Much of the flora was miniscule. However, it was a great opportunity to test my new toy, a x10 macro lens you can just clip onto a smart phone. Did a good job and a bargain at £10 from Amazon. I will have to see if there is a lower magnification version, as with x10 you are nearly on top of the subject before it comes into focus. Fine for plants, but critters are likely to be less obliging.
Anyway the results below. Best find was Sand Spurrey (Spergularia rubra), hiding amongst the Buttonweed (Cotula coronopifolia) which was also very small but towered over these plants. Also present was Pink Water-speedwell (Veronica catenata) and Swinecress (Lepidium coronopus). In sequence below.
