrequently visited site next to the Avon. Quite show as you can see from the bottom two images.
