Haven't found a species with leaves like that, though...
It looks like it, but I can't find one with those clustered flowers.

When they grow densely you have to look closely to count the stems: dense mat; but sometimes you find a lone stem:
PS "so alone, in the stone": rhyme, meter, scansion!
Thanks for the info.

to the Unidentified flora and fauna album. Hopefully you will get help there.
