Photo and magnified inset
I found 4 or 5 similar plants on the banks of a reservoir in Spain (2 are shown in the photo with magnified inset). The mm ruler shows how small they are. The flower buds are less than 1mm closed and 1.5 to 2 mm open. Each flower has 5 petals and 5 stamen. The plants grow along the ground (at least I've not seen any upright stems). The leaves are clearly succulent as can be seen from the damaged one above the leftmost red cluster that is on the ruler.

Hi Alan, thanks for sending more pictures. As you may have guessed, there is a file size limitation on this program, so it's hard to get a close up picture to show properly. I've added the pictures you've emailed me separately, which may show a bit more detail.
Unfortunately, this appears to be a plant which might be very localized to the area that you found it, so I'm not familiar with it at all.
Hopefully, another visitor to Spain might recognize this cute little guy, and set us straight.
I have seen some Crassula species that this resembles, so that might be a place to start. Have a look on this post which has a picture of a very similar flower, but the leaves, although they're similar, have little soft spines on. Sorry, I know nothing else about this plant, other than it's a Crassula: Unknown Crassula.
